Free Online FPS Test – Check Your Frame Rate, Stability and Display Performance

Want to know how smoothly your browser and screen are rendering motion? Use our FPS Tester to run a free FPS test online and measure your browser’s frame-rate performance in real time.

You can use the tool as an FPS checker, frame rate tester, frames per second test, browser FPS test, screen FPS test, monitor FPS test, live FPS counter, and online frame rate test.

Run the FPS test here:

Frame Rate Tester
Open the FPS Tester

The benchmark measures current FPS, average FPS, minimum FPS, peak FPS, frame consistency, estimated screen refresh rate and total rendered frames.

Unlike a simple FPS counter that shows only one changing number, this benchmark collects performance information across the test so you can better understand rendering stability.

What Is FPS?

FPS stands for Frames Per Second.

It describes how many individual frames are produced or rendered during one second.

For example:

• 30 FPS = approximately 30 frames each second
• 60 FPS = approximately 60 frames each second
• 120 FPS = approximately 120 frames each second
• 144 FPS = approximately 144 frames each second
• 240 FPS = approximately 240 frames each second

Frame rate is commonly used when discussing games, video, animation and computer graphics.

For additional background on the concept, see the Wikipedia explanation of frame rate. Frame rate explained on Wikipedia

A higher frame rate can make motion appear smoother, but maximum FPS isn’t the only factor that matters.

Frame consistency matters too.

A stable 60 FPS experience can look smoother than performance that repeatedly jumps between 120 FPS and 30 FPS.

That is why this frame rate checker reports multiple performance measurements instead of relying only on peak FPS.

How to Check FPS Online

If you’re wondering how to check FPS or how to test FPS, you can run the benchmark directly from your web browser.

Use the FPS tester here:

Run the online FPS test

Then:

1. Select your preferred test duration.
2. Choose a rendering workload.
3. Start the FPS benchmark.
4. Keep the browser tab visible.
5. Watch the real-time FPS counter.
6. Review your average, minimum and peak FPS.
7. Compare the results with your expected display refresh rate.

Running several tests under the same conditions gives you a better comparison than relying on one result.

How Does the Browser FPS Test Work?

This browser FPS test uses an animated HTML canvas and the browser’s requestAnimationFrame() system to render and measure frames.

requestAnimationFrame() tells the browser to run an animation callback before the next repaint.

According to MDN, its callback frequency will generally correspond with the display refresh rate, although browser and device conditions can influence actual results.

You can read the technical explanation in the official MDN requestAnimationFrame documentation. MDN requestAnimationFrame documentation

This makes the technique useful for:

• Browser FPS testing
• Animation FPS testing
• Frame-rate checking
• Motion testing
• Smoothness testing
• Browser rendering comparisons
• High-refresh display testing

The benchmark shouldn’t be confused with a game benchmark that directly measures FPS inside a separate game.

What Does Current FPS Mean?

Current FPS is the latest calculated frame-rate measurement.

It works much like a real-time FPS counter or FPS meter.

You may notice that the value changes while the benchmark runs.

Small fluctuations are normal because the browser, operating system and other applications may perform work at the same time.

Repeated major drops are more significant than tiny variations.

What Does Average FPS Mean?

Average FPS summarizes performance across the benchmark.

For example, your current FPS may move between 57 and 60 while the average remains close to 59 FPS.

Average FPS is generally more useful for comparison than one momentary peak.

If you’re comparing:

• Two browsers
• Two computers
• Two power settings
• Different browser configurations
• Light and heavy workloads

compare the average FPS under similar conditions.

What Does Minimum FPS Mean?

Minimum FPS is the lowest observed frame-rate sample during the benchmark.

A low minimum compared with the average can indicate a temporary performance interruption.

Possible causes include:

• CPU activity
• GPU workload
• Background applications
• Browser extensions
• Other browser tabs
• Power-saving settings
• Operating-system processes
• Thermal behavior

One unusually low frame isn’t enough to diagnose a hardware issue.

Run the benchmark several times before drawing conclusions.

What Does Peak FPS Mean?

Peak FPS shows the highest frame-rate measurement reached during the test.

Maximum FPS is useful, but it shouldn’t be viewed by itself.

Consider these hypothetical results:

Result A

Average: 143 FPS
Peak: 145 FPS

Result B

Average: 88 FPS
Peak: 165 FPS

Although Result B has a higher peak number, Result A demonstrates much more consistent performance.

For an FPS benchmark test, average FPS and stability are usually more informative than a single maximum reading.

Why Frame Stability Matters

Smooth animation requires frames to arrive consistently.

Browser performance documentation from MDN explains that maintaining a high and steady frame rate is important for smooth animation. A 60 FPS animation gives the browser roughly 16.7 milliseconds between frames.

Chrome’s performance documentation similarly discusses dropped frames and animation performance. Chrome rendering performance guidance

If the browser takes too long to produce a frame, users may notice stuttering or visual “jank.”

That is why a useful smoothness test looks at consistency instead of simply chasing the highest FPS number.

FPS Test Load Levels

Different devices handle different workloads.

Your FPS test lets users apply different animation loads so they can compare performance.

Light FPS Test

Use a lighter workload for:

• Basic FPS checking
• Older computers
• Laptop FPS testing
• Low-power devices
• Browser comparisons

A Light test is useful if you simply want to check whether browser animation appears smooth.

Balanced FPS Test

Balanced mode increases the rendering workload.

It’s a good choice for a normal PC FPS test, computer performance test, or browser comparison.

Stress FPS Test

The heavier workload is useful when investigating:

• FPS drops
• Browser rendering limits
• Frame-rate consistency
• Performance differences
• Background workload effects

Lower FPS under a heavier workload isn’t necessarily evidence that something is wrong.

The benchmark is intentionally doing more rendering work.

FPS and Browser Rendering Performance

Smooth browser animation depends on the browser being able to complete rendering work in time for the next frame.

Google’s web performance documentation explains that when the browser fails to complete the necessary work within its frame budget, frame rate can fall and motion can appear less smooth.

Chrome DevTools even includes Frame Rendering Stats, which can display real-time FPS estimates and dropped frames while webpages are running.

If you want a more advanced developer-oriented comparison, see Google’s Chrome DevTools documentation. Chrome Frame Rendering Stats documentation

Our online FPS checker provides a simpler approach for users who don’t want to open developer tools.

What Is Refresh Rate?

Refresh rate tells you how frequently your display updates its image.

It’s measured in Hertz (Hz).

For example:

• 60 Hz = approximately 60 screen refreshes per second
• 120 Hz = approximately 120 refreshes per second
• 144 Hz = approximately 144 refreshes per second
• 165 Hz = approximately 165 refreshes per second
• 240 Hz = approximately 240 refreshes per second

For more background, see Wikipedia’s refresh-rate reference. Refresh rate on Wikipedia

FPS vs Hz: What’s the Difference?

FPS and Hz aren’t the same thing.

FPS describes the rate at which frames are produced.

Hz describes how often the display refreshes.

For example, a game may render at 120 FPS while running on a 60 Hz monitor.

Likewise, a 144 Hz monitor doesn’t guarantee that every application will produce 144 FPS.

Frame rate depends on software performance, while refresh rate is a display characteristic.

Wikipedia also distinguishes refresh rate from the frame rate generated by the device driving the display.

Refresh Rate Test

This FPS tester estimates a display mode based on observed browser frame-rate performance.

It can therefore be useful as an approximate:

• Refresh rate test
• Monitor refresh rate test
• Screen refresh rate checker
• Monitor Hz checker
• Display refresh rate checker
• Hz test

However, an online browser benchmark shouldn’t be treated as a direct hardware specification reader.

For exact Windows display settings, verify your configured refresh rate through Windows.

Microsoft explains that refresh rate is the number of times per second that a screen refreshes and provides instructions for viewing or changing it through Advanced display settings. Microsoft guide to changing monitor refresh rate

60 FPS Test and 60Hz Test

60 FPS remains one of the most common performance targets.

At 60 FPS, each frame has roughly 16.7 milliseconds before the next frame.

A standard 60 Hz display refreshes approximately 60 times per second.

If browser animation remains consistently around 60 FPS on a properly configured 60 Hz display, the browser is generally keeping up with the display’s refresh cycle.

Run your 60 FPS test here:

Check 60 FPS online

120 FPS Test and 120Hz Test

120 Hz screens are increasingly common in gaming monitors, phones, tablets and premium laptops.

A 120 FPS test can help show whether browser-rendered animation is approaching the refresh range expected from a 120 Hz environment.

Run the test under consistent conditions for a meaningful comparison.

144 FPS Test and 144Hz Test

A 144 FPS test is particularly popular among gaming-monitor users.

If you own a 144 Hz display but your FPS test repeatedly stays near 60 FPS, first check your operating-system display settings.

Your monitor may support 144 Hz while still being configured to run at 60 Hz.

Microsoft’s display settings guide can help Windows users verify this configuration.

165 FPS Test and 165Hz Test

165 Hz gaming monitors provide a higher refresh frequency than 144 Hz displays.

A 165 FPS test can help you compare browser animation performance with the expected high-refresh range.

Results still depend on browser behavior, workload and system configuration.

240 FPS Test and 240Hz Test

A 240 FPS test is relevant to users with high-end high-refresh monitors.

Competitive gaming displays commonly offer refresh rates well above 60 Hz.

If your browser and system can keep up with the display’s animation cycle, observed FPS may move into a much higher range.

360 FPS Test

Some modern gaming monitors support 360 Hz and higher refresh rates.

However, browser-based results at extremely high refresh rates should be interpreted cautiously.

This tool isn’t intended to certify the physical capabilities of a 360 Hz monitor.

Use the manufacturer’s specifications and operating-system display information when exact hardware verification is required.

Monitor FPS Test

Users frequently search for a monitor FPS test, but technically the monitor doesn’t generate application FPS.

Software produces frames.

The display refreshes them.

A monitor FPS test therefore helps you compare browser-rendered frame frequency with your current display environment.

Screen FPS Test

A screen FPS test can help answer questions such as:

• Does animation appear smooth?
• Does the browser appear to be running near 60 FPS?
• Is my high-refresh screen operating above 60 FPS?
• Do frame rates drop under heavier browser workloads?

Keep the FPS test tab visible while running the benchmark because browsers may reduce animation activity in background tabs.

MDN notes that requestAnimationFrame() is commonly paused in background tabs or hidden frames to improve performance and battery life.

Display FPS Test

Use the display FPS test to observe browser-rendered motion under your current setup.

Results can vary based on:

• Monitor settings
• Browser
• Operating system
• Current system workload
• Display refresh rate
• Battery mode
• CPU/GPU availability

For fair comparisons, keep these variables as similar as possible.

Browser FPS Test

A browser FPS test is different from an in-game FPS benchmark.

It measures how smoothly a browser renders the test workload.

This can be useful for comparing:

• Chrome vs Firefox
• Edge vs Chrome
• Different browser settings
• Hardware acceleration settings
• Laptop power modes
• Performance before and after closing background applications

Browser Performance Test

Browser performance includes much more than FPS.

Page rendering, JavaScript, layout, painting, memory and other processes can contribute to how responsive a webpage feels.

Chrome’s documentation explains that browser rendering involves multiple stages, including style calculation, layout and painting. How browser rendering works – Chrome Developers

This FPS tester focuses specifically on animation-frame rendering performance.

PC FPS Test

There’s no single universal “computer FPS.”

FPS depends on the application.

Your browser can produce one frame rate while a game produces a completely different frame rate.

Use this online PC FPS test to measure the browser workload on this page.

For game-specific performance, use an in-game benchmark.

Laptop FPS Test

Laptop performance may change depending on the power mode.

Try running the same FPS benchmark:

• On battery
• Connected to power
• In energy-saving mode
• In balanced mode
• In performance mode

Microsoft notes that higher display refresh rates can use more power, while reducing refresh rate may help conserve battery.

GPU FPS Test

Your GPU may influence browser rendering, but this tool isn’t a complete GPU FPS test.

It doesn’t directly measure:

• GPU utilization
• GPU clock frequency
• VRAM bandwidth
• Shader throughput
• Ray-tracing performance
• Graphics-card temperature

Use a dedicated graphics benchmark when you need detailed GPU measurements.

Graphics Performance Test

This tool does render animated graphics, so it can be useful as a lightweight graphics performance test for the browser.

However, it shouldn’t replace professional 3D graphics benchmarks.

Its main purpose is to measure the frame rate produced by this specific browser workload.

Gaming FPS Test

A true gaming FPS test measures FPS inside an actual game.

This browser tester can’t directly read FPS from a separate game such as Fortnite, Valorant, Minecraft, Counter-Strike, Apex Legends or Call of Duty.

Use an in-game FPS counter or compatible monitoring software when you want actual game FPS.

Our tool instead answers:

“How smoothly is my browser rendering this test?”

Game FPS Checker vs Browser FPS Checker

A game FPS checker connects to or runs inside the game environment.

A browser FPS checker measures browser-rendering performance.

They serve different purposes.

This distinction is important because a high browser FPS result doesn’t guarantee identical performance in demanding 3D games.

What Is Good FPS for Gaming?

The ideal FPS depends on the game, display and player’s priorities.

As a broad guide:

30 FPS

Can be playable for some slower-paced games but will generally appear less fluid than higher frame rates.

60 FPS

A common target for smooth gaming and browser animation.

120 FPS

Very smooth when paired with an appropriate high-refresh display.

144 FPS

Popular among PC gamers with 144 Hz monitors.

165 FPS

Common target for users with 165 Hz gaming displays.

240 FPS

Often associated with high-refresh competitive gaming setups.

Higher isn’t automatically better if performance is highly unstable.

Why Is My FPS Low?

A low FPS test result doesn’t automatically mean your computer is faulty.

Possible causes include:

Background Apps

Programs running behind your browser can consume resources.

Browser Tabs

Multiple active websites may use CPU, memory and graphics resources.

Browser Extensions

Extensions can add additional browser processing.

Heavy Test Load

The Stress test intentionally requires more rendering work.

Power-Saving Mode

Laptop and mobile devices may reduce performance to extend battery life.

Heat

Computers may reduce performance under high thermal conditions.

Browser Configuration

Browser settings and rendering configuration can influence performance.

How to Improve Browser FPS

Try the following before running another FPS benchmark test:

1. Close unnecessary browser tabs.
2. Close background applications.
3. Keep the FPS tester tab active.
4. Check your browser’s graphics or hardware-acceleration settings.
5. Plug in your laptop if performance is limited on battery.
6. Verify your display refresh-rate setting.
7. Keep your device adequately ventilated.
8. Run several tests instead of relying on one result.

Then repeat the benchmark:

Run the FPS benchmark again

FPS Speed Test

An FPS speed test is different from an internet speed test.

Internet tests measure bandwidth, ping or latency.

FPS testing measures how frequently frames are rendered.

You can have:

• Fast internet with low FPS
• Slow internet with high FPS

They measure different parts of the computing experience.

FPS Calculator

FPS can be calculated using a simple formula:

FPS = Total Frames ÷ Time in Seconds

For example:

120 frames ÷ 2 seconds = 60 FPS.

Our tester performs frame-rate calculations automatically, so you don’t need to use a separate FPS calculator during the benchmark.

Motion Test and Smoothness Test

A motion test or smoothness test focuses on how consistently visual content moves.

Higher FPS generally allows more frequent visual updates, but stable timing remains important.

Watch both the moving animation and your FPS measurements.

Frequent large frame-rate drops may correspond with less consistent motion.

Animation FPS Test

Because this benchmark continuously renders animated graphical objects, it can function as an animation FPS test.

That makes it especially relevant for:

• Browser animation
• Web rendering
• Interactive websites
• Motion-heavy interfaces
• High-refresh browsing

Video FPS Test

A video FPS test normally examines the frame rate encoded inside a video file.

For example, a video might be recorded at:

• 24 FPS
• 25 FPS
• 30 FPS
• 60 FPS
• 120 FPS

This browser benchmark doesn’t inspect video files.

It measures real-time browser animation instead.

For general background about video frame rates, see Wikipedia’s video reference. Video frame rate reference on Wikipedia

How to Test FPS Properly

For more reliable comparisons:

1. Keep your browser tab visible.
2. Use the same browser.
3. Select the same test duration.
4. Select the same rendering load.
5. Close unnecessary applications.
6. Avoid changing tabs.
7. Repeat the benchmark several times.
8. Compare average FPS.
9. Look for repeated frame drops rather than one unusual reading.

Controlled conditions make benchmark comparisons more meaningful.
