Runs on your device
Your file is opened and processed by JavaScript inside this page. It is never uploaded and we never receive it. The page does download the processing library it needs from a public CDN the first time you use it - that request carries no part of your file.
Free tier: 5 runs per day for this tool, counted in your browser. The counter resets at midnight UTC and is not shared between browsers or devices.

What this tool is for
- Cutting a clip out of a longer recording
- Trimming dead air off the start of a screen capture
| What it does | Cuts a video down to a start and end point you choose, using ffmpeg.wasm running in your browser. |
|---|---|
| Accepted input | One video file (video/*), plus the start and end points. |
| What you get back | The trimmed video. |
| Limits | Capped at 5 runs per day for this tool. ffmpeg.wasm downloads on first use and everything is held in memory. |
| Browser requirements | A current desktop browser with plenty of free memory. Large files will fail on a phone. |
A worked example
- Input
- A 3-minute screen recording, trimmed from 00:12 to 00:47.
- What comes back
- A 35-second video containing just that section.
- Worth knowing
- ffmpeg.wasm runs the whole encode in your browser's memory, so this is much slower than a desktop editor and a long or high-resolution source can exhaust the tab. Work from clips rather than hour-long recordings.
If it does not work
The tab crashed or ran out of memory
The file is too large to hold in browser memory. Use a shorter or lower-resolution source.
It is extremely slow
Expected - the encoder is compiled to WebAssembly and runs on your CPU.
The first run takes a long time to start
ffmpeg.wasm is downloading from the CDN.
Nothing happens on Save
You may have used your 5 runs for this tool today.

When to use Video Trimmer
Cutting a clip for social media
Keep the best few seconds of a longer recording.
Removing dead time
Cut the start and end of a screen recording or a phone video.
Preparing a clip to convert or turn into a GIF
Trim first so later steps work on less video.
Sharing just the relevant part of a call recording
Cut a recorded meeting down to the five minutes a colleague needs, rather than sending the whole file.
How it works
Video Trimmer runs ffmpeg.wasm in your browser. You set the start and end points while the video plays:
- Scrub the player
- Find the moment you want to start or end.
- Jump to start / Jump to end
- Place the handles at the current position.
- Save Trimmed Video
- Encode and download the section between the handles.
What it cannot do
- The whole video is held in your browser's memory, so long or high-resolution files can crash the tab. Work from clips, not hour-long recordings.
- It is much slower than a desktop editor because the encoder runs on your CPU in the browser. The first run downloads ffmpeg.wasm, a video engine compiled for the browser, so it takes longer to start.
- It cuts one section; it does not join clips, add titles or edit audio.
- The free allowance is 5 runs per day for this tool, counted in your browser and reset at midnight UTC.
How it compares with the alternatives
The Photos app on Windows, QuickTime on Mac and the editors built into phones trim videos instantly and handle large files. If you have one of those, it is the faster option.
This tool trims a short clip in any desktop browser without installing anything or uploading the video.
How in-browser processing works, and exactly which tools are the exception, is explained on the why client-side page.
Getting a better result
Use a desktop browser with free memory
Close other tabs before trimming larger files.
Trim short clips
The shorter the source, the faster and safer the trim.
Check the cut points
Play from the start handle before saving.
Trim before converting
Smaller inputs make every later step faster.
Keep the original
Store the untrimmed file until you have checked the trimmed clip.
More questions about Video Trimmer
Is my video uploaded?
No. It is trimmed in your browser.
Why did the tab crash?
The file was too large to hold in memory. Use a shorter or lower-resolution source.
Why is the first trim slow to start?
The video engine downloads on first use.
Can I join two clips?
No. It trims one section at a time.
Does trimming reduce quality?
The trimmed section is re-encoded in the browser, so expect a small quality change; check the result before deleting the original.

Is my video uploaded?
No. ffmpeg.wasm runs inside your browser; the file never leaves your device.
Why is it so slow compared to a desktop app?
Because the encoder is running as WebAssembly in a browser tab rather than as native code with hardware acceleration.
What size of file can it handle?
There is no fixed cap, but everything is held in memory. Short clips on a desktop browser are the realistic use.
Is there a limit?
Yes - 5 runs per day for this tool.
