Trim Video Online Free
Video Trimmer lets you trim video online free — cut a clip out of an MP4, MOV, or WebM right in your browser. There is no watermark, no sign up, and no upload: your video is trimmed on your own device using WebAssembly, so the file never leaves your phone or computer and nothing is stamped on the result. Set the start and end on the timeline, choose a cut method, and the clip downloads straight to you.
Got a clip to cut? It takes three steps.
Trim a video free →How to Trim a Video Online for Free
Here is how to trim a video online for free in three steps — the same on desktop, iPhone, and Android:
- Open capsuletools.app/video-trimmer/ and tap Select a video to choose an MP4, MOV, or WebM file.
- Drag the two handles on the timeline to set the start and end of your clip — the preview jumps to the exact frame as you drag, so you cut precisely where you mean to.
- Pick Clean cut or Fast cut, tap Cut video, then tap Save video to download the trimmed clip.
That is all there is to it — no software to install, no watermark, and nothing uploaded to a server.
Video Trimmer Online — Free, No Watermark, No Sign Up
Most online trimmers send your video to their servers, make you wait in a queue, and stamp a watermark on the result unless you pay. This video trimmer is free and fully online, but it works differently: it runs FFmpeg compiled to WebAssembly directly in your browser, so the cut happens on your device. Nothing is uploaded, there is no sign up and no account, and there is never a watermark. You can even install it to your home screen and trim videos offline like a native app.
Supported Formats: MP4, MOV, and WebM
The tool reads the most common video formats, so you can trim MP4 online free or cut any of these without converting first:
- Trim MP4 — the most common video format, used by most cameras, screen recorders, and downloads.
- Trim MOV — the format the iPhone and many cameras record in.
- Trim WebM — the open web video format.
- MP4
- MOV
- WebM
- M4V
Fast Cut vs. Clean Cut — Which Should You Use?
The tool offers two ways to cut, so you can choose between exact precision and instant speed:
- Clean cut (default) — re-encodes the selected segment so the clip starts and ends exactly on the frames you chose. Use it when the precise cut point matters. It takes a little longer and outputs a standard MP4.
- Fast cut — copies the original video stream without re-encoding, so it finishes almost instantly and is completely lossless. It snaps the start to the nearest keyframe, so the cut may begin a moment earlier than the handle. Use it for big files or when you want to keep 100% of the original quality.
How to Cut MP4 Video Without Losing Quality
To cut MP4 video without losing quality, choose Fast cut: it copies the original stream byte-for-byte, so the trimmed file is identical in quality to the source — nothing is re-compressed. If you need the cut to land on an exact frame instead, Clean cut re-encodes at a high bitrate so the loss is visually negligible. Either way there is no watermark and no upload, so you keep a clean, full-quality clip.
Frequently Asked Questions
Is this video trimmer free with no watermark?
Yes. This is a completely free video trimmer with no watermark, no sign up, and no account. There is no upload either — your video is cut entirely in your browser using WebAssembly, so the file never leaves your device and nothing is ever stamped on the result. Trim as many videos as you like.
Can I trim a large video file online for free?
Yes. Because the tool runs in your browser instead of uploading to a server, there is no upload queue and no size limit imposed by a website — you can trim a large video online free, up to around 2 GB depending on your device's memory. For very large files, use Fast cut: it copies the video stream without re-encoding, so it finishes almost instantly and uses far less memory.
Does trimming a video reduce quality?
It does not have to. Choose Fast cut and the tool copies the original video stream byte-for-byte, so the trimmed clip keeps 100% of the source quality — nothing is re-encoded. Clean cut re-encodes the clip for a frame-accurate edit, which is how you cut MP4 video without losing visible quality at a high bitrate. If keeping the exact original quality matters most, Fast cut is lossless.
How do I trim a video online for free?
To trim a video online for free, open the tool, choose an MP4, MOV, or WebM file, and drag the two handles on the timeline to set the start and end of the part you want to keep. The preview jumps to the exact frame as you drag. Pick Clean cut or Fast cut, tap Cut video, then Save video. The whole process runs in your browser with no upload and no sign up.
Can I trim MP4, MOV, and WebM files?
Yes. The tool trims MP4 (the most common format), MOV (what the iPhone and many cameras record), and WebM. Just select the file and the same start/end timeline and cut controls apply to every format. Fast cut keeps the original container, while Clean cut outputs a standard, widely-compatible MP4. On iPhone, open the page in Safari to trim a video free from your camera roll.
