Trim video
Drag the handles or type the times, and keep or cut out as many parts as you like. The video is copied without re-encoding, so it is quick and loses nothing; tick Precise for a cut exact to the frame.

How it works
- Drop a video anywhere on this page.
- Drag the start and end handles under the player, or type the times; add more parts if you need them.
- Press Trim video and download the result, in the same format as your video.
Cutting without waiting
By default the video is not re-encoded: the packets you keep are copied into a new file, so a two-gigabyte recording is cut in seconds, on a laptop or a phone, and the picture is exactly as it was. The only catch is that a copied cut can start only on a keyframe, so the start may move back by a fraction of a second; the result line says by how much.
Tick Precise cut when the frame has to be exact, for a clean cut at a scene change or a clip that must start on a beat; that re-encodes at about the source's bitrate and takes longer, roughly as long as a conversion of the kept length.
Removing a part from the middle, keeping several
Add up to 20 parts. With Keep the parts, the parts are joined in time order into one file: the three good takes from a long recording, for instance. With Remove the parts, what you mark is cut out and the rest joined: a pause, a mistake, an ad break. Type times as m:ss.s or seconds, or move the handles under the player; play the outlined part to check it before trimming.
Phone videos, formats and sound
MP4, MOV, M4V, WebM and MKV are accepted, up to 2 GB each and 5 videos per run with the same cuts. A MOV from an iPhone comes out as MP4, which holds the same streams and plays everywhere; otherwise the format stays, or you choose MP4, WebM or MKV. The sound is copied with its timing, so it stays in sync. The browser reads the file in pieces on your device, and the counter under the result shows nothing was sent.
Why people use it
Free, no account
Every tool is free, with no sign-up, no e-mail address and no limit on how often you use it.
Your files stay on your device
The browser opens the file and processes it in memory, on your device. Nothing is uploaded, so nothing can be kept, leaked or looked at.
No watermark
The result is yours as it is: no watermark, no branding, no trial version.
Any device
A phone, a tablet or a computer with a current browser is enough: no app to install, no software to update.
Works offline after the first visit
The browser keeps the pages and their engines, so a tool you have opened once keeps working without a connection.
Open-source engines
The code that does the work is open-source software, named on the Licences page, running as WebAssembly in your browser.
Why it is private
Everything you type or drop here is handled by your browser, on your device. Nothing is uploaded. To verify, open your browser's developer tools, go to the Network tab, and use the tool: you will see no request carrying your data.
While a file is being processed, the counter under the result shows the page's network traffic: 0 requests and 0 B for your data.
How to check it yourself, step by step
What you can check yourself
Open your browser's developer tools on the Network tab before you drop a file: while the tool works you will see no request carrying your data, and the counter under every result shows the page's own measurement.
The site sets no cookies, so there is no cookie banner. Anonymous usage counts and error reports without file names are the only things that leave the page, as the privacy policy describes.
Every change goes through thousands of automated tests in three browser engines, including a guard that fails a test if a single byte of a file leaves the page.
Frequently asked questions
- Why did my cut move a little?
- Without re-encoding, a video can only start on a keyframe (a full picture), which phones and cameras store every second or two. The cut then starts at the keyframe just before the time you chose, and the result line says by how much. Tick Precise cut to re-encode and start exactly on your frame; it takes longer and the picture is encoded again.
- Can I keep several parts, or cut one out of the middle?
- Yes. Add up to 20 parts. With Keep, the parts are joined in time order; with Remove, they are cut out and what is left is joined.
- Does it lose quality?
- Not by default: the picture and the sound are copied packet for packet. Only Precise cut re-encodes, at about the source's own bitrate.
- Which formats work?
- MP4, MOV, M4V, WebM and MKV. The result keeps the format of your video (a MOV comes out as MP4, which holds the same streams), or you choose MP4, WebM or MKV. A frame-exact cut needs a browser that can encode video: a current Chrome, Edge, Firefox or Safari.
- Is my video uploaded?
- No. Your browser reads it in pieces and makes the result on your device; the counter under the result shows 0 bytes sent.
- Can I trim a video on my iPhone or Android phone?
- Yes, in the browser, without an app. A copied cut is quick even on a long clip; Precise cut re-encodes and takes longer on a phone.
- Does trimming make the file smaller?
- In proportion to what you keep: half the length, about half the size. For a size limit in MB, trim first and then use Compress video.
- How do I cut the first few seconds?
- Set one part to keep from, say, 5 seconds to the end, or switch to Remove the parts and mark 0 to 5. Both give the same result.
- Will the sound stay in sync?
- Yes. Picture and sound are copied together with their timing, and a precise cut re-encodes both from the same point.
- Can I join the kept parts into one video?
- Yes. Keep the parts joins them in time order into a single file. To join separate videos instead, use Merge videos.
Install it as an app
Chrome, Edge and Android browsers offer to install this site from the address bar or the menu; on iPhone use Share, then Add to Home Screen. It opens like an app, keeps working offline and still processes everything on your device.
