How it works

How to trim a video, free, in three steps.

  1. 1

    Drop in your video or audio

    MP4, MOV, WebM, MP3, WAV or M4A, of any length. It opens in your browser, ready to play; nothing is uploaded.

  2. 2

    Set the start and the end

    Drag the handles on the timeline, play the part you're keeping, or type the exact times. Set a point to wherever the playhead is with one click.

  3. 3

    Download the trimmed file

    Lossless, the default, doesn't re-encode at all: it's instant, and the quality is the original's. Exact re-encodes the picture so the clip starts on your very frame in every app.

Why this one

Free, with nothing held back, and nothing uploaded.

Lossless by default

Lossless mode copies the original video and sound without re-encoding a single frame. It's done in a second, even for a long 4K video, and nothing changes.

Frame-exact when you need it

Exact mode re-encodes the picture at high quality so the trim starts and ends on precisely the frames you picked.

Any length, any size

The file is read from your disk as it's needed, so long recordings and multi-gigabyte camera files trim as easily as a short clip.

No watermark, no account

The trimmed file is yours as it is: no logo, no sign-up, nothing uploaded and no limit on how many you trim.

Your file is opened and processed by your own browser. It is never sent to a server, so it stays private, and there’s no upload to wait for.

Trimming a video online, without the catches

Most online trimmers upload your video to a server, cap its size, and add a watermark unless you pay. This one opens the video in your own browser instead, so there's no upload to wait for, no size cap of ours and nothing added to the file.

Choose Lossless and the video is cut without being re-encoded, so it's instant and its quality is untouched. Choose Exact and the picture is re-encoded at high quality so the clip starts and ends on exactly the frames you chose.

Rescroll

Trimming the ends is one cut. A whole edit is hundreds.

Rescroll's AI video editor takes the raw recording and makes every cut for you: the false starts, the retakes, the pauses and the filler words, then adds captions and graphics.

Questions

The video trimmer: your questions, answered.

How do I trim a video for free without a watermark?

Drop the video on this page, drag the start and end handles (or type the times), and press Trim. The trimmed MP4 downloads with no watermark, no account and no upload.

Can I trim an iPhone video (MOV)?

Yes. iPhone MOV files, including HEVC and HDR video, open in Chrome, Edge and Safari. The trimmed file downloads as an MP4.

What's the difference between exact and lossless trimming?

A video is stored in groups of frames that each start with a key frame, so cutting without re-encoding can only start on one. Lossless mode copies those groups untouched and marks your start point, which most players honor exactly; a few apps ignore the mark and show the second or so before it. Exact mode re-encodes the picture so the file starts on your frame everywhere.

Does trimming reduce the video quality?

Lossless mode doesn't touch the quality at all: the video is copied, not re-encoded. Exact mode re-encodes the picture at a high quality setting where the difference is very hard to see.

Is this video trimmer really free?

Yes. There's no price, no trial, no account and no limit on how many files you do. The video trimmer runs on your own device, in your browser, so it costs us nothing to run and we don't charge for it.

Does it add a watermark?

No. The file you download has no watermark, no logo and no intro or outro added. It's your file, changed only in the way you asked.

Is my video or audio uploaded anywhere?

No. The file is opened and processed by your browser, on your device, and never sent to a server: not to us, not to anyone. You can check: watch the Network tab of your browser's developer tools while it works, and you'll see the file is never sent anywhere.

How big a file can it handle?

There's no file size limit of ours. Files of several gigabytes work, because the file is read from your disk as it's needed rather than loaded all at once. What sets the pace is your device: a long 4K video takes longer on an older laptop than on a new one.

Which browsers does it work in?

Current versions of Chrome, Edge and Safari, and Firefox on a computer: any browser with the WebCodecs API for encoding video and sound. Some files, like iPhone HEVC video, need Chrome, Edge or Safari to decode. A computer is much faster than a phone for long videos.
