Trim & cut
Cut a clip out of your video without uploading it
Only need ten seconds of a longer recording? Enter a start and end time and this tool cuts exactly that section out of your video, saving it as a clean MP4. It runs entirely in your browser using WebAssembly, so your file never leaves your device — no slow upload, no privacy worry.
Choose your video
Click Choose a video and select a file up to 200 MB. It is read locally, so a long recording is ready to work with immediately rather than after an upload.
Enter the start and end time
Type the Start and End in seconds — 5 and 20 keeps the fifteen-second window between them. Decimals are allowed, so 12.5 is a valid time. The end must be later than the start.
Trim and download
Press Trim. After the one-time engine download the cut runs locally and the result appears in a player. Download it and the clip is saved with -trimmed added to your filename, leaving the original untouched.
Times are in seconds, not minutes and seconds
This trips people up often enough to be worth stating plainly: both fields take a plain number of seconds counted from the very beginning of the video. If the moment you want starts at one minute thirty, enter 90 — not 1:30, and not 1.30. For a clip at two minutes fifteen, that is 135. The arithmetic is simple enough once you know: multiply the minutes by sixty and add the remaining seconds. Decimals are accepted for finer control, so 90.5 is half a second past the minute-and-a-half mark, which is often enough precision to catch or avoid a specific word. A quick way to find your numbers is to open the video in any player, note the timestamps where the section you want begins and ends, and convert both to seconds before typing them in.
The cut is frame-accurate, not approximate
Many fast trimmers copy the video stream without re-encoding it, which is nearly instant but can only cut at keyframes — points that may be several seconds apart. That is why those tools often hand back a clip that starts a second or two before you asked, or opens on a frozen or garbled frame. This tool decodes the video and re-encodes the section you asked for, so the cut lands on exactly the times you typed and the first frame is clean. The cost is time: a real encode is much slower than a stream copy. It is the right trade when precision matters, which for trimming it almost always does.
What the trimmed file looks like
The output is MP4 with H.264 video at CRF 23 and AAC audio, keeping your original resolution and frame rate. CRF 23 is a quality-preserving setting, so the clip should look essentially the same as the source. Audio is kept and stays in sync with the picture. Because you are keeping less of the video, the file is proportionally smaller — cutting a three-minute recording down to thirty seconds gives you roughly a sixth of the size. This makes trimming the most effective first move whenever a file is too large to send, and it costs no visible quality at all, unlike compressing the whole thing.
Trim first, then use the other tools
Trimming pairs well with everything else here, and doing it first usually saves time. The GIF maker always converts from the start of a file, so trimming is how you make a GIF of a moment partway through a longer video. The compressor works faster on a shorter file and produces a much smaller result. Muting and converting both re-encode the whole clip, so cutting away the parts you do not need means less work for your device. And because a trimmed file is smaller, it is far less likely to run into the browser memory limits that cause long 4K videos to fail in the heavier tools.
How long trimming takes, and what can go wrong
Encoding time depends on the length of the section you keep rather than the length of the source, so pulling ten seconds out of an hour-long recording is quick even though the file is large. Expect roughly a few minutes per minute of 1080p output on a laptop, slower on a phone and slower again at 4K. If you get an error, check the times first — an end that is earlier than or equal to the start is rejected, and so is an end time past the actual duration of the video. Files over 200 MB are refused up front. If the trim fails on a very large 4K source, the browser has most likely run out of memory for the tab; converting the video to a smaller format first, or trying on a desktop machine, is the usual way through.
Private by design
Because trimming happens on your device, your video is never sent anywhere and nothing is stored. This is particularly worth noting for trimming, since the whole point is often that only part of the recording should be seen by anyone — you are cutting out the section before the meeting started, the part with someone's address in it, or footage of people who did not agree to be filmed. Uploading the full video to a server to remove those things would defeat the exercise. Here the untrimmed file never leaves your device. It works on desktop and modern mobile browsers, and the engine downloads once on first use.
Frequently asked questions
Answers to the most common questions about using these free video & audio tools.
Enter the times in seconds. For example, to keep the part from 5 seconds to 20 seconds, set Start to 5 and End to 20. The end must be after the start.
