Free video editor
Cut out the parts you don’t want, speed the video up or slow it down, and turn the sound up or down on any part. It keeps its format and quality, and nothing is uploaded.
Runs on your device. Files are never uploaded.
Your browser can’t show this format, so there is no picture here. You can still cut it by the times on the timeline.
Move the white line to a spot and press Cut here. Each cut makes a new part. Pick a part to delete it or change its volume.
How to use it
- Pick a video (MP4, MOV, WebM, MKV…).
- Move to a spot and press Cut here. Each cut makes a new part. Press the bin on a part to delete it, or pick a part and move its volume slider.
- Choose a speed if you want one, press Play to check the result, then Save video and download it.
Cut out a part of a video
Everything starts with one tool: Cut here. Move the white line to the spot you want, with the timeline or the buttons that step by a second or a tenth of a second, and press it. A cut doesn’t remove anything. It divides the video into two parts, and each part gets its own bin button.
- Trim the start or the end: one cut, then delete the part you don’t want.
- Remove something from the middle: one cut where it starts, one where it ends, then delete the part between them.
Deleted parts stay on the timeline, striped, and Play skips over them, so you can watch the join before you save. Press the arrow on a deleted part to bring it back. To move a cut, drag it. To remove a cut, click it.
Turn the volume up or down on one part
Pick any part and move its slider, from mute up to 300%. It suits a quiet speaker in the middle of an interview, a loud bang in a home video, or a stretch of background talk you’d rather mute. Press Play and you hear the new volume right away.
The change between two volumes takes a hundredth of a second, and a cut fades out and in over a few thousandths, so you don’t hear a click at either. Above 100%, the very loudest sounds are rounded off rather than clipped.
Speed up or slow down a video
The Speed menu runs from 0.25× to 10× and applies to the whole saved video, after your cuts. A 10-minute recording at 10× becomes a 1-minute time-lapse. Press Play to watch it at that speed before you save.
The sound changes speed with the picture, but voices keep their normal pitch. If you don’t want the sound at all, press Mute on each part.
What happens to the quality
Quality and Format both start at Same as original. What the tool then has to do depends on your edits.
| Your edit | Picture | Sound |
|---|---|---|
| Volume only | Copied as it is, no loss | Encoded again |
| Any cut | Encoded again at about the original’s data rate | Encoded again |
| A speed other than 1× | Encoded again | Encoded again |
| Another format, or lower quality | Encoded again | Encoded again |
Our test, in Edge on a desktop PC, used a busy 20-second 1080p test pattern. Cutting 5 seconds out at Same as original took about 9 seconds. The result scored 0.98 out of 1 against the original on SSIM, a standard measure of how alike two pictures are, and its data rate was about 16% higher. A volume-only edit left all 600 frames byte-identical.
A cut has to encode the picture again because most frames in a video are stored as changes from the frames before them, so a cut in the wrong place would leave the first moments broken. Encoding again lets the cut land on the exact frame you chose.
Need the file smaller for an app or an email? Cut it here first, then use Compress Video to hit an exact size. A shorter video gets more data per second, so it looks better at the same size.
Check for yourself that nothing is uploaded
- On a computer, open this page and press F12 to open the developer tools, then choose the Network tab.
- Press the clear button in that tab, then drop a video here, cut it and save it.
- Look at the list. An upload would be a request with the size of your file going out, usually marked POST or PUT. There isn’t one.
You will see a small video library fetched from this site. If your browser can’t read or encode the file, about 31 MB also comes in once from cdn.jsdelivr.net. The arrows all point in: your video is read on your device and never sent. The page also loads its ad code from Google. That is a normal download with none of your file in it.
Once the page has opened a first video, you can turn off Wi-Fi and keep editing with your browser’s own encoder.
FAQ
Do I need two cuts to remove something?
Only to remove something from the middle. To trim the start or the end, one cut is enough: it makes two parts, and you delete the one you don’t want.
Does editing lower the quality?
If you only change the volume, the picture is copied as it is, so it loses nothing. A cut has to encode the picture again to land on the exact frame. At Same as original it aims for about the original’s data rate.
Can I make a quiet part louder?
Yes, up to 300%. Pick the part and move its volume slider, then press Play to hear it. Above 100%, the loudest sounds are rounded off so they don’t crackle, but very high settings can still sound harsh.
Can I mute one part of a video?
Yes. Cut around the part, pick it and press Mute. The picture carries on and the rest of the sound is not touched.
Can I speed up or slow down a video?
Yes, anywhere from 0.25× to 10×. The speed applies to the whole saved video, and voices keep their normal pitch. Sped-up video drops frames so it stays at the original frame rate, while slowed video shows each frame for longer, so very slow motion can look jerky. At very high speeds, some browsers go silent in the preview, but the saved file still has its sound.
Which format will I get?
The same one you opened: an MP4 stays an MP4 and a MOV stays a MOV. You can also choose MP4, MOV, WebM or MKV. Older formats such as AVI are saved as MP4.
Is there a length or size limit?
No fixed limit. Your device does the work, so long videos take longer and very large ones can run out of memory on phones and older computers.
