Questions
Is my video uploaded?
No. Everything happens in your browser, and this site has no way to receive your video.
Can I check for myself that nothing is uploaded?
Yes. Open this page, then disconnect from the internet. With the connection off, you can still choose a file and save the result.
For the first few seconds after the page opens, it is still fetching the parts it needs, so wait a moment before disconnecting. Reloading the page needs the connection again.
Note that some of the other tools on this site fetch extra parts after reading your file — for example, the character tables needed to show a PDF that does not embed its fonts. If you have a data-saving setting turned on, nothing is fetched ahead of time either, so a connection is needed then too.
Which formats can I convert to?
- MP4 (H.264) — plays on anything. Choose this if you are unsure.
- WebM (VP9) — smaller than MP4 at the same quality. Plays in browsers on computers and phones.
- WebM (AV1) — the smallest files, but conversion takes longer and fewer devices support it.
Which formats can I open?
MP4 and MOV. Most phone recordings use these. The video inside can be H.264, H.265, VP9 or AV1, as far as your browser supports it.
How do I make the file smaller?
Resolution matters most — going from 1080p to 720p more than halves the size. Setting the quality to "Smaller file" reduces it further, and WebM (VP9) helps too. The expected size is shown before you convert, so try a few combinations.
Does the quality drop?
Yes. Changing the format means compressing the video again. Resolutions larger than the original are not offered, because upscaling does not improve quality.
How long does it take?
It depends on the length and resolution — roughly one to two minutes for a minute of 1080p. AV1 takes longer. You can press "Stop" at any time.
I only want part of the video
That is what the video trimmer is for; cutting only the end is lossless.
How much can I use for free? Are there limits?
Every feature, as many times as you like. There is no daily cap, nothing changes if you sign up, and you will never be asked to pay later.
There is a limit on file size, but it comes from what a browser can handle at once. The work runs on your own device, so there is nothing for us to meter. The exact figures are in the other answers on this page.
Does this work on a phone?
Yes. Please keep the following in mind.
- Large videos can stop partway. A few hundred MB is the rough limit. A computer has more room.
- Keep this page open while it works. Switching to another app stops it.
- Some formats, such as AV1, cannot be made on an iPhone. Choose another format if it fails.
- Saved files go to the Files app. To put them in Photos, use "Share" next to the download button.
