Choose one video, up to 10 minutes and about 2 GB: MOV, WebM, MKV or an MP4 that won’t play somewhere. You get an MP4 with H.264 picture and AAC sound, the kind phones, computers and apps expect.
When the picture or sound is already the right kind, it is copied exactly, with no loss of quality. Otherwise it is converted, and very large pictures are saved at up to 1080p. Some videos can’t be read by this browser; you’ll be told before any work starts.

Questions
Which formats can I convert?
MOV (including iPhone videos), WebM, MKV, and MP4 files that won’t play somewhere. You always get an MP4 with H.264 picture and AAC sound, the kind phones, computers and apps expect. Some videos can’t be read by a browser; you’ll be told before any work starts.
How do I convert MOV to MP4 on iPhone?
Open this page in Safari, tap Add Video and choose the video. iPhone videos are MOV files; tap Convert to MP4, then Save or Share and Save Video.
Does converting lose quality?
When the picture or sound is already the right kind, it is copied as it is. Otherwise it is made again, and very large pictures are saved at up to 1080p.
Can I convert a video to MP3 or GIF?
Not to MP3. For a GIF, use Video to GIF.
Is there a size limit?
One video up to 10 minutes and about 2 GB.
Why is it slow on my phone?
Your phone does the work itself instead of sending the video to a server, so the time depends on your phone and the video’s length. Making a new video can take several minutes on a phone; as a guide, an iPhone 15 took about 5 minutes to merge a 9.6-minute video. Keep the page open until it’s done. Stop and edit lets you go back without losing your settings. A video that only needs copying is done much faster.
Is my video uploaded?
No. Your video is made on your phone or computer and never leaves it, so a big video doesn’t need a fast connection. We only collect anonymous usage counts and error reports, listed on the privacy page.
