Video Converter
Change a video's format, for example an iPhone MOV or a WebM screen recording to MP4. When the new format can hold the video as it is, it's copied without re-encoding, so the conversion takes seconds and loses no quality.

Good to know
No upload
The video is converted by your browser and never leaves your device.
Copies when it can
If the video and sound already suit the new format, they're copied as they are: fast, with no quality loss.
MP4 that plays everywhere
For MP4 and MOV, other video is re-encoded to H.264 with AAC sound, which every phone and website plays.
Four formats
Convert to MP4, WebM, MOV or MKV. The page says before you start whether the video will be copied or re-encoded.
Frequently asked questions
Is my video uploaded?
No. The conversion runs in your browser, and your video never leaves your device.
Why was my conversion so fast?
Because the video was copied, not re-encoded. MOV and MP4 can hold the same H.264 video, for example, so changing an iPhone MOV to MP4 often only rewrites the file around the same video and takes a few seconds.
Does converting lower the quality?
Copied video and sound keep exactly the same quality. When re-encoding is needed, the bitrate is set from the original video's, so it looks the same for most clips, but it isn't a perfect copy. Converting to H.264 can make the file larger, because H.264 needs more space than H.265, VP9 or AV1 for the same quality.
My iPhone video is H.265 (HEVC). What happens?
For MP4 and MOV it's re-encoded to H.264 by default, so it plays on Windows, Android and websites that don't support HEVC. Turn on "Keep H.265 / VP9 / AV1 video" to copy it instead, which is faster but less compatible. Opening HEVC needs a device that can decode it.
Which format should I choose?
MP4 for sharing, uploading and playing on phones. WebM for websites that ask for it. MOV for Apple editing apps. MKV if you want to keep every original track as it is.
