Frequently asked questions
Will the quality get worse?
Not in Fast mode: the video data is copied unchanged. Most compatible re-encodes to H.264, which can change the quality slightly.
Why doesn’t the MP4 play on my Windows PC?
iPhone videos are often HEVC. Fast mode keeps HEVC, which some Windows PCs cannot play without an extra codec. Choose Most compatible to get H.264.
Does it work on my phone?
It depends on your browser’s support for video encoding. H.264 encoding works in current Chrome and Edge on computers; in Safari, Firefox and on phones it varies. If your browser can’t do it, the tool tells you clearly.
Is my video uploaded?
No. It is processed in your browser on this device; nothing is sent to a server.
