Keep it sharp or keep it small
Fast when possible
If the video already fits the new format, it is repackaged without re-encoding, which takes seconds.
Resolution
Scale down to 1080p, 720p or 480p to make files smaller for sharing.
GIF settings
Choose width, frame rate and length. GIFs are capped at 30 seconds to keep them usable.
Why does video take longer than images?
Every frame is decoded and encoded again on your device. Speed depends on your hardware. When a video only needs a new container, such as some MOV to MP4 conversions, it finishes in seconds.
Which browsers can convert video?
Converting between MP4, WEBM, MOV and MKV needs WebCodecs, which current versions of Chrome, Edge, Safari and desktop Firefox support. Making GIFs and extracting MP3 works in more browsers.
How long can a GIF be?
Up to 30 seconds. GIFs store every frame as a full image, so long clips quickly reach tens of megabytes. For anything longer, MP4 is the better choice.
Will my video lose quality?
With Best available, the original video is kept whenever the new format allows it, and otherwise it is encoded at high quality. Balanced and Smaller file trade some detail for size.
