What you can do
Video to GIF and MP4 to GIF turn a few seconds of video into a looping GIF with optimised colour palettes. Extract frames saves stills as JPG, PNG or WebP, as a ZIP or a single contact sheet. Video to vertical reframes 16:9 footage to 9:16, 4:5 or 1:1 with a blurred background, a crop or colour bars, keeping the audio.
Converting between video formats
The MOV to MP4, MKV to MP4 and WebM to MP4 pages, and the converter on the home page, change a video’s format inside your browser. When the video and audio already suit the new format they are copied without re-encoding, so nothing is lost; otherwise your browser’s own encoder re-encodes them. Older formats such as AVI, WMV and FLV are opened with FFmpeg compiled to WebAssembly, which downloads once on first use.
