How to convert MP4 to GIF
1. Drop one MP4 or WebM. A WAV, a MOV or a photo is refused here. 2. Set the start if the GIF should begin later than 0:00. 3. Leave the length at 5 seconds, or type a shorter one. The page stops at the limit shown next to the field. 4. Leave 480 px and 12 frames per second, or pick a smaller width when the file must be lighter. 5. Press “Create GIF” and wait for the download.
FFmpeg, compiled to WebAssembly, samples the frames, builds a palette for the clip and dithers the result. The first visit downloads that engine. Later visits reuse the browser cache.
Same GIF builder, a shorter list of files
Video to GIF accepts MOV and MKV as well. This address is for people who already know the file is MP4 or WebM, which is what phones and screen recorders usually save. A WebM is accepted. It is re encoded into a GIF, so the download is not a WebM.
GIF is an old format and grows fast. Three to six seconds at 480 px and 12 fps is a practical start. There is no audio in a GIF.
The clip stays in this tab
Encoding uses one CPU thread, so a few seconds of video can take longer than they play. Leave the tab open until the download appears. GustKit does not fetch a video from a link. Close the tab and the file is gone.
How to check the GIF
1. Open the download. It should loop and it should have no sound. 2. The first frames should match the start time you set. 3. If a MOV was accepted, you opened Video to GIF.
Video to GIF accepts more containers. This page runs the same FFmpeg palette and only reads MP4 and WebM. Nothing is uploaded.
