How do I turn a video into a GIF?
Drop the file, pick the range, set frame rate and width, export. The frames are decoded in your browser and assembled into a GIF right there — nothing is uploaded. A GIF plays automatically everywhere, without a player and without sound, which is why it is at home in chats, issue trackers and documentation.
Why is the GIF bigger than the video?
Because GIF has no motion compression. The format stores every frame on its own, and the GIF89a specification by CompuServe (1989) allows at most 256 colours per frame from a palette. Modern video codecs, by contrast, only store the differences between consecutive frames — which is why a clip as MP4 often weighs a tenth of what it needs as a GIF.
Which settings keep the file small?
Three levers, in this order:
- Width: half the width means roughly a quarter of the data, because pixel count falls with the square.
- Frame rate: 10 to 12 frames per second still look fluid in short loops; 15 is the sensible ceiling.
- Length: duration multiplies everything else. Under five seconds almost every GIF stays manageable.
Why do the colours look banded?
Because of the 256-colour limit. A photographic scene with gradients, skin tones or dark areas has to be reduced to that palette, and that produces visible banding. Screen recordings of interfaces usually look perfect, because they consist of few, clearly separated colours to begin with — the classic use case for GIF.
When should you not use a GIF?
For anything longer than a few seconds or anything that has to stay sharp. An MP4 or WebM is then smaller, crisper and also plays everywhere — just inside a player. And GIF fundamentally cannot carry sound: the audio track is lost in the conversion, which this tool does not hide. Because every frame sits in memory on its own, long or large GIFs quickly hit the browser's limits; trimming and lowering the width help more than any other setting.
