Use GIF for universal short loops
GIF is ideal when an animation needs to appear like an image: chat reactions, forum posts, simple stickers, and compact embeds. It loops automatically and is recognized almost everywhere.
The tradeoff is size and color. Keep dimensions modest, export one short cycle, and avoid noisy photographic backgrounds when a small file matters.
Use WebM for efficient browser video
WebM preserves more color and usually produces a much smaller file than GIF. It is a good default for modern web publishing and works directly with browser recording APIs.
Because the recorder captures the same canvas used for preview, the export remains local and closely matches what you saw in the studio.
Use MP4 when the browser exposes it
MP4 has broad playback support on social platforms, but browser-side encoding is not equally available everywhere. Purupuru Maker enables it only when MediaRecorder reports a compatible MP4 type.
If the MP4 button is unavailable, export WebM. Many platforms accept it directly, and a later conversion does not require repainting your animation.
