No. ffmpeg.wasm runs inside your browser; videos and outputs never leave your device.

GIF is limited to 256 colors. Generating an optimal palette first (palettegen) and applying it (paletteuse) gives much better color reproduction than the single-pass default.

The GIF is huge — what can I do?

Lower fps (e.g. 10 → 8), reduce width, or trim to a shorter range. GIF is inherently inefficient.

Why GIF instead of MP4 / WebM?

GIF still wins on compatibility (plays / autoplays nearly everywhere). For size, MP4 / WebM are far smaller.

GIF to MP4 converter — H.264 cuts file size to 1/5–1/10

Convert animated GIFs to H.264/AAC MP4 videos. GIFs balloon quickly; MP4 (H.264) typically shrinks the file to 1/5–1/10 the size and plays inline on X (Twitter), Bluesky, Discord and other social platforms. ffmpeg.wasm runs entirely in your browser — GIFs never leave your device. Supports batch processing and a single ZIP download.
