MP4 video format is far more efficient than GIF. A 10MB GIF typically becomes just 1-2MB as MP4 — an 80-90% size reduction. MP4 supports smoother frame rates, better colors (16 million vs GIF's 256), and virtually all platforms support MP4 playback natively.
Yes. The generated MP4 includes loop metadata by default. Use the HTML5 video tag's loop attribute on web pages, and it will auto-loop on social media uploads too — a perfect GIF replacement.
You can choose output quality. High quality mode (CRF 18) is nearly lossless with slightly larger files; default mode (CRF 23) offers good quality with smaller files. Compared to GIF's 256-color palette, MP4's 16 million colors can render richer visuals.
Transparent GIFs (transparency becomes black background), multi-frame GIFs, and variable frame rates are all supported. For very large GIFs (>50MB), consider compressing locally first. FFmpeg.wasm runs client-side — first load may take a few seconds to download the WASM binary.
