About Animated GIF
GIF (Graphics Interchange Format) has been the web's animated image format since 1987. Despite its age and severe limitations — 256 colours, no audio, enormous file sizes — GIF remains ubiquitous for short clips, memes, reactions, and UI animations. Modern alternatives like WebP and AVIF are technically superior, but GIF's universal support keeps it relevant.

Why privacy matters for file conversion
Most online converters upload your files to remote servers where they may be scanned, stored, or shared. This tool is different — the conversion runs in your browser via WebAssembly or the WebCodecs API. Your files stay on your device. Always.

Frequently asked questions
GIF uses LZW compression on individual frames — it has no inter-frame compression like video codecs. A 10-second GIF can easily be 10-50MB, while the same clip as MP4 might be 500KB.
Drop your video into this converter and select GIF as the output. The converter automatically adjusts frame rate and resolution for reasonable file sizes. For best results, keep clips under 10 seconds.
Yes, completely free with no file limits. The conversion engine runs directly in your browser — we have zero server costs for processing, so we can offer it at no charge.
Your file never leaves your device. The conversion engine runs 100% in your browser using WebAssembly or the WebCodecs API. We have no access to your files — no uploads, no logs, no data collection whatsoever.
On desktop browsers (Chrome, Firefox, Edge) files up to 500 MB convert reliably. On Safari (macOS) the practical limit is around 200 MB. On iPhone and iPad, keep files under 50 MB — iOS enforces tight memory limits for browser-based processing.
On your first visit, the browser downloads the conversion engine (24–50 MB depending on which backend is used). This is cached locally, so subsequent conversions load much faster.
Chrome, Edge, and Brave use hardware-accelerated WebCodecs when the format is supported — this is 5–10× faster than software encoding. For unsupported formats the tool falls back to ffmpeg.wasm, where Firefox typically performs best.
