Convert video clips into high-quality animated GIFs — fast, free, and entirely in your browser
GIFs are limited to 256 colors per frame. Videos with gradients, subtle shadows, or photographic content may show color banding. For best visual quality, choose clips with flat colors, clear contrast, and minimal gradients — which is why GIFs excel at cartoon-style and text-overlay content.
GIF file size = width × height × frame count × color complexity. Halving the width reduces file size by roughly 4×. Reducing frame rate from 30 to 15 fps cuts size nearly in half. Every dimension matters — a 240px-wide GIF can be 10-20× smaller than a 720px-wide one with the same content.
All GIFs created here loop infinitely by default. Most platforms (Twitter, Facebook, Slack, Discord) auto-play and loop GIFs seamlessly. For email signatures or presentations, a well-optimized GIF under 1MB ensures smooth playback across all clients without bloating your message size.
