How to Convert Video to GIF This free tool converts videos into animated GIFs without uploading anything. Powered by FFmpeg compiled to WebAssembly, all processing runs on your own device — fast, private and free. What is a GIF and when should you use one? GIF is a widely supported animated image format. It is perfect for short loops, reaction clips, tutorials and product demos that need to autoplay everywhere without a video player. Because GIFs are uncompressed compared to modern video, keeping them short and low-resolution keeps the file size reasonable. How the converter works Upload a video, choose your settings and click Create GIF. In quality mode you pick the FPS, width and color count directly. In target-size mode the tool automatically lowers FPS, resolution and colors across several passes until the GIF fits under your chosen limit. Tips for smaller, better GIFs Trim to the exact segment you need — length has the biggest impact on size. Lower the FPS to 10–15; most GIFs look great and shrink dramatically. Reduce the width for social media or chat where large GIFs are unnecessary. Fewer colors and no dithering produce the smallest files for flat graphics. Is it private? Yes. Your video is processed locally with WebAssembly and never leaves your browser. Nothing is stored or transmitted to our servers. Frequently Asked Questions Is there a file size or length limit? There is no hard server limit because everything runs locally. Very large or long videos use more memory, so trimming to the part you need is recommended. Which video formats are supported? MP4, WebM, MOV, MKV, AVI, FLV and WMV all work in most modern browsers. How does target file size work? The tool encodes the GIF, checks the resulting size and, if it is too large, automatically lowers FPS, resolution and color count and re-encodes until it fits under your limit. Why is my GIF still large? GIFs are inefficient for long or high-motion clips. Shorten the duration, lower the FPS, reduce the width, or lower the color count for the biggest savings. Does it work on mobile? Yes, but converting is memory-intensive. On phones, use shorter clips and smaller resolutions for the best results.
