Turn an MP4, WebM, or MOV clip into an animated GIF in your browser. Trim, set fps, pick width — no ezgif account, no watermark, no upload. Files stay on your device.
ezgif uploads your file to a third-party server and adds a watermark on the free plan. This tool creates the GIF entirely in your browser — nothing is uploaded, and there is no watermark.
MP4, WebM, MOV, and MKV up to 200 MB. The video codec must be decodable by your browser (H.264 works everywhere; VP8/VP9 work in Chrome and Edge).
GIF uses LZW compression, not the modern video codecs that make MP4 small. A 5-second clip at 10 fps can easily be several megabytes. Keep clips short and width small for a manageable file size.
No. Decoding and GIF encoding both run in the browser using WebCodecs and a JavaScript GIF library. Your file is never sent to a server.
Firefox does not currently support WebCodecs, which is required for decoding the video frames. Use Chrome or Edge for best results.
