Convert animated GIFs to WebM video for dramatic file size savings - typically 3 to 10 times smaller than the original GIF. WebM uses modern VP9 or VP8 codecs that pack much more efficiently than GIF's palette compression. Going the other way? Use our WebM to GIF tool. For other formats try GIF to MP4 or Compress GIF.

WebM is a modern video format that produces dramatically smaller files than GIF while looking the same or better. A 10 MB GIF typically becomes a 1-2 MB WebM, and the visual quality is often higher because WebM uses 24-bit color and modern codecs (VP9 or VP8) instead of GIF's 256-color palette and dated LZW compression.
WebM is supported natively by every modern browser (Chrome, Firefox, Edge, Safari 14+) and is the format Reddit, Discord, and many forums use for animated content. The main downside is that some legacy contexts (older email clients, certain CMS platforms, very old browsers) still require GIF, which is when our WebM to GIF tool comes in handy.
After conversion, upload the WebM to Discord, Reddit, or any modern web platform - they all play natively. Need a fully separate video format? GIF to MP4 works for environments that prefer that.
3-10x smaller files than the original GIF, no visible quality loss.
Pick best compression (VP9) or fastest encoding (VP8).
Fine-tune from near-lossless (15) to maximum compression (50).
Up to 20 GIFs at once, packaged into a single ZIP.
Shrink large GIFs to web-friendly sizes during conversion.
Files auto-delete after 4 hours, no account required.
VP9 is the right answer for almost everyone. It produces files about 30-50% smaller than VP8 at the same visual quality, and every modern browser supports it. Choose VP8 only if you need to support truly old browsers (pre-2014 Chrome, ancient Firefox versions) or if encoding speed matters more than file size to you.
CRF (Constant Rate Factor) tells the encoder how much quality to maintain. Lower CRF = better quality, larger file. For VP9, the useful range is 15 (near-lossless) to 50 (heavy compression artifacts). 30 is the sweet spot for animations - virtually identical to the source GIF visually, with maximum size savings. Drop to 22-25 for high-motion content where compression artifacts would be more visible.
Yes. Discord supports WebM natively in messages and embeds. Reddit hosts video content as WebM internally. Twitter accepts WebM uploads (though it may re-encode them). All modern browsers play WebM via the HTML5 video tag without plugins. If a specific platform rejects WebM, our GIF to MP4 tool is an alternative.
VP9 is a modern codec that does much more analysis per frame than GIF encoding does. The trade-off is that the resulting file is dramatically smaller. If speed matters more than file size, switch to VP8 codec and "Fast" encoding speed - the conversion will run several times faster but the file will be larger.
By default we embed a loop hint that tells browsers to replay the WebM continuously, matching GIF's default behavior. If you uncheck "Loop indefinitely" the WebM plays once. When you embed the WebM in HTML, the loop attribute on the video tag is what actually controls playback: <video src="file.webm" autoplay loop muted></video>.
