Convert animated GIFs to MP4/WebM — 80-90% smaller
100% in your browser — files never leave your device · max 50 MB each
Your browser doesn't support GIF decoding. For best results, use Chrome, Edge, or Safari 17+.
Drop your GIF files
Drag and drop animated .gif files — up to 10 per batch (100 on Pro). Max 50 MB each.
Pick a quality preset
High (8 Mbps) for crisp detail, Balanced (3.5 Mbps) for general use, Small (1.5 Mbps) for maximum savings.
Convert and download
Conversion runs locally via ImageDecoder + MediaRecorder. Download MP4 (or WebM on unsupported browsers) individually or as ZIP.
For Twitter, Discord, and most social platforms, MP4 auto-plays like a GIF but loads 10x faster. Compress more
Modern video codecs (H.264, VP9) crush animated GIFs. A 10 MB GIF typically ends up at 1-2 MB as MP4 with no perceived quality loss.
Uses the browser ImageDecoder + MediaRecorder APIs. No FFmpeg upload, no server. Your GIFs never leave your device.
Convert up to 10 GIFs per batch (100 on Pro). Pick High (8 Mbps), Balanced (3.5 Mbps), or Small (1.5 Mbps) based on your target.
GIF is a 1987 format. It stores each frame as an indexed-palette bitmap and uses a tiny 256-color table per frame. For animations longer than a second or two, this is wildly inefficient — colorful footage can hit 10 MB for a 3-second clip. Modern video codecs (H.264 in MP4, VP9 in WebM) use motion estimation, predictive frames, and entropy coding to compress the same content 10-20x smaller with no visible loss.
Twitter, Discord, Slack, Reddit and most modern sites already convert your uploaded GIF to MP4 silently. Doing it ahead of time saves upload bandwidth, lets you embed the video yourself with controls, and passes through Content Delivery Networks more efficiently.
SammaPix picks MP4 (H.264) where the browser supports encoding it natively. On Chrome, Edge, and modern Safari that's the default. On Firefox the browser may fall back to WebM (VP8/VP9) — still playable in every modern app and 80-90% smaller than the source GIF.
Yes. Every social network treats uploaded MP4 exactly like a GIF for short silent clips: auto-play, loop, muted by default. If you embed it in your own HTML, add autoplay loop muted playsinline on the video tag.
