About this tool

Every GIF uploaded to X gets converted to a looping MP4 video on the spot. It's not a trick — MP4 files are roughly 10× smaller than real .gif files at the same quality, which is why your feed loads fast.

So when you save a "GIF" from X, an MP4 is the original, full-quality file — it loops, it plays everywhere (iMessage, WhatsApp, Discord, every video editor), and it looks better than any .gif conversion would. For the places that strictly require GIF format — Slack emoji, GIF keyboards, forums — use the Convert to real .gif button: it converts in your own browser with a proper color palette, and nothing gets uploaded to any server.
