Twitter and X have specific rules for GIF uploads. Our tool sticks to them by default, but here's the full picture:
Up to 15 MB on desktop, 5 MB on mobile. Auto-optimize aims for under 5 MB so your GIF works everywhere.
Maximum 2 minutes 20 seconds. Loops under 6 seconds tend to get the most engagement.
506x506 (square), 1280x720 (landscape), 720x1280 (portrait) all play well. Twitter auto-scales other sizes.
Twitter converts uploaded GIFs to MP4 server-side. That's why our downloader returns MP4 by default.
Convert MP4, MOV, WebM and AVI clips into Twitter-optimized GIFs with frame-accurate trimming.
Stitch multiple photos into an animated GIF with adjustable frame delay and loop count.
One-click sizing for square, landscape and portrait formats that match Twitter's recommended dimensions.
Generate all three Twitter formats at once and download them as a ZIP archive.
Smart compression keeps your file under Twitter's 5 MB mobile limit without killing quality.
Theme follows your system preference - or toggle manually from the header.
The best Twitter GIFs are short, punchy and loop seamlessly. A few things that actually move the needle:
Working on a YouTube angle too? Pair this with the YouTube Thumbnail Maker or grab audio with Twitter to MP3.
You upload a .gif file, and Twitter accepts it - but server-side Twitter converts every GIF to MP4 for playback. That's normal and expected. Your GIF still behaves like a GIF visually (autoplays, loops, no sound), it's just delivered as MP4 to viewers. See our Twitter GIF Downloader page for the full explanation.
Twitter allows up to 15 MB from desktop and 5 MB from mobile. We default to auto-optimization that targets under 5 MB so your GIF works on every device. If you need even smaller, run it through Compress GIF afterwards.
Yes - use the Twitter GIF Downloader to grab the MP4 from a tweet, then upload it here to remake it with new dimensions, trimming or effects.
Up to 50 images per GIF in a single batch. For more creative control over images-to-GIF flow, the general GIF Maker also supports drag reordering.
Square (506x506) is the universal safe choice. Landscape (1280x720) looks best embedded in desktop timelines. Portrait (720x1280) is ideal if your audience is mostly on mobile and you want to dominate the screen. The All Twitter Sizes option creates a ZIP with all three so you can A/B test.
