Resize GIFs for Twitter/X

Twitter (now X) is one of the largest platforms for GIF sharing, but it handles GIFs differently than most sites. When you upload a GIF, Twitter converts it to MP4 video for bandwidth efficiency. The conversion process works best when the source GIF is already at an optimal size: 480x480 pixels for square content, or 480px wide for other aspect ratios.

This tool resizes your animated GIF to 480x480, the optimal dimension for Twitter inline display. All processing happens in your browser with no server upload.

Twitter GIF Limits

Twitter accepts GIFs up to 15MB and 1280x1080 pixels. Files over 5MB may take longer to process. For the fastest upload and best display quality, keep your GIFs under 5MB at 480px dimensions. After resizing, use our GIF compressor to optimize the file size.

For reaction GIFs and memes, square format (480x480) works best because it gets the largest display area in the timeline. For widescreen content like screen recordings, use 480px width with proportional height. Twitter's feed layout is designed for vertical scrolling, so square and portrait formats generally perform better than landscape.

Frequently Asked Questions

What is the best GIF size for Twitter?

Twitter accepts GIFs up to 15MB and 1280x1080 pixels. However, Twitter automatically converts GIFs to MP4 video. Pre-sizing to 480x480 gives Twitter an optimally-sized source, avoiding unnecessary downscaling that can introduce artifacts.

Does Twitter convert GIFs to video?

Yes. Twitter converts all uploaded GIFs to MP4 video for bandwidth efficiency. You will see it play as a video with a GIF badge. Pre-optimizing the dimensions gives Twitter a cleaner source to work with, resulting in better final quality.

Why 480x480 and not larger?

Twitter displays GIFs in the feed at roughly 480px wide on desktop and smaller on mobile. Uploading a 1920px-wide GIF means Twitter must downscale it, which can introduce compression artifacts. Starting at 480x480 means less processing and better visual fidelity.

What about non-square GIFs?

Twitter supports any aspect ratio, but square (1:1) GIFs get the most display real estate in the feed. Widescreen GIFs are displayed smaller. If your content is not square, consider 480px wide with proportional height.
