GIF Compressor
Make an animated GIF smaller without uploading it — and see exactly how much you saved.
Nothing is uploaded. The GIF is taken apart and rebuilt by your own browser.
🔒 Runs entirely in your browser — nothing you type is uploaded or stored on a server.
Drop in an animated GIF that is too big to send, post or attach, choose how hard to squeeze it, and press Compress. The page shows the size before and after and the percentage saved, and plays the result so you can check it still looks right before you download it.
Also on Txtset: build a GIF from pictures · turn a video clip into a GIF.
Four things make a GIF smaller, and you choose which to use. Fewer colours (a GIF can have up to 256; 64 is often indistinguishable). A smaller size — half the width is a quarter of the pixels. Fewer frames, with the time of each dropped frame added to the one before it so the animation plays at the same speed. And the one that costs nothing: after the first frame only the part of the picture that changed is stored. Many GIFs out there store every frame whole, and this alone can shrink them a lot.
If your settings would make the file bigger — it happens with a GIF that was already well optimised — the page says so and the download gives you back your original rather than a worse copy. Transparent GIFs keep their transparency.
Nothing is uploaded: the GIF is taken apart and rebuilt by this page, in your browser. To shrink a PNG, JPEG or WebP instead, use the Image Compressor.

Examples
Often under 2 MB at 64 colours, because the still parts of the screen are stored once.
Half the frames at the same playing speed — roughly half the size.
If nothing helps, the page says so and hands back your original.
