Drag and drop it into the compressor. Free to start, no signup, no install; it works in your browser.
The live preview shows the compressed file size automatically and compares it side by side with the original. Adjust the preset, undo, or jump back to an earlier edit until the readout hits your number.
No watermark. Before exporting you can also crop, resize, cut, change speed, reduce colors, or edit individual frames in the same editor.
Platforms enforce byte caps, not quality standards, so "smaller" isn't enough; you need a specific number. Because the file-size readout updates as you change presets, you can land on 512KB directly instead of exporting, checking, and re-exporting. The demo above took tennis-balls.gif from 702KB to 226KB, a 68% cut, at preset 75. Chasing a looser limit? Use the same editor to compress GIF to 1MB.
Discord caps custom emotes at 256KB and regular uploads at 8MB. To compress GIFs for Discord, pick a preset and watch the readout drop under the cap you need. For emotes, compress GIF to 256KB on the dedicated size page. A GIF compressor for Discord is really an exact-size compressor: know the cap, hit the number.
GIF encodes every frame with lossless Lempel-Ziv-Welch (LZW) compression, which packs repeated pixel patterns without discarding data. Each frame also carries a color palette of up to 256 colors, and a few seconds of animation means dozens of frames, so GIF file sizes climb far faster than MP4. To reduce GIF file size, a compressor shrinks the work LZW has to encode: it cuts the number of colors per frame, drops repeated frames, and lowers the frame rate. Lossy LZW goes further, discarding fine pixel detail for extra savings.
Two levers matter most. Resizing shrinks the pixel dimensions of every frame; keep the aspect ratio so nothing distorts. Lowering the frame rate keeps the dimensions but drops frames, so motion gets slightly steppier. Screen recordings usually survive a resize well, while fast reaction GIFs tolerate a lower frame rate better.
Start with a preset, then adjust each file. Crop, resize, cut, change speed, colors and frames in one editor.
Switch between tools without starting over. Your preview, file size and editing controls stay in view.
Preview each change with an automatic file-size readout. Undo any edit or compare the result with your original.
Choose a preset, then adjust colors, frames, dimensions or duration. The live preview shows the resulting file size as you edit.
Check each edit in the live preview and see the file size automatically. Your edit history stays intact as you switch tools.
Start compressing without signing up or installing an app. The free plan adds no watermark.
GIF optimization is rarely a single action. A preset does the heavy compression, then the same editor lets you crop dead space, resize oversized dimensions, cut the loop shorter, change the speed, reduce colors further, and remove duplicate frames, which add size without adding motion.
Because it's one editor rather than a chain of single-purpose tools, you optimize your GIF in one pass instead of re-exporting between steps. Starting from video? Convert up to 10 seconds of MP4 into a GIF, then run it through the same GIF optimizer workflow.
