Compress GIF files
Click or drop a GIF file here
GIF Compressor shrinks your animated GIF's file size while keeping the animation intact, using gifsicle compiled to WebAssembly (gifsicle-wasm-browser) entirely in your browser — nothing is uploaded to a server. The quality slider controls gifsicle's lossy compression level: higher quality applies less lossy compression (relying mainly on lossless optimization), while lower quality allows more aggressive lossy compression for a smaller file.
Does this reduce my GIF's file size while keeping it animated?
Yes — it uses gifsicle's real GIF optimization and lossy compression, and the output stays a fully animated GIF.
How much can I expect to save?
It depends heavily on the source GIF and the quality setting — simple, few-color animations may shrink only modestly since they're already efficient, while complex or noisy ones can shrink substantially at lower quality settings.
Will lower quality settings look noticeably worse?
Yes, at more aggressive settings — gifsicle's lossy compression can introduce visible speckled noise, especially on flat-color areas. If that's noticeable, raise the quality slider and re-compress.
Is GIF Compressor free to use?
Yes, it's completely free with no signup and no limit on how many files you can process.
Is my file uploaded anywhere?
No. Processing happens entirely in your browser via WebAssembly — your file is never uploaded to a server.
