Free GIF Compressor Online
Animated GIFs are notoriously fat — a 5-second clip can easily weigh in at 5-15 MB at default settings, which exceeds the upload limits on Slack, Discord, Twitter, WhatsApp, and most email systems, and absolutely tanks your website's page load speed if used as decoration. Our free online GIF compressor squeezes oversized animated GIFs down to manageable sizes while preserving the animation. Drop your GIF in, adjust the three compression dials (quality slider, colour-palette count, dimension scaling), and download the optimised version. Each dial trades a different aspect of fidelity for size: quality controls how aggressively each frame is compressed, colour count reduces the palette from the GIF maximum of 256 colours down to as low as 16-32 (most animated content looks fine at 64-128 colours), and dimension scaling shrinks the pixel size of the output (a 1080×1080 GIF scaled to 600×600 typically halves the file size or better). Modern alternatives that compress dramatically better than even the best-optimised GIF: WebP (animated WebP is typically 70-80% smaller than GIF at the same visual quality, supported by all modern browsers since 2020) and MP4/H.264 (video formats compress 90%+ smaller than GIF for the same content). The compressor offers WebP and PNG output alongside optimised GIF — for web use, prefer animated WebP. For genuine video clips that just happen to be saved as GIF, converting to MP4 via our [Video to GIF](/tools/video-to-gif) tool (used in reverse — paste the original video instead of the GIF) gives much better results. Common workflows: shrinking a meme GIF to fit Discord's 8 MB attachment limit, optimising decorative GIFs on a website to improve LCP and CLS scores for SEO, fitting a tutorial screen-recording GIF under email size limits for documentation distribution, reducing GIFs on landing pages where every kilobyte slows mobile users, and trimming WhatsApp-shared GIFs that exceed the platform's recompression limits. Typical results: a 10 MB GIF at default settings drops to 3-4 MB at moderate compression with no visible quality loss, 1.5-2 MB at aggressive compression with mild colour banding, and under 1 MB if you also scale dimensions down. Converting to WebP at the same quality typically lands around 30-40% of the original GIF size. Everything runs in your browser — your GIFs never travel to any server, never get logged. After compression, [Image Compressor](/tools/image-compressor) handles non-animated images, [Video to GIF](/tools/video-to-gif) helps when you want to start from a video file, and [Image Crop](/tools/image-crop) trims GIF dimensions before compression for additional size savings.
How to Use GIF Compressor
Upload GIF
Drag and drop your animated GIF file (or click to browse). The tool detects frame count, dimensions, and original file size automatically and displays them so you know what you are starting with.
Adjust Settings
Set quality level (controls per-frame compression), colour count (reduce palette from default 256 to as low as 16-32 for size savings), and output dimensions (scale down to further reduce size). Preview updates live.
Compress & Download
Click "Compress" — the tool processes each frame with optimized colour quantization. The result is delivered as optimised GIF, animated WebP, or PNG (first frame only). Download with one click.
Features
Quality Control
Adjust compression quality to balance file size and visual quality. Default is balanced; reduce for smaller files, increase for higher fidelity. Effect is most pronounced on photographic content.
Color Reduction
Reduce the colour palette from GIF's maximum of 256 to as low as 16-32 colours. Most animated content looks fine at 64-128 colours; pure-line-art animations work at 16-32. Each colour-count halving roughly cuts file size in half.
Dimension Scaling
Scale down GIF dimensions to further reduce file size. A 1080×1080 GIF scaled to 600×600 typically halves the file size or better. Useful when the GIF is going to be displayed at smaller dimensions anyway.
WebP Output Option
Convert the GIF to animated WebP for dramatically smaller files (typically 70-80% smaller than equivalent GIF at the same quality). All modern browsers support animated WebP since 2020.
Size Comparison
See original and compressed file sizes with exact reduction percentage. Useful when targeting specific upload caps (under 8 MB for Discord, under 5 MB for Twitter, under 25 MB for Gmail attachments).
Browser-Based & Private
All compression happens in your browser. Your GIFs are never uploaded to any server, never logged, and discarded the moment you close the tab.
