Why use PixelTools to compress gif
Full animation preserved
Every frame of your animated GIF is decoded and re-encoded, so your animation stays intact. No frames dropped, no timing lost.
Palette-based compression
GIF uses an indexed color palette (up to 256 colors). The quality slider adjusts how many colors are retained — lower means smaller files with slightly less color fidelity.
Batch compress GIFs
Drop as many GIF files as you need and compress them all at once. Download individually or as a single ZIP archive.
100% private — no upload
All compression happens in your browser using WebAssembly and the Canvas API. Your GIFs never leave your device.
Three steps to a smaller GIF
- 1
Upload your GIF
Drag and drop one or more GIF files onto the page, or click to browse. Animated GIFs are fully supported — every frame is preserved.
- 2
Adjust quality
Use the quality slider to control how many colors are kept in each frame's palette. The default 80% removes redundant colors invisibly. Go lower for maximum size reduction.

Download your compressed GIF
Compression happens instantly in your browser. Download files individually or all at once as a ZIP. Nothing is uploaded — your GIFs stay on your device.
Built for anyone who shares GIFs
Whether you're shrinking a reaction GIF for Slack, optimizing an animated hero for your landing page, or compressing a product demo for a README — PixelTools handles it instantly in your browser.
Social media & messaging
Most platforms cap GIF uploads at a few MB. Compress your animated GIFs to hit size limits without re-recording or re-exporting from scratch.
Email & newsletters
Animated GIFs in emails can slow load times significantly. Compressing them keeps your campaigns light and ensures they display quickly in every inbox.
Web & landing pages
Heavy GIFs are one of the biggest page weight culprits. Compress them to improve Core Web Vitals scores and reduce bounce rate.
Slack & team tools
Slack has a 100 MB file limit but animated GIFs over a few MB are slow to load. Keep your reaction GIFs snappy by compressing them before uploading.
Presentations & docs
Keynote, PowerPoint, and Google Slides all embed GIFs directly. Smaller files mean faster load times and smaller presentation exports.
App UI & product demos
Product walkthroughs and UI demos often ship as GIFs in READMEs or docs. Compress them to keep your repository light without losing animation quality.
Frequently asked questions
Does compressing a GIF remove frames?
+
No. PixelTools decodes every frame in your animated GIF and re-encodes them all. The animation loop, timing, and frame count are fully preserved.
How does GIF compression work?
+
GIF files use a color palette of up to 256 colors per frame. Compression works by reducing the number of colors in that palette. Fewer colors = smaller file. The quality slider controls how aggressively colors are reduced — lower quality means fewer colors and a smaller file.
Will the quality slider affect animation smoothness?
+
No. The quality slider only affects color fidelity — how many colors are used in the palette. Lower values can cause banding in images with gradients, but the animation timing and frame rate are unaffected.
Is PixelTools GIF compressor free?
+
Yes, completely free with no limits. Compress as many GIFs as you want, as often as you want. No account, no trial, no subscription.
What is the maximum GIF size I can compress?
+
PixelTools can handle GIF files up to 50 MB. Large animated GIFs with many frames may take a few seconds to process depending on your device.
Are my GIFs uploaded to a server?
+
No. All processing happens entirely in your browser. Your GIF files never leave your device — there is no server upload, no cloud processing, and no data stored anywhere.
