0 = lossless, 200 = maximum compression. 60-100 is ideal for most GIFs.
Fewer colors = smaller file. 128 works for most animations.

How to Compress GIF Files Online
GIF files can be surprisingly large. A 5-second animation can easily reach 10MB or more, making it impractical for email, messaging apps, and websites. Pixotter's GIF compressor reduces file size without destroying the animation quality you care about.
Unlike server-based tools, Pixotter processes your GIFs entirely in your browser. The file never leaves your device. This makes compression instant and completely private, with no upload wait times, no watermarks, and no file limits on the free tier beyond 10MB per file.
Three Compression Levers
Lossy compression merges pixels that are nearly identical between frames. At a setting of 80, most people cannot see the difference from the original. Color reduction limits the palette from 256 colors down to as few as 2. Reducing to 128 colors often saves 30-40% with minimal visual impact. Optimization level controls how thoroughly the encoder searches for redundancy. O3 takes slightly longer but produces the smallest files.
Common Scenarios
Sharing GIFs on Discord, Slack, or Telegram often means hitting upload limits. The Discord preset targets the 8MB cap with aggressive but visually clean settings. For web publishing, aim for under 2MB to keep pages loading fast. For email, most providers cap attachments at 25MB, but smaller GIFs load faster in the recipient's client.
Pixotter preserves transparency, frame delays, and loop counts during compression. If you need further optimization, chain the compress step with a resize step to scale down the dimensions, or convert to WebP for even smaller animated files.

Frequently Asked Questions
Is GIF compression free on Pixotter?
Yes. Compress unlimited GIF files for free with no signup. Free tier supports up to 20 GIFs per batch (10MB each). All processing happens in your browser, so your GIFs never leave your device.
How does GIF compression work?
Pixotter uses lossy compression to reduce inter-frame differences, combined with color palette reduction and frame optimization. The lossy setting controls how aggressively similar pixels are merged. Higher values mean smaller files but more visible artifacts. A value of 60-100 is ideal for most animations.
Will compressing my GIF ruin the animation?
No. The animation, frame timing, and loop behavior are all preserved. Lossy compression merges nearly identical pixels between frames, which is often invisible to the human eye. Start with the default settings and use the before/after preview to judge quality.
How do I compress a GIF for Discord?
Discord limits uploaded files to 8MB (25MB for Nitro). Click the "Discord (8MB limit)" preset, which sets lossy to 100, colors to 128, and optimization to O3. This combination typically achieves 50-70% size reduction while keeping the animation looking clean.
What is the difference between lossy level and color reduction?
Lossy compression reduces file size by merging pixels that are nearly the same color between animation frames. Color reduction limits the palette of each frame. Both reduce file size, but they work independently. Combining them produces the best results. Start with lossy compression first, then reduce colors if you need further savings.
Can I compress GIFs in batch?
Yes. Drop up to 20 GIF files at once and they will all be compressed with the same settings. Download individual results or grab everything as a ZIP file.
