GIF Compressor

A GIF that is too big for Discord’s 8 MB or a page-speed budget can usually lose 50–80 % of its size with no visible change: fewer colors, a slightly lower frame rate and a sensible width.

Why convert GIF to GIF

GIF stores every frame as an indexed image with up to 256 colors and no real inter-frame compression, so size scales with width × height × frames × colors. Halving the width quarters the size; going from 20 to 12 fps cuts it by 40 %; 128 colors instead of 256 saves 10–20 % on photos and much more on flat graphics.

The compressor decodes every frame (respecting the GIF’s disposal rules), drops frames to hit the target frame rate while keeping the animation’s timing, scales, and re-quantises each frame to an optimized palette — all in your browser. If nothing helps, you get the original back.

How to convert GIF to GIF

  1. Drop one or more GIFs onto the page.
  2. Choose a maximum width, a frame rate and the number of colors.
  3. Click Compress and compare the size before downloading.

About the format

GIF · Graphics Interchange Format · .gif

A 1987 format limited to 256 colors per frame, still everywhere because it is the only animated image format every app can play.

  • GIF transparency is all-or-nothing: a pixel is either fully opaque or fully transparent.
  • Animated GIFs are large — a 10-second clip can be bigger than the same clip as MP4.
  • The 256-color palette causes banding in photos; PNG or WebP is better for still images.
