CodeKitHubWhat Is This Tool?
GIF is a 1989 format that stores every frame as a full palette-based image — which is why animated GIFs get enormous. Compressing one means attacking the three things that determine its size: color count per frame (GIF allows max 256), pixel dimensions, and the number of frames.
This tool decodes each frame, optionally scales it down, re-quantizes its palette to your chosen color budget, and can drop every second frame while keeping the timing (the animation plays at the same speed, slightly less smoothly). Everything runs locally — decoding uses your browser's built-in engine, encoding an open-source GIF encoder.
Why Use It?
- Three real levers — colors, scale, frame-drop — each with clear trade-offs, combined savings often 60–80%.
- Timing preserved when dropping frames: the GIF plays at the same speed.
- Local processing: GIFs (often memes or screen recordings with private content) are never uploaded.
- Batch support, per-file savings shown, free, no watermark.
- Honest fallback: tells you if your browser can't decode GIF frames instead of failing silently.
How to Use
- Drop GIF files onto the box (the encoder loads automatically, once).
- Set colors — 128 is usually invisible; 64 for bigger savings.
- Optionally scale to 75%/50% — the single biggest lever for large GIFs.
- Tick frame-drop for long recordings where slight choppiness is fine.
- Download each compressed GIF; savings are shown per file.
Example
Input
screen-recording.gif — 8.4 MB, 480 framesOutput
screen-recording-compressed.gif — 2.1 MB (−75%), 50% scale + 128 colorsScale is the strongest lever: half the dimensions is a quarter of the pixels per frame.
Frequently Asked Questions
Which setting saves the most?
Scale, by far — 50% scale cuts pixels by 75% across every frame. Then frame-drop (roughly halves size), then colors. For a huge GIF, combine all three.
Will dropping frames change the animation speed?
No — the remaining frames' delays are doubled so the total duration is identical. Motion just gets slightly less smooth, which for screen recordings is usually unnoticeable.
Why does my browser say it can't decode the GIF?
Frame-by-frame decoding uses the ImageDecoder API, available in Chrome, Edge and recent Firefox. Older browsers and some Safari versions lack it — the tool tells you honestly rather than producing a broken file.
Should I even be using GIF in 2026?
Honestly: often not. An MP4 or WebM of the same clip is 5–10× smaller at better quality, and every platform plays them. GIF still wins where autoplay-without-controls matters (README files, some chat apps). If GIF is required, this tool makes it bearable.
Is my GIF uploaded during compression?
No — decoding and re-encoding run entirely in your browser. Screen recordings with sensitive content stay on your machine.
