Optimize GIF for Web

One click to cap the width, trim excess frames and lower quality — free, entirely on your device.

What "optimize" changes

This tool bundles the two biggest levers for GIF file size into one step: it caps the width (scaling proportionally down if your GIF is wider) and applies a balanced compression pass, aiming for a file that loads quickly on a web page or sends cleanly through chat apps without a visible drop in quality.

GIFs already narrower than your chosen max width are compressed only — nothing is upscaled.

Why width matters more than you'd expect

GIF file size scales roughly with the number of pixels per frame multiplied by the number of frames — so cutting the width in half doesn't just save half the space, it can cut the file to a quarter of its original size, since both dimensions shrink together. That's why a modest width reduction, from say 800px down to 480px, is usually the single biggest lever available before you even touch quality settings.

400-480px is a good general-purpose target for GIFs shared in chat apps, embedded in emails, or dropped into a ticket or comment thread — large enough to read clearly, small enough to load instantly. If your GIF is destined for a full-width website hero, push the max width slider up to 640-800px instead.

What happens behind the one-click button

Under the hood, this tool runs the same two operations you'd otherwise do manually with the separate Resize GIF and Compress GIF tools — it decodes every frame, scales the whole set down if it's wider than your chosen cap, rebuilds the color palette at a balanced quality level, and re-encodes everything into one output file. Bundling both steps together saves a round trip through two separate tools when your goal is simply "make this smaller."

Every part of that process runs locally in your browser tab through a WebAssembly-based GIF engine — no upload occurs at any point, and the file never touches a server.
