Will optimizing my GIF change how it looks?

Lossy mode may reduce the number of colors slightly, which can cause minor visual differences. Lossless mode keeps every pixel exactly the same while still removing redundant data across frames.

How much smaller can a GIF get?

Animated GIFs often contain large amounts of redundant pixel data between frames. Optimizing can reduce file size by 30–70% depending on the content, especially when cropping transparent edges and compressing the color palette.

Does this work with static GIFs too?

Yes. Static GIFs are optimized the same way — color palettes are compressed and transparent regions are cropped if enabled.

Shrink an animated GIF online

Animated GIFs are notoriously large and uncompressed on the web, often weighing tens of megabytes. This page shrinks a GIF by compressing color palettes, removing redundant pixels across animation frames, and cropping transparent regions — all without changing the playback speed or dimensions.

How to shrink a GIF

Upload a GIF up to 40 MB.
Choose the optimization effort and compression mode.
Press Convert file and download the smaller GIF.

Fast uses the quickest optimization pass. Smallest spends more time for a tighter file. Lossless keeps every pixel intact while still removing redundant frame data.

What you get

You get another GIF. Same dimensions. Same frame count and playback speed. Usually a significantly smaller number of bytes, which is what you want before you upload it somewhere with a size cap or share it in a chat app.

It will not convert your GIF to video. If you need a video format, use a dedicated transcoder instead.
