When should I choose a 10MB target?

Choose 10MB when your destination accepts files up to 10MB, such as images and GIFs attached to GitHub issues and comments. On Tumblr, 10MB is the upload ceiling, but GIFs over 5MB may show only the first frame, so a 5MB target is safer there. 10MB is not a universal limit; check where the GIF is going.

How many bytes is 10MB in this tool?

The tool counts 10MB as 10 × 1024 × 1024 = 10,485,760 bytes and shows the byte count under the target input. Some sites count 1MB as 1,000,000 bytes. If an upload is rejected right at the limit, enter 9.5 instead.

What can change when compressing a GIF to 10MB?

The tool can reduce colors and, when allowed, dimensions or frame count to try to reach the target. These changes can affect detail and animation smoothness. Some files cannot meet the target with the selected settings; compare the preview and size before downloading.

Is my GIF uploaded to a server?

No. Compression runs in your browser with a WebAssembly build of Gifsicle, so the file stays on your device.
