Overview
CheetahO is an image optimization API that compresses and resizes photos without visible quality loss. By reducing file sizes before serving them, your web pages load faster and use less bandwidth. It supports JPEG, PNG, GIF, and WebP formats and can convert between them.
Beginner Tip
Always request lossy compression first—it typically reduces file size by 60–80% with no visible difference. Only switch to lossless if transparency or pixel-perfect accuracy is required.
