  3. Select output format (JPEG or WebP).
  4. Click Compress Image and download the optimized result.

  • Instant Preview & Download: Download the compressed file immediately.

Frequently Asked Questions

Why does the output format change from PNG to JPEG/WebP?

PNG uses lossless compression, making it mathematically impossible to reach arbitrary target file sizes without posterization. JPEG and WebP offer fine-grained lossy quality control.

Is my image sent to a server?

No. All compression is executed in your browser via the HTML Canvas and Blob APIs.
