How does image compression work?

Image compression reduces file size by optimizing image data. Depending on the format, it may remove unnecessary metadata and apply efficient encoding to keep visual quality high while making the file smaller.

Which image formats are supported?

This tool supports JPG (JPEG), PNG and WEBP images.

Will compression reduce image quality?

Compression can slightly reduce quality at lower settings. Using a balanced quality level (for example 75–85) usually keeps images looking the same while significantly reducing file size.
