Compression can optimize image encoding, remove redundant data or trade some detail for fewer bytes. The result depends on the image and format, so compare visual quality as well as file size.
Common image formats, not a verified support list. Check current input and output formats in the tool.
This introduction page does not accept or process images. Local-only processing has not been verified for the independent tool, so review its data handling notice before selecting files.

The independent tool’s current format support has not been verified. JPG, PNG and WebP are common image formats, but check the tool’s input and export options before selecting a file.
Lossy compression discards some detail; lossless compression preserves pixel information. Compare text, edges and gradients at the size you plan to display the image.
There is no fixed reduction percentage. Results depend on image content, dimensions, format and quality settings; an already optimized image can even become larger when re-encoded.
WebP images can be re-encoded, but a smaller result is not guaranteed. Check whether the independent tool currently accepts WebP and which output formats it offers.
