Will compression noticeably reduce quality?

At moderate settings, compression removes data that's hard to notice visually while cutting file size significantly. Lower the quality slider further only if you need maximum savings.

Is there a file size limit?

Very large files may take longer to process since compression runs in your browser, but typical photo sizes work smoothly.

Does it work for PNG files too?

This tool focuses on JPG and WebP, the formats where lossy compression gives the biggest size savings. Use the Image Format Converter first if you need to switch formats.
