Tips for Best Results
For JPEG files, a quality of 75-85% usually gives a good balance between visual quality and file size. For PNG, quality doesn't apply in the same way because it is lossless. For WebP, 75-80% is often a sensible starting point. If you need to preserve every detail, use PNG format. Always test converted files before publishing to ensure quality and compatibility meet your needs.
