Why convert PNG to WebP?
PNG stores images losslessly, so every pixel is kept exactly. It supports full transparency, which makes it the standard for logos, icons and screenshots. Photos saved as PNG are much larger than JPG.
WebP files are usually 25–35% smaller than JPG at the same visual quality. Converting images to WebP makes websites and online stores load faster, which also helps search rankings.

- Use the quality slider to balance size and quality. 80–90% is visually lossless for most photos.
