About this setting
Why PNG files are so large
PNG is lossless: it stores every pixel exactly, which is ideal for logos and screenshots but wasteful for photos. A photo saved as PNG is often five to ten times the size of the same photo as a JPG. This tool makes the file smaller by saving it in a lossy format — WebP by default, because it keeps transparency.
It does not re-optimise the PNG itself. If you must keep the PNG format, for a print shop or an app icon for example, the file size stays close to the original; choose WebP wherever the place you upload to accepts it.
Tips
- Keep WebP selected for logos and cut-outs with a transparent background.
- Choose JPG for photos that were saved as PNG by mistake — transparent areas become white.
- For screenshots with small text, check the preview at a quality of 85% or more.

FAQ
Good to know
Will my transparent background survive?
Yes with WebP, which keeps transparency. JPG has none, so transparent areas turn white.Can I keep the file as a PNG and still make it smaller?
Not with this tool. It makes PNG files smaller by saving them as WebP or JPG; a PNG stays lossless, so its size depends on the image.Is WebP accepted everywhere?
Every current browser and most social networks and site builders accept WebP. Some forms and older programs still want JPG or PNG, so check before you upload.
