WebP to PNG
To turn a WebP into a PNG, drag the file, tap Shift and drop it on PNG. Transparent areas stay transparent, which makes PNG the right choice for logos, icons and cut-out images.
How to convert WebP to PNG
- 1
Start dragging the WebP file, from the desktop or any folder.
- 2
While you're still holding it, tap Shift. A ring of planets opens around the file, one for each format it can become.
- 3
Drop the file on the PNG planet. The PNG copy appears next to the original a moment later.

When PNG is the better target
Logos, stickers and product shots saved from the web are often WebP files with a transparent background. PNG keeps that transparency and is accepted by every design tool and document editor.
For ordinary photos without transparency, JPG gives you a much smaller file.
PlanetOS does all of this on your computer. Your files are never uploaded, and it works without an internet connection.
Questions
Is WebP to PNG lossless?
The PNG keeps exactly what's in the WebP. If the WebP was lossy, those losses were already there.
Can I do this without installing anything?
PlanetOS is an app you install once. After that it works offline and never uploads your files, unlike online converters.
