Why convert WebP to PNG
This is the conversion to choose when a WebP has a transparent background and you need it to stay transparent — a logo, an icon, a cut-out product shot. Converting that same file to JPG would fill the transparency with white and ruin it. PNG is also the safer choice when the image is about to be edited, since it is lossless and repeated saves will not degrade it.
What this conversion costs you
- The file grows substantially. WebP is a much more efficient format. Expect the PNG to be several times larger for the same picture.
- Nothing visible. Because PNG is lossless, the decoded WebP is stored exactly. No further quality is lost in this direction — the cost is entirely in bytes.
When not to do this
If the image has no transparency and is a photograph, convert to JPG instead. You will get a far smaller file and no meaningful visual difference.
Common questions
Does WebP to PNG keep transparency?
Yes. Both formats support an alpha channel, so transparent areas stay transparent. This is the main reason to choose PNG over JPG here.
Does this conversion lose quality?
No further quality is lost. PNG stores the decoded image exactly as it was. Any compression WebP already applied remains, but nothing new is discarded.
Why is the PNG so much larger than the WebP?
WebP compresses far more efficiently than PNG. A file several times larger is the normal and expected result.
