When WEBP to PNG turns WEBP into PNG
Use PNG when you need the WEBP image with transparency intact and a format older tools accept.
What WEBP to PNG changes in the picture
The image is re-saved as PNG, which can keep a transparent background.
The PNG is often larger. That is normal.
When WEBP to PNG is the right page
WEBP to PNG sits on this site because WEBP and PNG are not interchangeable, even when they look similar in a file list. Use PNG when you need the WEBP image with transparency intact and a format older tools accept. Current browsers display WEBP. Older desktop apps, some CMS fields, and many printers still do not. Use PNG when a logo must stay crisp or when the background must stay transparent.

What you give up by leaving WEBP
WEBP is what many websites prefer in 2026 because the file is smaller than JPG at a similar look. Word and print shops often reject it, so it is the wrong file for those handoffs.
Keep a JPG or PNG master if the image must leave the website.
What you gain, and do not gain, with PNG
The download has to be PNG, because that is the format the next step named. Use PNG when a logo must stay crisp or when the background must stay transparent. Text in a screenshot stays sharper than it does in a heavy JPG.
PNG does not rescue a photo that was already compressed as JPG.
A test that matches the real file
Start from the question the other software asked. If it asked for PNG, WEBP to PNG is the matching page. If it asked for something else, switch tools instead of hoping a similar extension will pass. Use PNG when you need the WEBP image with transparency intact and a format older tools accept. The image is re-saved as PNG, which can keep a transparent background. The limit is the part people skip, and it is the part that decides whether the download is usable. The PNG is often larger. That is normal. The file stays in your browser and is not uploaded. The limit is 100 MB. Keep the original until the download has been opened in the program that will use it. Check three things in the download: it opens, the WEBP material you cared about is still there, and the file size or the layout is what the form described. A new extension alone is not those three things. If a portal, a teacher, or a client rejects the file, send them the original WEBP as well when you are allowed to. WEBP to PNG is a convenience copy. It is not a new master. Photos fail uploads for three separate reasons: the format name, the pixel size, and the kilobyte size. WEBP to PNG only does the WEBP to PNG step. If the form also prints a pixel size or a 20 KB or 50 KB cap, do that step with the matching tool, starting from the original each time. A second lossy save will not recover detail.
Here is the decision for WEBP to PNG. You start with WEBP and you stop when a real program accepts PNG. It is a sensible web copy of a photo or a transparent graphic. Photographs are usually much larger as PNG than as JPG, with little visual gain. If those two sentences describe a tradeoff you do not want, do not convert. Renaming the extension by hand will not do this job. Running the tool twice on its own output will not do it either.

A related step, if you still need one, is PNG to WEBP.
Other jobs start from the homepage, where each tool is named for the conversion it actually does.
