The WebP → PNG cycle
A surprising number of desktop editors, scientific tools and older plugins still refuse WebP on import. PNG opens everywhere and loses nothing.
Transparency survives the cycle: both stocks carry a full alpha channel. PNG is lossless, so weight follows content: graphics shrink, photos grow. Either way, re-encoding through the canvas collects EXIF like lint: camera model, GPS coordinates and timestamps are stripped from the folded copy.
Choose PNG when the image is going into an editor, a presentation or a design tool. It keeps everything the WebP contained, including transparency, in a format that every program on every platform can read.
The file will grow, sometimes by a factor of five or more for photographs. That is expected: PNG stores pixels without lossy compression. Keep the original WebP if you want the small version for publishing.

Questions at the counter
Is WebP to PNG lossless?
Yes. PNG is a lossless container, so the copy preserves the WebP exactly as decoded, with no second generation of compression, ever.
Why is the PNG so much larger?
Because it refuses to throw information away. WebP’s clever prediction and arithmetic coding collapse the same pixels far smaller. Treat the PNG as a working copy for editing, not for storage.
Does transparency survive?
Perfectly. Both formats carry full alpha channels, so every soft edge arrives exactly as it left.
Is the conversion really private?
Yes, architecturally. This page is static files; there is no server to receive an upload. Your WebP is decoded and re-encoded inside this tab by your own machine, and you can watch the absence of network traffic in your browser’s developer tools.
Before you convert
A converter can change the container. It cannot tell you whether that was the right call for this particular image. These cover the decision itself. They were written from building the encoders that run on this page, and are checkable against your own files.
