WebP to PNG
Convert WebP images to PNG right in your browser. WebP is what modern sites serve to save bandwidth, and it's still the format plenty of desktop and print software refuses to open. PNG is lossless and keeps transparency, ideal for graphics and screenshots.

When to use WebP to PNG
Convert when the destination will not take WebP or when the trade-offs of PNG suit you better. A WebP may have been saved either lossily or losslessly depending on the tool that made it, and it can carry an alpha channel. PNG is lossless and keeps transparency, which makes it the right choice for screenshots, logos and line art. Files are larger than JPG for the same picture. PNG is lossless, so it will not add any further compression - but it cannot undo what the source already lost either, and the file will usually come out larger than what you put in. What you gain here is reach rather than quality: WebP is universal in current browsers but still unreadable to plenty of desktop and print software.

Troubleshooting
The background looks white rather than transparent
PNG does keep the alpha channel, so check the viewer first - plenty of them paint transparency white. Open the PNG over a coloured background to confirm, or the WebP may not have had an alpha channel to begin with.
The PNG is no sharper than the WebP
Expected. PNG is lossless, so it preserves exactly what it is handed - it cannot restore detail the WebP discarded earlier. Converting is worth it for editing headroom or for software that will not read WebP, not for image quality.
The output is larger than the original
PNG is lossless, so it is often larger than a lossy source. That is the trade for keeping every pixel exactly.
The upload is rejected before anything happens
The file is over the 20 MB cap. Compress it first, or split a long PDF into smaller files and process them separately.

Frequently asked questions
PNG is lossless, so this step adds no further loss. It cannot recover detail the WebP had already discarded, though, and the output is usually larger than the file you started with - that is the trade for keeping every remaining pixel exactly.
