WebP to PNG

Why the internet keeps handing you WebP

Websites adopted WebP aggressively because it is dramatically smaller than JPG or PNG — faster pages, lower bandwidth bills. The side effect is that saving an image from the web increasingly lands a .webp file on your desktop, and a surprising number of desktop applications, CMS editors, and office tools still refuse to open it.

PNG is the escape hatch: lossless, thirty years old, and accepted by every editor, uploader and operating system. Converting WebP to PNG is about getting your image into a format the rest of your software will actually accept.

What the conversion does to pixels

The decoder expands the WebP — VP8 lossy or VP8L lossless — into raw pixels, and the encoder writes those pixels as PNG with no additional loss. For lossless WebP sources the trip is pixel-perfect. For lossy WebP (most website photos), the conversion cannot undo compression artifacts that already exist in the file; what it guarantees is that no new damage happens from here on, since PNG never re-compresses.

Transparency carries through exactly: website logos and UI cutouts saved as WebP keep their alpha in the PNG. Animated WebP is the one structural casualty — PNG has no animation concept, so the first frame converts and the rest is dropped, which we state plainly rather than silently flattening.

The conversion itself is instant; large images may take a second or two longer purely for upload time.

A note on file size

Expect the PNG to be larger than the WebP — often several times larger. That is not a defect; it is the entire economics of the web in miniature. WebP exists to be small in transit, PNG exists to be universally readable and lossless. Use the PNG for editing and uploading to tools that demand it; keep the WebP as the compact reference if you need one.

Privacy

Images pass over HTTPS, are processed in memory, and both copies are deleted automatically within 24 hours. No account is required, and the site runs no third-party ad networks — the privacy policy is short because there is little to hide.
