Drop WebP files above, download PNGs. Conversion is lossless, PNG throws nothing away, and transparency survives intact.
Where WebP comes from: most images saved from websites arrive as WebP, because sites serve it for speed. Browsers open it; plenty of software doesn't. Older editors, office tools, upload forms, print workflows. PNG is the universally accepted lossless format, which makes this the standard fix for "saved an image, nothing will open it."
What converts cleanly:
- Transparency: both formats support full alpha; transparent stays transparent.
- Quality: writing the PNG is lossless. If the website compressed the original, that already happened upstream.
- Animated WebP: PNG is a still format, and what comes back is the first frame.
Size expectation: PNGs run larger than the WebP they came from. For photos it is often several times larger, which is normal and is simply what lossless storage costs. If the goal is a smaller shareable photo, WebP to JPG (linked below) is the better tool.
If the WebP was saved lossily, the PNG keeps those compression marks exactly as it finds them, because lossless storage preserves whatever it is given, flaws included.
Drop one file or fifty, with per-file progress and sizes and a ZIP at the end.
