Convert WebP to PNG
Converting WebP to PNG takes two actions here: drop the .webp file in the box and click Convert to PNG. It executes locally through WebAssembly in your browser, with no upload, queue or signup involved.

Why convert WebP to PNG?
PNG is the safest handoff format for editing: when a designer, print shop or stock-photo pipeline cannot ingest WebP, a lossless PNG copy is the version that preserves both pixels and transparency. Unlike a detour through JPG, nothing further is sacrificed and cutout graphics keep their alpha channel. This direction also future-proofs assets pulled from the web, since a PNG will open in effectively every editor, viewer and office suite released in the last twenty-five years.
What is WebP?
WebP is an image format Google released in 2010, built on VP8 video coding. It offers both lossy and lossless modes, supports transparency in both, can hold animation, and typically lands 25-35% smaller than a comparable JPG. Every modern browser has rendered it since Safari 14 arrived in 2020, but plenty of desktop software, older CMS upload forms and printing services still refuse it.
What is PNG?
PNG (Portable Network Graphics) is a lossless image format from 1996. It compresses with DEFLATE, keeps every pixel exactly as authored, and supports a full 8-bit alpha channel for transparency. That makes it the default choice for screenshots, UI mockups, logos and anything with sharp edges or text. The tradeoff is size: photographs stored as PNG are often several times larger than a visually identical lossy file.
Quality and what to expect
The PNG is an exact lossless capture of the decoded WebP pixels. If the source WebP was lossy, its existing compression artifacts are preserved verbatim, not magnified and not repaired. Transparency, including partial alpha like soft shadows, transfers completely. Expect files to grow, sometimes a lot: PNG pays the lossless price, and a photographic WebP can balloon several-fold. Animated WebP is not supported as animation; you get a single frame at most, since PNG here is a single-image target.
WebP to PNG FAQ
Does the alpha channel survive the conversion?
Fully. Both formats support 8-bit alpha and the pipeline copies it through, so transparent backgrounds, feathered edges and semi-opaque overlays arrive intact in the PNG.
Why is the PNG so much larger than the WebP was?
WebP was likely compressing lossily and PNG must store every decoded pixel without loss. The size jump is the cost of a format that any tool can edit safely. If size matters more than lossless fidelity, JPG might be the better target.
Is this better than just renaming the file to .png?
Renaming does nothing to the bytes; software that sniffs file contents will still see WebP and may refuse it. This converter actually re-encodes the pixels into the PNG container, which is what picky applications require.
Where does the conversion run?
In a web worker on your device, using libwebp and a PNG encoder compiled to WebAssembly. Your file does not traverse the network, so there is nothing for a server to log, keep or leak.
