The conversion that keeps your transparent background
This is the right tool when the WebP has a transparent background — a logo, an icon, a cutout, a sticker. Both WebP and PNG carry a full 8-bit alpha channel, so the conversion is a clean mapping: every pixel, including its transparency value, is preserved exactly.
If you convert that same file to JPEG instead, the transparent pixels get flattened to white, and there is no way to recover them afterwards. This is the single most common mistake people make when converting graphics, and it is not reversible.
Lossless in, lossless out — with a caveat
PNG is always lossless. WebP is not always: it has both a lossy and a lossless mode, and most WebP images on the web are lossy. Converting a lossy WebP to PNG does not restore detail that was already discarded — it just stops any further loss from happening. What you get is a pixel-exact copy of the WebP as decoded.
Expect the PNG to be considerably larger, often 3–8× the WebP, especially for photographic content. For flat graphics, logos and screenshots the gap is much narrower because that is exactly the kind of content PNG's compression was designed for.
Common questions
Do my files get uploaded to a server?
No. Every tool on this site runs entirely in your browser using the Canvas and WebAssembly APIs. There is no upload endpoint in the page — you can confirm this yourself by opening your browser's Network tab while you convert a file. Nothing leaves the tab, which also means the tools keep working if you go offline after the page loads.
Does this keep the transparent background?
Yes. Both formats support an alpha channel and it is copied through unchanged.
Will converting improve the image quality?
No. If the WebP was lossy, that detail is already gone. PNG preserves what remains without adding further loss, which is useful before editing, but it cannot reconstruct anything.
Which should I use for a website, PNG or WebP?
WebP, in almost every case — it is smaller and supported by every current browser. Convert to PNG when a specific tool or workflow requires it, not for publishing on the web.
