Accepts WebP. No size limit, no sign-up.
Choose this over WebP to JPG when the image has a transparent background. PNG is the universally supported format that carries an alpha channel, which JPG cannot.
The specific problem this solves
You saved a logo or a cut-out product image from a website and got a .webp. The software you need to use it in — an older design tool, an office suite, a print upload form — rejects the extension. Converting to JPG would work for compatibility, but it would fill the transparent background with solid colour and ruin the asset.
PNG is the answer: it is understood by essentially everything, and it keeps the alpha channel exactly as it was.
Expect the file to grow
WebP is a modern compressed format and PNG is lossless, so the PNG will usually be larger — often several times larger on photographic content. That is the price of universal compatibility and pixel-exact storage.
For flat-colour graphics the gap is much smaller, and an optimised PNG can occasionally come out competitive. It depends entirely on how much fine detail the image contains.
We optimise the PNG before you get it
A PNG written straight from decoded pixels is usually far bigger than it needs to be. Breezo runs every PNG through oxipng, a lossless optimiser compiled to WebAssembly, which selects better row filters and drops redundant metadata.
This changes no pixels — the output is bit-identical in image content — but on our flat-colour test image it took a naive 410 KB encode down to 47 KB. Most converters skip this step entirely and hand you the larger file.
Local processing, verifiable
Your browser already contains a WebP decoder, so no download is needed to read the file. The PNG encoder and optimiser are WebAssembly modules fetched only when you actually convert something.
No part of this touches a server. Open DevTools while converting and check for yourself.
Frequently asked questions
Is the transparency preserved?
Yes. PNG has a full alpha channel, so a transparent background in the WebP survives intact. This is the main reason to choose PNG over JPG here.
Why is the PNG bigger than the WebP?
WebP uses modern lossy compression; PNG stores every pixel losslessly. On photographs the increase can be several-fold. That is expected, not a fault.
Does this restore quality lost by WebP compression?
No. Detail discarded when the WebP was created is gone. PNG preserves what remains exactly but cannot reconstruct anything.
What about animated WebP?
The first frame is converted. PNG cannot hold animation — APNG exists but is not what standard PNG tools expect.
Is anything sent to a server?
No. Decoding, encoding and optimisation all run in your browser tab.
