About WebP to PNG

Choose PNG over JPG when converting a WebP for exactly one reason: the image has a transparent background and you need to keep it. JPEG has no alpha channel at all, so converting a cut-out logo or an icon that route silently paints white behind it, and there is no undoing that afterwards. PNG stores alpha properly, so the transparency arrives intact in whatever editor or document tool refused to open the WebP in the first place. The trade you accept is size. PNG compresses losslessly, and it will faithfully preserve every artifact the lossy WebP encoder left behind, often producing a file several times larger than the source. That is expected, and it is worth understanding before you are surprised by a 4MB output from a 300KB input.

Shape and export choices

The WebP is decoded in the browser, alpha channel included. Both lossy and lossless WebP decode through the same path, so it does not matter which mode the file was written in.
A canvas with an alpha-enabled context is created at the source dimensions. Critically, no background colour is painted first - that omission is the entire difference between this tool and the WebP to JPG converter.
The bitmap is drawn and encoded as PNG. PNG encoding is lossless, so the WebP's decoded pixels are reproduced exactly as they were handed over, artifacts and all.
The output size is measured and displayed alongside the original. Expect it to be larger, frequently by a factor of three to ten on photographic material.
The result is a standard 8-bit-per-channel RGBA PNG that any image editor, office suite, or operating system preview will open without complaint.

Good fits for WebP to PNG

Logo downloaded from a brand asset page

Brand kits increasingly ship WebP. Converting to PNG keeps the transparent background so the mark can sit on a coloured slide or letterhead without a white rectangle around it.

WebP rejected by a design tool

Some older versions of desktop editors and office software will not import WebP at all. PNG is the safest interchange target when transparency matters; use JPG when it does not and file size does.

Check the image before download

The PNG will almost always be bigger than the WebP, sometimes dramatically. You are storing a lossy image in a lossless container; nothing about the conversion recovers quality, it only stops discarding more.
Existing WebP compression artifacts become permanent. If the source was compressed hard, the blocking and ringing around edges are now baked into a lossless file and will survive every future edit.
Animated WebP produces a single still frame. The browser hands over the first frame only, and there is no facility here for exporting the sequence or building an APNG.
If the image has no transparency, PNG is usually the wrong destination. Converting to JPG will give you a far smaller file with no practical downside for a photograph.
Metadata in the WebP container, including any colour profile, is not written into the PNG. Verify colour-critical work before sending it to print.

Questions about WebP to PNG

Why is my PNG larger than the WebP?

PNG is lossless, so it stores every pixel exactly rather than approximating them. The WebP was smaller because it was allowed to throw information away. Growth here is normal, not a fault.

Does this improve the image quality?

No. Converting to a lossless format preserves what is there; it cannot reconstruct detail the WebP encoder already discarded.

Will the transparent background be kept?

Yes. That is the main reason to pick this over the JPG converter, which has to composite transparency onto a solid colour.

What about an animated WebP?

You get the first frame as a still PNG. Animation is not carried over, and the individual frames are not extracted.

Is the file uploaded to convert it?

No. Decoding and PNG encoding both run in the browser, and the download comes from an object URL created on the page itself.
