When you need PNG instead of WebP
WebP is a good format for browsers, but it is not accepted everywhere. Many editors, design tools, presentation programs and upload forms ask for PNG or JPG. PNG has the added benefit of keeping transparency, so it is the right target for logos, icons, stickers and cut-outs that you saved as WebP.
If the picture is a photo with no transparency and you just need it to open anywhere, WebP to JPG gives a smaller file.
What to expect
- Bigger files. PNG stores every pixel exactly, while lossy WebP discards detail to stay small. A photo can grow many times over. A WebP that was made lossless grows less.
- No quality gain. The PNG is a faithful copy of what the WebP shows. Compression artefacts already in the WebP stay, now stored without loss.
- Transparency kept, including soft semi-transparent edges.
- Animation lost. An animated WebP gives its first frame only.
- Colours are converted to sRGB, and metadata is removed unless you choose Keep.
Speed and big files
The optimiser that makes PNG files smaller is thorough, so it takes longer than the plain conversion, especially for large pictures. It is skipped automatically above 16 megapixels. Switch Make PNG files smaller off if you want the fastest result and do not mind a bigger file. The full image converter lets you pick JPG or AVIF as the target too.
