When to choose PNG over JPG
- Transparent backgrounds: logos, stickers, product cut-outs.
- Screenshots, diagrams and images with text, where JPG would blur the edges.
- Images you plan to keep editing. PNG doesn’t add new compression artefacts each time you save.
What to expect
PNG is lossless, so it keeps every pixel of the decoded WebP, including transparency. The price is size: a PNG is usually several times larger than the WebP it came from, especially for photos.
If the file must stay small, choose a size target. PNG has no quality setting, so the tool reduces the pixel dimensions to fit. For photos, converting to JPG instead is usually the better trade.
How the conversion works
- Your browser decodes the WebP with its built-in decoder.
- The pixels, including the alpha channel, are saved as PNG, at full size or scaled to fit your target.
- You download the PNG. EXIF and other metadata are not copied into it.
Frequently asked questions
Is my image uploaded?
No. The conversion runs in your browser’s memory and the PNG is handed to you as a download. There is no upload endpoint.
Is the transparency kept?
Yes. PNG supports full transparency, so transparent and semi-transparent areas of the WebP stay exactly as they were.
Why is the PNG so much larger than the WebP?
WebP usually uses lossy compression, while PNG stores every pixel exactly. Lossless storage of a detailed image takes far more bytes. That is expected, not an error.
Can I make the PNG smaller?
Choose a size target and the tool will reduce the pixel dimensions until the PNG fits. If you don’t need transparency, the WebP to JPG converter produces much smaller files.
