How to convert WebP to PNG
- Drop a
.webpfile into the box above, choose one, or paste an image. - PNG is already selected. It's lossless, so there's no quality to set.
- Select Download to save the PNG, transparency and all.
WebP vs PNG
| WebP | PNG | |
|---|---|---|
| Made for | Fast-loading websites | Editing, graphics and exact copies |
| Transparency | Yes | Yes |
| File size | Small | Larger |
| Works in | Modern browsers and most web platforms | Practically every app ever made |
How it works
The browser decodes the WebP, whether it was saved lossy or lossless, and the pixels go into a PNG unchanged. OxiPNG then compresses the file at level 2, a lossless step, and with alpha optimisation, which may change the hidden colour values of fully transparent pixels: nothing you can see changes. If the WebP was lossy, its compression marks are copied faithfully into the PNG, which won't remove them. Only the first frame of an animated WebP is converted.
Common uses
- Sticker or cut-out for slides. Stickers, emoji-style graphics and product cut-outs on websites are often WebP with a transparent background. As PNG, they drop into slide decks, documents and design tools with the background still see-through.
- A design tool won't accept WebP. Some design, print and presentation apps only import PNG or JPG. Convert to PNG so icons, logos and diagrams keep sharp edges.
- Editing a graphic many times. Each save of a lossy image loses a little more detail. Convert the WebP to PNG once, then edit and re-save it as often as you need.
