Convert WebP to PNG
Turn a WebP into a PNG that keeps its transparent background, for editors, slides and apps that will not open WebP. In your browser, no upload.
How to convert WebP to PNG
- Drop a WebP on the box above, or up to 20 at once. The file picker on this page shows WebP files.
- Convert to already shows PNG at 100%, which keeps every pixel and every see-through edge.
- Press Convert image and compare the sizes. A photo gets much larger as a PNG.
- Download the PNG, or all of them together in one ZIP.
When I pick PNG for a WebP
PNG makes sense for a WebP in two cases. The first is transparency: a logo, an icon or a cut-out product picture saved from a website that has to sit on a coloured slide or in a design. A JPG would put it in a white box. The second is editing: a PNG loses nothing when you save it again and again, so it makes a good working copy.
For a plain photo neither applies, and my numbers show why. I made WebP copies of three of my published photos with the settings my site uses for the WebP files it serves, plus my transparent test logo, and converted all four to PNG on this page in Chromium.
What PNG does to the file size
| Image | WebP | PNG at 100% |
|---|---|---|
| Lake Jasna, June 2019 | 960 × 1200 px, 152.8 KB | 1.3 MB, 752.8% larger |
| Clay figure, Metelkova, March 2023 | 1200 × 800 px, 102.7 KB | 1.0 MB, 924.7% larger |
| Red bicycle, Metelkova, March 2023 | 1200 × 800 px, 248.4 KB | 1.8 MB, 649.1% larger |
| Logo with transparency | 640 × 320 px, 10.1 KB | 40.6 KB, 301.5% larger |
The photos became seven and a half to ten times heavier, for no visible gain. The logo grew about four times, to 40.6 KB, and kept its transparency: the corners stayed fully see-through and the half-transparent orange shape stayed half-transparent.
Transparency comes along
A PNG stores see-through areas just as a WebP does, including the soft, partly transparent edges around a shape. The difference from WebP to JPG is plain with my logo: there it landed on solid white, here it can go on any background you like.
Does WebP to PNG lose quality?
The step itself loses nothing. At 100% the PNG holds exactly the pixels the browser decoded from the WebP. It cannot bring back what the WebP gave up when it was made, though, so a PNG of a small, soft WebP from a website is still a small, soft picture, only heavier.
Below 100% the slider tries fewer colours and keeps them only when the picture looks the same. That suits graphics: my logo at 90% came out at 19.2 KB instead of 40.6 KB. For the lake and the clay figure at 90% it changed nothing, and I got the full PNG again.
Tips for converting WebP to PNG
- Use PNG for logos, icons and cut-outs. For photos, WebP to JPG gives a far smaller file.
- Save the largest version a website offers; converting does not add pixels.
- Try 90% for a logo or icon. It often halves the PNG without a visible change.
- If a program refuses the PNG as too big, make the picture smaller with the Image Resizer rather than lowering the quality.
- Keep the PNG as your working copy while you edit, and make the final JPG or WebP from it once.
Privacy
Your image never leaves your device. Conversion happens entirely in your browser, so nothing is uploaded or stored, and you do not need an account. Support for HEIC files is included on this site and also runs in your browser.
Frequently asked questions
Is converting WebP to PNG lossless?
Yes, at 100%, where this page starts. Every pixel of the WebP, transparent ones included, goes into the PNG unchanged. The detail the WebP dropped when it was created stays lost, so the PNG looks exactly like the WebP.
Does the PNG keep the transparent background?
Yes. PNG stores transparency just like WebP, so see-through areas and soft edges stay as they were. My test logo kept every clear corner as a 40.6 KB PNG; as a JPG the same logo sat on white.
Is WebP better than PNG?
On a website, usually: my logo was 10.1 KB as WebP and 40.6 KB as PNG. PNG wins where the file has to open everywhere or be edited many times, since older programs read PNG and it never loses detail when saved.
What is the difference between WebP and PNG?
PNG is always lossless and opens in nearly every program. WebP can be lossless or lossy, which makes photos far smaller, and keeps transparency either way. Browsers show both; many older editors and apps open only the PNG.
How do I change a WebP to PNG on my phone?
Open this page in the phone's browser, tap the box above and pick the WebP from your files or downloads. The conversion runs on the phone itself, and the PNG is saved where your browser keeps its downloads.
