Convert WebP to PNG
Got a .webp file your editor, office app or upload form
will not open? Convert it to PNG here: every pixel and the transparent
background are kept, though the PNG will be larger.
Your images are never uploaded.

How to turn a WebP into a PNG
- Choose the
.webpfile your browser or app saved, or drop several at once. - The PNG is written and optimised on your device; there is no quality setting because PNG is lossless.
- Download the PNG and open it in the software that refused the WebP.
Why “Save image” gave you a WebP in the first place
Many websites send WebP to any browser that can display it, even when
the page’s address for the image ends in .jpg or
.png. Your browser shows it happily, and saves exactly
what it received. The trouble starts afterwards, when an older photo
editor, a document template or a form that only lists “JPG,
PNG” meets the file. Converting it is the reliable fix; renaming
the extension is not, because the bytes inside are still WebP.
How much bigger the PNG gets
We measured it. Our script draws three test images pixel for pixel (so the run can be repeated exactly), saves each as a lossy WebP at quality 80 the way a website would, and then converts those WebP files to PNG with the same optimiser this page runs.
| Test image | WebP | PNG | Size |
|---|---|---|---|
| Landscape photo | 90.3 KB | 922.0 KB | 10.2× larger |
| Flat logo, transparent | 8.4 KB | 56.7 KB | 6.8× larger |
| App screenshot | 42.2 KB | 275.9 KB | 6.5× larger |
The logo row is the surprising one. As an original PNG, that same logo was only 5.4 KB, yet after a trip through lossy WebP it comes back as 56.7 KB. Lossy encoding leaves faint noise around every edge, and a lossless format has to record that noise faithfully. So if you still have the original PNG somewhere, use it — converting back from a WebP never recovers the clean original.
PNG or JPG: which should you convert to?
| Your situation | Better target |
|---|---|
| Logo, sticker, icon or anything with a transparent background | PNG — JPG cannot store transparency |
| You will edit the image and save it again | PNG — no further loss each time you save |
| A photo for an email, a form with a size limit or an old app | JPG — far smaller for photos |
| You only want a smaller WebP | Stay in WebP and re-compress it |
Frequently asked questions
Are my WebP files uploaded anywhere?
No. Your browser decodes the WebP and the PNG is written and optimised inside this tab. The page, the optimiser download and the ads make ordinary network requests, but the image you convert is not sent with any of them.
Does converting to PNG improve the quality?
No. The conversion itself loses nothing — every decoded pixel lands in the PNG exactly — but it cannot bring back detail the WebP threw away when it was first saved. You get a perfect copy of the WebP as it is, in a format more software accepts.
Is the transparent background kept?
Yes. PNG supports full alpha transparency, so transparent and semi-transparent areas of the WebP stay transparent. That is the main reason to choose PNG over JPG here: JPG would fill them with a solid colour.
Why is the PNG so much bigger than the WebP?
PNG is lossless, so it must store every pixel exactly — including the faint compression noise a lossy WebP adds. In our tests the PNG came out 6.5 to 10.2 times the size of the WebP. That is the price of compatibility, not a sign something went wrong.
What happens to an animated WebP?
Only the first frame is converted. PNG as most software reads it is a still image, and this tool draws a single frame from the decoded file. If you need the animation, keep the WebP.
Can I convert several WebP files at once?
Yes. Select or drop as many files as you need; each becomes its own PNG with its own download button. Metadata such as EXIF and embedded colour profiles is not copied into the new files.
