How this WebP converter works
Drop a .webp file and you get a .png back. Your browser decodes WebP every day to render web pages, so the work is already possible on your machine: the image is drawn onto a canvas and re-encoded as PNG right there. Nothing travels to a server. Drop twenty files and twenty PNGs appear below, with a zip button for the whole batch.
When you reach for this
- An app rejects the file. Photoshop CS6, Office 2016, a lot of print shops and plenty of upload forms still refuse .webp.
- You saved a picture from a website and it arrived as .webp because that is what the site served you.
- A transparent background has to survive. WebP and PNG both store an alpha channel, so a cut-out logo stays cut out.
- You want a format you can edit from. PNG is lossless, so saving again in an editor costs you nothing.
What changes when you convert
Your PNG will be bigger, sometimes several times bigger. WebP compresses aggressively; PNG records every pixel exactly. That size is what you pay for a file everything opens.
Detail does not come back. If the original WebP was saved with lossy compression, the discarded detail left the file for good, and no converter reconstructs it. You get a faithful PNG copy of the WebP you have.
An animated WebP converts to one still image, its first frame, because a PNG holds a single picture.
Frequently asked questions
Does my image get uploaded anywhere?
No. The decode and the encode both run in the page you are looking at. Turn off your wifi after the page loads and the converter still works.
Why is the PNG so much larger?
WebP throws away information you are unlikely to notice and packs the rest tightly. PNG keeps every pixel and compresses without discarding anything. Photographs show the biggest jump; flat graphics and screenshots stay close to their original size.
Can I convert a folder of files at once?
Drop as many as you want. Each one gets its own download button, and the last button packs them all into a zip.
My WebP is animated. What do I get?
The first frame, as a single PNG. Animation needs a format built for frames, such as GIF or APNG.
The colors shifted a little. What happened?
Your browser converts the image to sRGB while decoding it, and the output PNG carries no embedded color profile. Pictures tagged with a wide-gamut profile such as Display P3 can look slightly different after that step. Ordinary sRGB images come through unchanged.
Is there a file size limit?
Everything runs in memory, so very large images are limited by your device rather than by us. Phones start struggling around the 50 MB mark.
