About this tool
Images saved from websites increasingly come down as WebP, which older versions of Photoshop, Windows Photo Viewer, and many upload forms reject. Converting to PNG keeps every pixel (including transparency) and opens anywhere.
About the formats: WebP is Google's modern web image format. It supports both lossy and lossless compression plus transparency, and typically comes out 25-35% smaller than an equivalent JPG or PNG. Every current browser displays it, but some older desktop apps and upload forms still reject it. PNG (Portable Network Graphics) is a lossless image format with full transparency support. It is the standard choice for screenshots, logos, icons, and anything with sharp edges or text, but it produces much larger files than JPG or WebP for photographs.
Everything happens inside your browser. Your file is never uploaded to a server: the conversion runs on your own device using WebAssembly, and the result is downloaded straight from memory. Close the tab and nothing is left behind.
How to use it
- Drop your WEBP files into the box above, or click to browse. Nothing is uploaded.
- Click Convert to PNG and wait a moment.
- Download the results individually or all at once as a ZIP.
Frequently asked questions
Is transparency preserved?
Yes. PNG supports the same alpha transparency as WebP.
Can I convert an animated WebP?
Only the first frame is converted to a still PNG.
Is this really free?
Yes. The site is supported by ads, and there are no limits on how many files you convert.
Are my files uploaded anywhere?
No. The converter runs entirely in your browser. Files stay on your device, which also makes it faster than upload-based converters for anything larger than a few megabytes.
Is there a file size limit?
The only limit is your device's memory. Images and audio of any normal size are fine; for video, files under about 500 MB work well on most laptops and phones.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. Very old browsers without WebAssembly support will not work.
