WEBP to PNG converter: make your images open everywhere
You saved an image from the web, and now it refuses to open in your photo editor or gets rejected by an upload form—welcome to WEBP. Offcloud converts your WEBP files to universally supported PNG directly in your browser, free, with no signup. Nothing is ever uploaded, so your images never leave your device.
Why convert a WEBP image to PNG?
WEBP has become the default image format across much of the web, so images you save from a website often end up on your disk with a .webp extension. That is fine until you try to open one in an older version of Photoshop, insert it into a document, or attach it to an upload form that only accepts JPG or PNG. Plenty of software and platforms still do not recognize the format at all.
PNG solves the problem in one move. It has been a standard since the 1990s, so virtually every application, operating system, and upload form accepts it. It is a lossless format, and it fully supports transparency, which makes it the natural target when you need a WEBP image to just work: profile pictures, presentations, print orders, administrative portals, and everything in between.
How it works: a 100% local conversion
Offcloud is an online converter with a twist: the conversion itself never touches a server. Using WebAssembly and canvas technology built into modern browsers, your WEBP file is decoded and re-encoded as a PNG entirely on your own device. Nothing is uploaded, nothing is stored online, and nothing is kept once the conversion is done.
This local approach makes privacy the default rather than a promise, which matters when you are converting screenshots, client assets, or personal photos. It also means there is no server-imposed file-size limit: the only constraint is your device's memory, and very large images simply take a little longer. Everything is free, with no account, no signup, and no watermark, on desktop and mobile alike.
Quality, file size, and honest limits
PNG is lossless, so the conversion preserves every pixel your WEBP contains, including any transparent areas. Keep one thing in mind, though: a conversion can never improve the original. If the WEBP was saved with heavy compression, those artifacts are part of the image, and the PNG will reproduce them faithfully—no better and no worse.
Expect the PNG to be noticeably larger than the WEBP; that is the normal price of a lossless, universally compatible format, not a defect. A practical habit: keep the original WEBP if storage space matters, and use the PNG wherever compatibility is required. Finally, make sure you only convert images you own or have the right to use.
Conversion steps
- Open Offcloud in your browser; there is no account to create and nothing to install.
- Select your WEBP image or simply drag and drop it onto the page.
- Choose PNG as the output format: the conversion runs right in your browser, and nothing is uploaded.
- Download your PNG file and use it anywhere, from older software to the pickiest upload forms.
Frequently asked questions
Will the PNG keep the transparency of my WEBP image?
Yes. PNG fully supports alpha transparency, so logos, icons, and cutout images keep their transparent background after conversion. Nothing is flattened onto a white background.
Why is my PNG larger than the original WEBP file?
WEBP was built for aggressive compression on the web, while PNG is a lossless format that prioritizes fidelity and compatibility over file size. A bigger file after conversion is completely normal and does not mean anything went wrong.
Are my WEBP images uploaded to a server during the conversion?
No. The WEBP to PNG conversion runs 100% locally in your browser, so your images never leave your device. Nothing is stored online and nothing is kept after the conversion finishes.
Is converting WEBP to PNG with Offcloud really free?
Yes, completely. There is no signup, no account, no watermark on your PNG, and no hidden premium tier. You can convert as many WEBP images as you need.
Is there a size limit on the WEBP files I can convert?
There is no server-imposed limit, because there is no server involved. The only practical constraint is your device's memory, so a very large WEBP image will simply take a bit longer to convert.
