Drop WebP files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Save the QOI, or download everything as one ZIP if you converted several files.
The WebP to QOI converter is part of this page and runs inside your browser. Your images are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
WebP is still rejected by plenty of desktop apps, older software and upload forms. QOI is lossless and extremely quick to read and write. WebP is at home in images on websites; QOI is the usual choice for game textures and pipelines that need very fast encoding.
QOI holds a single still image, so an animated WebP does not stay animated. The defaults suit most files. Under Options you can resize the result.
If the WebP is animated, only its first frame is converted and the result is a still picture. QOI stores every pixel and the alpha channel exactly; the encoder is a small WebAssembly module that downloads the first time and is cached.
WebP is Google's image format for the web. It is typically a quarter to a third smaller than JPG or PNG at similar quality and supports both transparency and animation. Browsers handle it well; older editors, printers' portals and some messaging apps do not.
Opens in All current browsers; many older desktop apps and upload forms do not accept it
WebP converterQOI is a lossless image format with a specification short enough to read in a few minutes. It compresses far less than PNG but encodes and decodes many times faster, which is why game developers and tool authors like it. Support in everyday apps is thin.
Opens in IrfanView, XnView, many game engines and graphics tools; no browsers or phones

No. The WebP to QOI conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
No further quality is lost: QOI stores the decoded pixels exactly. The result is identical in content.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the WebP file, press Convert and save the QOI. There is nothing to install.
Pictures of up to 120 megapixels are accepted (for example 12,000 by 10,000 pixels); a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
