Free image tool

Convert WebP to PNG in your browser

Websites often serve images as WebP, and some apps and editors still cannot open them. This tool turns WebP images into PNG files on your device. Nothing is uploaded.

PNG is lossless and supports transparency, so the PNG keeps exactly the pixels of the WebP image, including transparent areas.

WebP to PNG

Your images are converted on this device and never uploaded.

WebP → PNG

Metadata such as the location, camera and date is not copied into the new file. Colors are converted to sRGB.

    How it works

    1. Leave OxiPNG on to make the PNG files smaller without changing any pixels, or turn it off for faster conversion.

    2. Choose your WebP files, or drop them anywhere on the page. Conversion starts right away.

    3. Download each PNG, or all of them as one ZIP file.

    Your browser decodes each WebP image in a background worker and writes it as a PNG. OxiPNG, compiled to WebAssembly, then recompresses the PNG without changing any pixels. The image is not sent anywhere.

    Questions

    What it does and what it does not

    Privacy, metadata, file limits and browser support.

    Are my images uploaded?

    No. The page and its encoders load from quireapps.com, and after that each image is read, converted and saved inside your browser tab. There is no analytics or tracking on this page. You can check this in your browser's developer tools, on the Network tab: converting an image makes no requests.

    Is transparency kept?

    Yes. PNG supports full transparency, so transparent and partly transparent areas stay as they were.

    Why is the PNG larger than the WebP file?

    Most WebP images on the web use lossy compression, which throws away detail you are unlikely to see. PNG keeps every pixel exactly, so photos come out several times larger. The PNG does not look better than the WebP; it is an exact copy of it.

    What about animated WebP files?

    Only the first frame is converted. This tool does not make animated PNG files.

    What happens to the metadata?

    It is not copied. The new file has no EXIF location, camera details or date taken. The EXIF orientation is applied to the pixels first, so the image keeps the way it was displayed. Colors are converted to sRGB and no color profile is written. To remove metadata without converting, use the EXIF remover.

    Are there limits?

    Each file can be up to 50 MB and 100 megapixels, and the list holds up to 100 files at a time. Safari on iPhone and iPad limits images to about 16.7 megapixels for this kind of processing, so larger images can fail there. Animated WebP files become a still image of the first frame. Files are converted one at a time.

    Which browsers does it work in?

    It is tested in Chrome. Current versions of Edge, Firefox and Safari should also work, but they have had less testing here.

    Is it free?

    Yes. There is no account, no sign-up, no watermark and no daily limit.
