Are my images uploaded anywhere during conversion?

No, conversion happens entirely in your browser using the canvas API. Your WebP file is decoded and re-encoded locally, with no network request.

Will the PNG be larger than the WebP?

Almost always. WebP can use lossy compression and PNG cannot, so a photo that was 200 KB as WebP often becomes 1.5-2.5 MB as a PNG. The pixel data is identical — only the encoding differs.

Is transparency preserved?

Yes. PNG supports a full 8-bit alpha channel, so any transparent or semi-transparent pixels in the WebP carry over bit-perfect into the PNG output.

Why would I need PNG instead of WebP?

WebP is not universally supported in older email clients, some print pipelines, and legacy versions of Office and Photoshop. PNG is the safest interchange format when you do not control the destination software.

Does the converter handle animated WebP?

No. The canvas-based pipeline only captures the first frame of an animated WebP. For animated images, look for a dedicated WebP-to-APNG or WebP-to-GIF converter.

About this webp to png converter

A webp to png converter gives you a universally compatible, lossless version of any WebP image without touching a server. The output is a standard PNG file that opens in virtually every piece of software ever written — older versions of Microsoft Office, legacy CMS uploaders, print-shop pipelines, and email clients that have never heard of WebP.

The tool works entirely inside your browser. When you pick a file, the browser's native createImageBitmap API decodes the WebP pixel data. Pressing "Convert to PNG" draws those pixels onto an off-screen HTML canvas at the original width and height, then calls canvas.toBlob with the MIME type 'image/png'. The browser's own PNG encoder produces the output blob, which is handed back to you as a download link. Nothing is transmitted over the network at any point.

As a concrete example: a 480 × 360 WebP photograph at 180 KB will typically produce a PNG of around 1.2–2 MB after conversion, because PNG stores pixel data without lossy compression. The pixel values themselves are identical to what the browser would render for the original WebP — no quality is lost, just efficiency. Any transparent or semi-transparent pixels are preserved exactly, since PNG supports a full alpha channel.

This tool suits designers, developers, and anyone who needs to hand off an image to software that cannot read WebP.
