What changes when you convert WebP to PNG

Both formats are lossless, so the pixels in the PNG file are identical to the WebP source. Only the container and compression method change.
Transparency is preserved: PNG supports an alpha channel, so transparent backgrounds from WebP stay transparent.
PNG holds a single still image, so only the first frame of an animated WebP is kept.
PNG is less space-efficient than WebP, so expect the converted file to be larger than the original.
Compatibility improves: PNG opens in more browsers, apps and operating systems than WebP.

About WebP

WebP is Google's image format for the web. It supports lossy and lossless compression, alpha transparency and animation in a single format, usually producing smaller files than JPG or PNG.

Best for: Website images, e-commerce product photos, animated stickers and anything served to browsers where page speed matters.
Strengths: Smaller than JPG/PNG at similar quality, transparency and animation, supported by all modern browsers.
Limitations: Some older desktop software, print workflows and upload forms still do not accept it.

About PNG

PNG (Portable Network Graphics) is a lossless raster format created as a patent-free replacement for GIF. It supports full alpha transparency and up to 16 bits per channel.

Best for: Screenshots, logos, UI graphics, diagrams and any image that needs a transparent background or pixel-perfect edges.
Strengths: Lossless quality, full transparency, opens everywhere.
Limitations: Photos produce large files compared with JPG, WebP or AVIF.

Frequently asked questions

Is the WebP to PNG conversion really free?

Yes. ConverterUp is fully free, with no signup, no watermarks, and no daily quota for the WebP to PNG converter. We support the project through unobtrusive ads.

Are my WebP files uploaded to a server?

No. Conversion runs in your browser using WebAssembly. The WebP bytes never leave your device, and we have no upload endpoint at all.

What is the maximum file size?

For WebP input, the soft cap is 50 MB for images and 500 MB for video. Practical performance depends on your device's RAM.

Does converting WebP to PNG reduce quality?

No. Both formats are lossless, so every pixel is preserved exactly.

What happens to an animated WebP when converted to PNG?

PNG is a still-image format, so only the first frame is saved. To keep the motion, convert to MP4, WebM or an animated WebP instead.
