WebP is what most modern websites now serve, so images saved from the web increasingly arrive in a format that Photoshop, PowerPoint, and plenty of desktop software still refuse to open. Converting to PNG fixes that while preserving every pixel exactly — PNG is lossless, so nothing is degraded in the process, and any transparent background survives intact.

Before you convert: PNG does not support animation. If your WebP file is animated, only the first frame is converted.

How to convert WebP to PNG

  1. Select your WebP files. Click "Choose WebP files" or drag them onto the box above. You can select as many as you like at once.
  2. Wait for the conversion. Each file is converted to PNG on your own device. Nothing is uploaded, so it finishes as fast as your hardware allows.
  3. Download the results. Download files individually, or take them all at once as a single ZIP archive.

About WebP files

WebP was released by Google in 2010 to cut image weight on the web, and it does: it typically produces files 25–35% smaller than an equivalent-quality JPG. It supports both lossy and lossless modes, full transparency, and animation, making it the one format that covers everything JPG, PNG, and GIF do individually. Its weakness is not technical but social — plenty of desktop software still refuses to open it.

Where they come from: Images saved from websites — most modern sites now serve WebP.

Drawbacks of WebP

  • Many desktop apps and older programs still cannot open it
  • Some print shops and marketplaces reject WebP uploads

Why convert to PNG?

PNG was created in 1996 as a patent-free replacement for GIF, and it became the standard for anything that needs a transparent background or pixel-perfect fidelity. Its compression is lossless, so a PNG is an exact reproduction of the original — no artefacts, no generational loss when re-saved. That precision is why it is the format of choice for logos, screenshots, icons, and UI assets.

  • Full alpha transparency
  • Lossless — no quality degradation, ever
  • Sharp text, lines, and flat colour stay crisp

Support: Universal, including transparency.

Common questions

Are my files uploaded to a server?

No. The conversion runs entirely inside your browser using your own device’s processor. Your WebP file is never transmitted, never stored, and never seen by us — you can disconnect from the internet after the page loads and it will still work.

Is there a file size or daily limit?

There is no daily limit and no account required. Because your device does the work rather than our server, we have no per-conversion cost to recover. The practical ceiling is your device's available memory — very large files on older phones may fail, in which case convert them in smaller batches.

Can I convert several WebP files at once?

Yes. Select or drop as many WebP files as you like and they are converted one after another, then offered as individual downloads or a single ZIP.

Why can I not open WebP files in my photo editor?

WebP is a web-first format. Browsers all support it, but a great deal of desktop software — including older versions of Photoshop and most default photo viewers — has never added support. PNG is understood everywhere.
