Drop WebP files here

or — multiple files welcome. Nothing is uploaded; conversion happens on your device.

Files are processed entirely in your browser — never uploaded, never stored. Large photos convert in about a second each; the first HEIC file loads a small decoder module.

Runs fully in your browser — images are never uploaded or stored.

How it works

Converting WebP to PNG is the lossless route: pixels are preserved exactly and transparency survives, at the cost of larger files. It is the right choice when the image is headed into an editor or a workflow that demands PNG.

  1. Drop the WebP files above.
  2. No quality slider here — PNG is lossless, so there is nothing to trade away.
  3. Download the PNGs; alpha transparency carries over intact.

WebP vs PNG

WebP PNG
Compression Lossy or lossless Always lossless
File size Much smaller Larger
Transparency Yes Yes
Best for Web delivery Editing, logos, screenshots

Tip: If the PNG output feels heavy, run it through the PNG compressor afterward — palette quantization typically halves screenshot-style images.

Frequently asked questions

Does WebP to PNG preserve transparency?

Yes — PNG supports full alpha transparency, so transparent WebP images convert cleanly. PNG is lossless, so no image quality is lost either; files just get larger, since PNG compresses less aggressively.

Why is my PNG bigger than the WebP was?

Expected: WebP is a newer, more efficient format. You’re trading file size for universal compatibility and losslessness. If size matters more than compatibility, keep WebP.

Are my images uploaded to a server?

No. Conversion runs entirely in your browser using its built-in image engine — files never leave your device, which also makes it faster than upload-based converters and safe for private photos.
