How it works

A static WebP is decoded locally, including transparency, and written as a new 8-bit PNG. PNG encoding is lossless at the pixel level for the decoded input; OxiPNG then rearranges the file representation without changing those pixels.

The route is useful when an editor, CMS or document workflow does not accept WebP. Validation confirms the PNG signature and dimensions before download.

01

Formats and settings

  • PNG is fixed as the output and uses optimisation level 2 by default.
  • The source dimensions and alpha channel are retained.
  • Resize first when the receiving tool also needs fewer pixels; PNG alone usually increases the byte size.
02

A concrete example

A 1200×800 WebP logo with transparency can become a 1200×800 PNG accepted by an older presentation tool. The output may be several times larger because PNG prioritizes exact decoded pixels rather than photographic compression.

03

Know before you start

  • Animated WebP is rejected.
  • Converting a lossy WebP to PNG cannot restore detail discarded by the original WebP encoder.
  • PNG output may be much larger, especially for photos and gradients.

FAQ / 03

Frequently asked questions

Does PNG restore the original camera image?

No. It preserves the pixels decoded from the WebP, not detail already lost before this conversion.

Will transparency remain?

Yes, static WebP alpha is carried into the PNG output.

Why run PNG optimisation after encoding?

OxiPNG searches for a smaller valid PNG representation without altering the decoded pixels.
