WebP to PNG Converter

Why anyone needs this

WebP works in every current browser, but plenty of software still refuses it: older desktop editors, some email clients, several content management systems and a long tail of print workflows. Converting to PNG is usually about compatibility with one stubborn application rather than anything about the image itself.

Transparency survives

Both formats support an alpha channel, so a WebP with a transparent background converts to a PNG with the same transparency intact. This is the main reason to choose PNG over JPEG as the target: JPEG has no alpha channel and would flatten the transparent areas onto a solid colour.

The file will get larger

PNG is lossless and stores every pixel exactly, so expect a substantial increase, often several times the original. If the source was lossy WebP, the PNG is faithfully preserving compression artefacts at full fidelity, which is why the size climbs without the image looking any better.

Quality is not recovered

A lossy WebP had information discarded when it was created. Converting to a lossless format locks in what remains; it does not restore what went. The PNG is a perfect copy of an imperfect image.

When PNG is the wrong target

For a photograph going back onto the web, converting WebP to PNG makes the page heavier for no visible benefit. If you need broader compatibility for a photograph, JPEG at quality 85 is far smaller and universally supported. Reserve PNG for images with transparency or sharp-edged graphics.

Converted locally

The browser canvas performs the conversion, so the file is never uploaded. Canvas processing also strips embedded metadata, which is usually welcome before sharing an image.
