PNG ↔ WebP Converter — free online tool

Lossless PNG screenshots can become smaller WebP files; convert back when a platform insists on PNG.

When to use PNG ↔ WebP Converter

Shrink UI screenshots and transparent graphics for the web without flattening transparency.

Good for email attachments, CMS uploads, and faster page loads without installing desktop software.

What PNG ↔ WebP Converter does not do

Transparency usually survives WebP, but some older apps still reject WebP. Not a sprite-sheet packer.

How to use PNG ↔ WebP Converter

Upload PNG or WebP on the PNG ↔ WebP Converter.
Confirm whether you need lossless PNG again or smaller WebP delivery.
Convert locally and inspect transparency in the preview if available.
Download when the visual check looks correct.

Practical tips

PNG → WebP can dramatically shrink screenshots while keeping text readable.
Convert back to PNG only when a platform refuses WebP uploads.
Transparency is preserved both ways, so logos keep their clear background.

Example

Shrink a transparent UI icon PNG to WebP for a web app asset folder.
