PNG to WebP Converter, Free and In Your Browser

PNG screenshots and UI assets are often larger than necessary for web delivery. WebP keeps transparency while shrinking transfer size.

Upload a PNG below and tune quality before download. Keep a PNG master archived if you still edit layers in design tools.

Format notes

When to use this output

PNG to WebP shines for web delivery of UI sprites, badges, and screenshots that need transparency but not PNG's byte weight. Many static site builds swap PNG icons for WebP to cut transfer size.

Transparency

WebP supports alpha like PNG. Soft shadows and anti-aliased icons stay intact, unlike JPG routes on this converter.

Quality

WebP can be lossy or lossless in theory; this tool uses the browser encoder with your Quality slider for a lossy WebP tuned for size.

File size

Transparent PNGs often shrink dramatically as WebP. Flat color panels compress especially well compared to PNG's deflate.

FAQ

Should designers keep a PNG master?

Yes. Archive PNG for editing; generate WebP for production. This page is a quick one-off without a build step.

Will colors shift?

At default quality, shifts are usually subtle. Raise quality if brand colors must match PNG exactly.

Max input size?

Up to 25 MB and 8000 px per side, same as other non-HEIC pairs here.
