PNG to WEBP Converter

Convert PNG to modern WebP for much smaller images that keep transparency - instant, in your browser, no upload.

About this converter

WebP is a modern image format that compresses far better than PNG while still supporting transparency. Converting PNG to WebP can dramatically reduce file size - often by half or more - which makes web pages load noticeably faster.

It is the go-to move for optimising website images. WebP is supported by all current browsers; if you need a file for older software that does not read WebP, keep a PNG copy too.

PNG to WebP: good to know

Big savings: WebP is often 50% or more smaller than the equivalent PNG.
Transparency is preserved, unlike a PNG-to-JPG conversion.
Supported by all modern browsers; keep PNG for very old software that cannot open WebP.

How it works

Drop your file(s) in the box above (or click to browse).
Make sure WebP is selected as the output.
Click Convert, then Download your file.

Frequently asked questions

How do I convert PNG to WebP?

Drop your PNG (or several) above, choose WebP as the output, and click Convert, then Download. It is instant and nothing is uploaded.

Does WebP keep transparency?

Yes. Unlike JPG, WebP supports transparency, so transparent areas in your PNG are preserved.

How much smaller will the WebP be?

It varies by image, but WebP is commonly 50% or more smaller than the same PNG, which speeds up page loads.

Is WebP widely supported?

All current browsers support WebP. Some older desktop software does not, so keep a PNG copy if you need maximum compatibility.

Are my images uploaded?

No. Conversion runs in your browser, so your files never leave your device.
