Image Converter changes image formats right in your browser: WebP to PNG, JPG to WebP, PNG to JPG, whatever to whatever, and hands the files back in the format you actually wanted.

Your data

Your files never leave your device. Conversion happens in your browser.

Tips

A screenshot stuck as a WebP becomes a friendly PNG here, which is the format every other tool and form on the internet accepts.
Converting to WebP shrinks images for your website while keeping them sharp. Converting from WebP is for when some upload form refuses it.
