About This Tool

Why use this tool?

WebP delivers 26–34% better compression than PNG at the same visual quality. Google developed it specifically for the web, and their PageSpeed Insights tool flags PNG images and recommends WebP as a direct replacement. Every PNG you convert to WebP makes your page load faster.

When should you use it?

Before uploading images to any website or CMS
When Google PageSpeed flags your images
To reduce bandwidth while keeping transparency
Before uploading to WordPress, Shopify, or Squarespace

How does it work?

ConvertPix uses the HTML5 Canvas API built into every modern browser to process your images entirely on your device. Your files are read from your local storage, processed in browser memory, and saved back to your downloads. They never travel over the internet — not even a single byte.

Is it free?

Yes — completely and permanently free with no limits, no watermarks, and no account needed. ConvertPix is supported by the display advertising you see on this page.
