Convert PNG to WebP

Convert PNG images to modern, smaller WebP format.

How to use the PNG to WebP

  1. Add your PNG files

    Drop in one image or a batch. They are decoded in your browser and never uploaded.

  2. Pick a quality level

    Higher quality means a larger file. The default is tuned to be visually indistinguishable from the source for most images.

  3. Download the WebP files

    Compare the new file size against the original, then save the results.

About the PNG to WebP

WebP is the format to reach for when a PNG is slowing a page down. At comparable visual quality it typically lands 25-35% smaller, and on screenshots and flat-colour graphics, the images most likely to be PNGs in the first place, the saving is often larger still. On a page carrying a dozen images that is the difference between a fast Largest Contentful Paint and a Core Web Vitals warning in Search Console.

Browser support stopped being a reason to hesitate years ago. Chrome, Firefox, Safari and Edge all handle WebP, as do Android and iOS, so for web delivery you can generally serve it directly rather than maintaining a PNG fallback. Transparency survives the conversion intact, because WebP has a real alpha channel just as PNG does.

The conversion runs entirely in your browser through the same encoder your browser uses to save WebP elsewhere, so there is no upload, no queue and no per-file limit. Convert a single hero image or a whole folder of interface assets, check the size saving before you commit, and download the results.

Frequently asked questions

Why convert PNG to WebP?
WebP usually produces files 25-35% smaller than PNG at comparable quality, which directly improves page load time and Core Web Vitals.
Do all browsers support WebP?
Yes. Every current major browser supports WebP, including Chrome, Firefox, Safari and Edge.
Does WebP keep transparency?
It does. WebP supports an alpha channel just like PNG, so transparent areas survive the conversion.
