How to Convert PNG to WEBP (and Speed Up Your Website)

Page speed is a ranking factor, and images are usually the heaviest thing on a page. Switching from PNG to WEBP is one of the easiest wins available: WEBP files are typically 25–35% smaller at the same quality, and every modern browser supports them.

Convert PNG to WEBP in your browser

Use the free PNG to WEBP converter — drop your PNG in, pick a quality, and download the WEBP. It runs locally, so nothing is uploaded. Have JPG photos too? Use JPG to WEBP.

Why WEBP is smaller

WEBP uses more advanced compression than PNG and JPG while still supporting transparency (like PNG) and photographic detail (like JPG). For most images you get the same visual result in a much smaller file — which means faster loads, less bandwidth, and better Core Web Vitals scores.

Does WEBP lose quality or transparency?

No. WEBP keeps transparency just like PNG, and at sensible quality settings the difference is invisible to the eye. Keep the original PNG as your master file and export WEBP for the web.

Need to convert back?

Some older apps and editors still can't open WEBP. When that happens, use the WEBP to PNG converter to get a universally supported file again.

Squeeze out even more

For a full optimisation pass, run your images through the Image Compressor or Image Resizer first — serving images at the exact size they're displayed, in WEBP, is the combination that makes pages feel instant.
