PNG to WebP
Turn a PNG image into a WebP — instantly, privately, in your browser.
Your image is processed entirely in your browser — it is never uploaded to a server.
About this tool
The conversion is a re-encode: your browser decodes the PNG and writes a fresh WebP at full size and high quality (92%). Nothing is resized or cropped. Transparency is preserved. The WebP is written at 92% quality, which is visually lossless for most images.
WebP typically makes files 25–35% smaller than the same PNG — the reason websites use it. Converting your PNGs is a quick win before uploading them to a site or sending them anywhere size matters.
How to use it
- Choose a PNG image.
- Press Convert to WebP and save the result.
Frequently asked questions
Is my image uploaded?
No. The conversion runs in JavaScript in your browser; the file never leaves your device.
Does converting lose quality?
Converting to PNG or WebP (lossless mode off) — PNG is fully lossless. JPG and WebP re-encode with a small quality cost at the 92% setting, invisible in normal use. Converting between lossy formats repeatedly does add up, so keep your original.
Which browsers does this work in?
Any modern browser. Decoding depends on the browser supporting the source format — all current Chrome, Edge, Firefox and Safari versions handle WebP and AVIF.
