How good it looks, not how big it gets. Try 80 to 90 for screenshots.

Makes the image smaller in pixels first. This saves more than quality does.

EXIF is dropped. Output is always tagged sRGB.

How it works

  1. 01

    Add your PNGs

    Drop, paste or pick files. The page uploads nothing, and the queue stays in this tab.

  2. 02

    Set quality

    82 is a good default. Turn on Lossless WebP when edges and text must stay exact.

  3. 03

    Convert and download

    Take files one at a time, or download the whole batch as a single .zip.

Why convert PNG to WebP

Google made WebP to replace both PNG and JPG on the web. In Google's own tests, lossy WebP came out 25 to 34% smaller than a JPG of the same quality. Lossless WebP was about 26% smaller than the same PNG. Transparency survives either way, so screenshots, interface exports and logos get smaller with no visible change.

Quality 82 is a good default for photographs. Above 90 the file grows quickly for very little gain. Below 70, flat gradients start to show bands. Lossless WebP ignores the slider, and it is the right choice for line art, text and pixel-exact artwork.

Frequently asked questions

Is there a limit on how many images I can convert?
No. There is no size cap, no daily quota and no queue limit. The tool runs on your machine, so the only limit is memory. Large batches convert one file at a time to keep the tab responsive.
Do my files get uploaded anywhere?
No. Your browser decodes and re-encodes the images itself, so the files never leave your device.
Does WebP keep PNG transparency?
Yes. WebP stores a full 8-bit alpha channel, so soft edges and partial transparency survive the conversion.
Will I lose image quality?
Lossy WebP drops a small amount of detail to make a much smaller file. Turn on Lossless WebP when every pixel must stay exact.
What happens to EXIF data and colour profiles?
The tool drops EXIF and does not copy a colour profile from the PNG. Your browser re-encodes the pixels and tags the WebP as sRGB. For a web image that is usually what you want, and you cannot change it here.
Can I convert an animated PNG?
Only the first frame. Animated WebP needs an encoder the browser does not offer, so an APNG comes out as a still image.
Can I convert WebP back to PNG?
Yes. Use the WebP to PNG converter when you need lossless editing or wider software support more than a small file.
Does this work offline?
Yes. Once the page has loaded, conversion carries on with no network connection.
