PNG to WebP

Cut a PNG down for the web, transparency intact — never uploaded.

How it works

Three steps, and nothing leaves your device.

  1. 1

    Drop the PNG in

    It is read in the page; nothing is sent anywhere.

  2. 2

    It is encoded as WebP

    Transparency is carried across; quality is kept at 92%.

  3. 3

    Download the WebP

    Noticeably smaller, and every current browser reads it.

The one conversion that costs you almost nothing

  • Smaller with the transparency intact. This is the conversion PNG-heavy sites are looking for: WebP has a real alpha channel like PNG, so logos, icons and cut-outs keep their transparent background while the file drops substantially.
  • Browser support is no longer a reason to hesitate. Every current browser reads WebP. The remaining risk is not the browser, it is software outside it — some desktop apps and upload forms still refuse WebP, which is why the reverse conversion exists too.
  • Page speed is the real payoff. Images are usually the heaviest thing a page loads, and this is the cheapest way to cut that weight. It is one of the few changes that improves Core Web Vitals without touching layout or code.
  • Keep the PNG as the master. WebP at 92% is lossy. It is the right file to publish, not the right file to keep editing — do your work on the PNG and export the WebP each time.

Frequently asked questions

Is transparency kept?

Yes. WebP has a full alpha channel, exactly like PNG.

How much smaller is it?

Typically a substantial reduction at the same visible quality. The exact figure depends on the image.

Do all browsers support WebP?

Every current browser does. Some non-browser software still does not.

Is my image uploaded?

No. It is converted in your browser.
