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
Drop the PNG in
It is read in the page; nothing is sent anywhere.
-
2
It is encoded as WebP
Transparency is carried across; quality is kept at 92%.
-
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.
