About this tool

Conversion happens in the page: the PNG file is decoded by your browser, redrawn, and re-encoded as WEBP. Nothing is uploaded, so there is no queue, no size limit imposed by a server, and no copy of your image on someone else's machine.

WebP keeps transparency and is far smaller than PNG for photographs. For flat graphics the saving is smaller.

The image's pixel dimensions are unchanged — only the format and file size differ. To change the size as well, use the image resizer afterwards.

Common uses

  • Sending an image to software that will not accept PNG.
  • Reducing the file size of a PNG image.
  • Standardising a set of images on one format.

Frequently asked questions

Is my PNG file uploaded?
No. It is decoded and re-encoded by your browser on your device, which is why there is no wait and no size cap.
Does converting PNG to WEBP lose quality?
Slightly, since the output format is lossy. At 90% quality the difference is rarely visible at normal viewing size.
Are the dimensions changed?
No. The image keeps its pixel dimensions; only the encoding changes. Use the image resizer to change dimensions.
