About this tool

PNG is a lossless format with full transparency support. WEBP is a modern format that supports lossy and lossless compression plus transparency and is usually smaller than PNG or JPEG. Choosing between them depends on where the image will be used: PNG is common for logos, screenshots, icons and graphics with sharp edges, while WEBP suits fast-loading web pages.

WEBP is lossy, so you can set the quality: a lower value gives a smaller file with some loss of detail.

The conversion uses your browser's own image engine, so nothing is uploaded and there is no file size limit beyond your device's memory. Very large images over 100 megapixels are refused to avoid freezing the page.

Frequently Asked Questions

Will I lose quality converting PNG to WEBP?
Some detail is lost because WEBP uses lossy compression. At 90% quality the difference is usually invisible.
Is transparency kept?
Yes, WEBP supports transparency and the transparent areas of your PNG stay transparent.
Are my images uploaded to a server?
No. The conversion runs entirely in your browser and the files never leave your device.
Can every browser open WEBP?
All current versions of Chrome, Edge, Firefox and Safari support WEBP. Very old software may not.
