PNG to WebP

Convert PNG images to WebP in your browser, keeping transparency, for smaller logos and graphics on the web. Nothing is uploaded.

Transparency is kept. Converted in this tab, never uploaded.

80 to 90 looks the same as the original for photos.

Your file stays on your device

Your browser opens and processes the file itself. It is never uploaded, to Sellstamp or anyone else, and nothing is kept after you close the page.

Selling images?

Photos, templates, presets or artwork: Sellstamp gives them a storefront and delivers the files automatically after payment. Open a free store

How to use it

  1. Choose or drop your PNG images.
  2. Pick the quality.
  3. Convert and download.

Your images are not uploaded

Your browser opens the image, does the work in this tab, and saves the result back to your device. Nothing is sent to Sellstamp or anyone else, so there is no upload to wait for and no copy on a server afterwards.

Transparency and size

WebP keeps transparency, so a PNG logo stays transparent. Google reports lossless WebP 26% smaller than PNG; this tool saves lossy WebP at the quality you set, which is usually smaller still. For a logo with sharp edges, use a high quality (90 or more) so edges stay clean.

Questions

Is transparency kept?

Yes. Transparent areas stay transparent in the WebP.

Will edges stay sharp?

At high quality, yes. Lower qualities soften the edges of text and flat graphics first.

Which browsers can save WebP?

Chrome, Edge and Firefox. Safari can display WebP but not save it from a web page.

Can I convert a batch?

Yes, up to 100 images, downloaded as a zip.
