PNG is the usual format for logos, icons, product cut-outs and interface screenshots because it keeps transparency and sharp edges. On a website, though, those PNGs are often the heaviest files on the page. WebP supports the same alpha channel and compresses far better, so converting is one of the simplest ways to speed up a page without changing how it looks.

How much you save depends on the picture. A photographic PNG, such as a product shot on a transparent background, often shrinks by 70-90% at quality 80-85. A flat logo or a screenshot with large areas of one colour shrinks less, and at very high quality the WebP can occasionally be close to the PNG size; the result card shows the exact change so you can decide. Transparent pixels stay transparent, including soft anti-aliased edges.

Every current browser displays WebP, as do WordPress, Shopify and most other site builders. Keep the original PNG as your master copy for editing, and publish the WebP. The conversion uses your browser's own WebP encoder, so nothing is uploaded; if a browser has no WebP encoder (some older Safari versions), the page tells you instead of producing the wrong format.

How to use it

  1. Drop a PNG file or click to browse.
  2. WebP is preselected. Set the quality: 80-85% suits photos and cut-outs; use 90% or more for screenshots with small text.
  3. Click Convert to WebP and compare the new size with the original.
  4. Download the .webp file and use it on your site; keep the PNG as the editable original.

Frequently asked questions

Does WebP keep PNG transparency?

Yes. WebP has a full alpha channel, so transparent and semi-transparent pixels are preserved.

Is WebP lossless like PNG?

WebP has both lossy and lossless modes. The quality slider drives the browser's lossy encoder; at 90% and above the difference from the PNG is very hard to see. Keep the PNG as your editable master copy.

Why is the WebP not much smaller?

Simple graphics with few colours are already compact as PNG. The biggest savings come from photographic PNGs. Try a lower quality, or keep the PNG if the saving is small.

Can I use WebP in email?

Support in email clients is patchy; Outlook for Windows in particular does not show WebP. Use PNG or JPG for newsletters.

What if my browser cannot encode WebP?

The format button is disabled and the page explains why. Chrome, Edge, Firefox and current Safari can all write WebP.
