PNG to WebP

Convert PNG images to WebP to cut page weight while keeping transparency — the format modern sites use for logos, icons, and product shots.

Runs entirely in your browser. Your files never leave your device.

The web format that keeps your alpha channel

WebP was built to replace both JPG and PNG on the web, and unlike JPG it supports a full alpha channel. That combination is what makes this conversion useful: a logo, an icon, or a product cutout can drop to a fraction of its PNG size and still sit cleanly on any background colour. For photographic PNGs the saving is dramatic, frequently ninety percent or more, and even for flat graphics it is usually worth twenty to thirty percent.

Support is no longer a reason to hesitate. Every current browser renders WebP, including Safari since version 14, and search engines index the images normally. The remaining friction is all outside the browser: some desktop editors, older office suites, and upload forms with extension whitelists still reject the format. Keep the PNG as your working copy and treat the WebP as the file you ship to the web.

How to convert PNG to WebP

  1. 1

    Add the PNG files

    Drop in up to 20. This is the conversion to run over an entire folder of site assets at once.

  2. 2

    Set the WebP quality

    WebP keeps the alpha channel, so transparent PNGs stay transparent. At quality 80 most PNGs drop by well over half with no visible change.

  3. 3

    Download the WebP

    Every browser released in the last several years reads WebP. Swapping PNG assets for WebP is one of the cheapest page-weight wins available on an image-heavy site.

PNG to WebP questions

Yes. WebP carries a full alpha channel, so transparent and semi-transparent pixels survive the conversion untouched. That is the main reason to choose WebP over JPG for logos, icons, and cutouts.

For photographs, typically eighty to ninety-five percent smaller at the default quality. For flat graphics and screenshots the gap narrows to something like twenty or thirty percent, because PNG already compresses that kind of image efficiently.

All of them, in every version released in the last several years — Chrome, Edge, Firefox, Opera, and Safari from version 14 onward. Browser support stopped being the argument against WebP a long time ago; desktop software is where the gaps remain.

It can be either. This converter writes lossy WebP with a quality slider, which is what makes the files so much smaller than the PNG. When you need a pixel-exact copy, keep the PNG — that is what lossless is for.

On a website, yes for photographs and large graphics. Keep PNG for tiny icons where the saving is negligible, for files that will be edited again, and for anything users will download and open in software you cannot predict.
