Why convert PNG to WebP

PNG is the usual format for screenshots, logos, product photos on a clear background and images exported from design apps. It keeps every pixel, which makes big files, especially for anything photo-like. WebP, an image format made by Google for the web, keeps transparency like PNG but usually stores the same image in less space, so web pages load faster. It’s a common fix when a speed test or a website builder flags large PNGs.

How to convert

  1. Choose up to 30 PNG images, each up to 50 MB. You can also drop them on the box or paste a screenshot.
  2. Leave the quality at 90, or change it (below).
  3. Press Convert to WebP, then download each file, or all of them together as a ZIP.

Choosing the quality

The number, from 1 to 100, sets how much detail the WebP keeps. 90, the default, is set higher than for photos because PNGs are often graphics and screenshots, where sharp edges and text show any softening first. For a photo saved as PNG, 80 to 85 usually looks very close and saves more. Each result shows its size, so you can compare and try again. Transparency is kept at any quality.

When PNG is still the better file

WebP isn’t accepted everywhere yet: some older programs, print services and upload forms want PNG or JPG. And a tiny icon or a flat-color logo may already be smaller as a PNG. Keep the PNG as your original, and use the WebP where file size matters, such as on your own website.

Safari, iPhone and iPad

Safari, and the other browsers on an iPhone or iPad that use Safari’s engine, can show WebP but can’t make it. When the page finds your browser can’t, it loads a WebP encoder of its own (libwebp, the reference WebP library) the first time you convert. It runs on your device, and your images never leave it.

  • Names: logo.png becomes logo.webp. Size in pixels stays the same. A file that can’t be read gets its own message, and the rest still convert.

Frequently asked questions

Does WebP keep the transparent background?
Yes. See-through areas stay see-through, soft edges and shadows included. That’s the main advantage of WebP over JPG for graphics.
Why is my WebP not much smaller than the PNG?
Simple graphics with a few flat colors are already very compact as PNG. WebP saves the most on photos and detailed images saved as PNG. If a result isn’t smaller, keep the PNG.
Does it work in Safari?
Yes. Safari can show WebP but can’t make it, so there this page loads a WebP encoder of its own the first time you convert. It runs in your browser like the rest.
Are my images uploaded?
No. Your own browser does the conversion, and the WebP files are saved straight to your device.
