WebP is a modern image format supported by every current browser. It typically makes PNG graphics 25–35% smaller and photos even more, while still supporting transparency. That makes it the go-to format for fast-loading websites.

Use it for website images, product photos and graphics where page speed matters. Keep a PNG copy for apps or people that don't support WebP yet.

How to use the PNG to WEBP tool

  1. Add your PNG files

    Drag them onto the box, click Choose file, or paste an image. You can add up to 10 at once on the free plan.

  2. Pick the quality

    Leave the quality around 90% for photos, or lower it to make smaller files.

  3. Convert and download

    Click Convert to WebP. Download each file, or everything at once as a ZIP.

Tips

  • 90% quality is a good default; try 80% for large photos.
  • Transparency is kept, so logos stay clean on any background.
  • Some older desktop apps can't open WebP. Keep the original too.

Frequently asked questions

Is WebP supported everywhere?

All modern browsers (Chrome, Safari, Firefox, Edge) display WebP. Some older desktop software and a few upload forms still expect JPG or PNG.

Does WebP keep transparency?

Yes. Unlike JPG, WebP supports transparent backgrounds.

Why didn't conversion work in my browser?

Creating WebP files needs a browser that can encode WebP. Chrome, Edge and Firefox can; if yours can't, we'll tell you and you can use PNG to JPG instead.

Are my images uploaded anywhere?

No. The conversion runs entirely in your browser using your device's own image engine. Your files are never sent to Scanlexa or anyone else, which is why it also works offline once the page has loaded.
