Faster pages with smaller images

Images are usually the heaviest part of a web page. WebP files are typically 25–35% smaller than JPGs that look the same, so converting your photos speeds up loading, especially on mobile connections, and can improve your Core Web Vitals and Lighthouse scores.

Use JPEG to WebP as a WebP converter for websites, where smaller images load faster.

  • 80–85% quality is a good default for website photos: visually clean and very small.
  • 90% or higher for photography portfolios where fine detail matters.
  • Resize first: a 4000-pixel photo shown 800 pixels wide wastes bandwidth. Resize image can bring it to the size your layout needs.

Browser support

Every current browser, including Chrome, Safari, Firefox, Edge and Samsung Internet, displays WebP. Creating WebP files requires a browser that can encode them; Chrome, Edge and Firefox can. If yours can’t, Atifo tells you rather than giving you a mislabelled file.

Keep your originals

WebP is a delivery format. Keep the original JPGs for printing and future editing, and upload the WebP versions to your site.

Batch conversion

Convert a whole gallery at once, up to 50 images, and download them as a ZIP.
