What it does

Make web-ready images in bulk: WebP, AVIF and JPG at several widths, metadata removed, with a savings table, a zip download and ready srcset and picture code. Nothing uploaded.

Steps

  1. Choose images or drop them on the page. JPG, PNG, WebP, AVIF and GIF files work.
  2. Tick the Widths you want, from 480 to 2560. Images are never made larger than the original.
  3. Choose the Formats: AVIF, WebP, a JPG fallback, and PNG for transparent images.
  4. Set the Quality, the sizes attribute and the Image folder on your site, and press Redo with these settings if you change them.
  5. Compare Before and After, then press Download all (.zip).
  6. Copy the picture code for each image and paste it into your page.
