Scalpel Images finds every image on a page, including the hidden ones in lazy-load attributes, srcset, CSS backgrounds, and canvas, then filters, selects, and bulk downloads them with a rename pattern.

What it does

  • Even lazy-loaded and canvas imagesFinds images from eight sources: img tags, lazy-load attributes, srcset and picture variants, CSS backgrounds, same-origin canvas, preload hints, and Open Graph and Twitter metadata.
  • Largest-variant selectionFor responsive images it picks the largest variant from srcset and picture, and it probes unknown-size images so minimum-width filters still work.
  • Filter by size, weight, type, or sourceNarrow by minimum width and height, transferred weight in KB, type (jpg, png, gif, webp, svg, avif), discovery source, or URL substring, and hide near-duplicate images. The grid re-renders live.
  • Bulk download with patternsSelect the images you want and rename them with free tokens for name, extension, width, height, format, index, host, and date, then organise downloads into subfolders.
  • Next-gen advice and right-clickIt flags JPEG, PNG, and GIF images that would be smaller as WebP or AVIF, advisory only, so nothing is re-encoded. A right-click menu grabs a page's images or downloads a single image, and a ? on each control links to the glossary.
  • Private by designDiscovery runs locally and Chrome handles the actual downloads. No page content is sent to a server, and there is no account or paywall.

Frequently asked questions

Does it find lazy-loaded and background images?

Yes. It discovers images from eight sources, including lazy-load attributes, srcset and picture variants, CSS backgrounds, same-origin canvas, preload hints, and Open Graph and Twitter metadata.

Can I rename files during a bulk download?

Yes. Apply a pattern with free tokens for name, extension, width, height, format, index, host, and date, and send the downloads into subfolders.

How do the size filters work on images the page never rendered?

The popup probes unknown-size images in the background, so a minimum width or height filter still applies to them.

Does my page data leave the browser?

No. Discovery runs locally, and Chrome handles the actual file downloads. Nothing is sent to a server, and there's no account or paywall.

Is it free?

Yes. Scalpel Images is free.
