Website image checker

Page URL
Enter a public page URL.

How it works

  1. 1Paste a public HTTP or HTTPS page URL.
  2. 2ImgShrink reads the public HTML and up to 40 public image resources from that page.
  3. 3Review image size, dimensions, format, alt, width and height, loading, srcset and next-step repair links.

Privacy and limits

  • This checker reads only the public page URL you enter and public image resources referenced by that page.
  • It does not crawl the whole site, follow links, log in, save URLs, save HTML or keep an image history.
  • The report is a machine-readable image precheck, not a full SEO audit, Lighthouse report or Core Web Vitals measurement.

Website image check scope

The checker reads one public page and inspects image resources referenced in the HTML, including normal image tags, Open Graph image and favicon signals.

It is designed for publishing checks before fixing images, not for crawling a whole site or measuring Core Web Vitals.

Common use cases

  • Checking a blog post before publishing
  • Finding oversized images on a landing page
  • Confirming alt text, dimensions and responsive image markup

Result notes

  • Image details depend on whether each public resource can be fetched and decoded.
  • A missing alt value may be acceptable for decorative images, but content images need useful text.
  • Use the linked repair tools to compress, resize, convert or recheck specific assets.

Original test sample

  • Check a public page with JPG, PNG and WebP images and confirm the summary reports readable image count, missing alt and oversized files.
  • Check a page without og:image or favicon links and confirm those signals are reported separately.

Frequently asked questions
