About this tool
Review image-loading exports before launch so critical images are not deferred, non-critical assets are not over-prioritized, and Core Web Vitals risk stays controlled.
Image Lazy Loading Checker is built for people who need to validate image loading directives and priority hints for seo performance without leaving the browser. Review image-loading exports before launch so critical images are not deferred, non-critical assets are not over-prioritized, and Core Web Vitals risk stays controlled. On this page, the main job is narrow and practical: parses rows in url|image|loading|fetchpriority|context|size format and normalizes page urls with an optional base url, then flags lazy-loaded critical images, eager below-fold images, high-priority misuse, and directive conflicts.
- Parses rows in URL|image|loading|fetchpriority|context|size format and normalizes page URLs with an optional base URL.
- Flags lazy-loaded critical images, eager below-fold images, high-priority misuse, and directive conflicts.
- Supports configurable below-fold eager payload budgets and per-page high-priority limits for practical remediation triage.
How to use Lazy Loading Checker
Enter page URLs, metadata, markup, or audit exports into the tool above, inspect the result, and share clear recommendations you can push back into templates or CMS fields. If you are checking an edge case, start with "What input format does this image lazy loading checker expect?" and verify the output against that scenario.
When this tool is useful
- Audit loading and fetchpriority directives before launching templates, migrations, or performance-focused releases.
- Catch lazy-loaded hero/LCP images that can delay rendering and hurt Core Web Vitals.
- Prioritize non-critical images still marked eager or high-priority when they should defer.
Practical tips
- Keep above-fold and LCP images eager with clear high fetch priority, then lazy-load non-critical media by default.
- Set a byte budget for eager below-fold assets so accidental template regressions are easier to catch.
- Limit per-page high-priority images to only the truly critical visual assets to avoid resource contention.
