About this tool
Review image delivery exports before deployment so critical/LCP images get explicit high-priority treatment while non-critical assets avoid over-prioritization that can weaken render performance.
This SEO tool is built for pre-publish QA and implementation support rather than vague optimization advice. It helps teams check one search-facing signal cleanly before a page, template, or release goes live.
- Parses rows in URL|image-url|fetchpriority|loading|is-lcp|status|context|bytes format and normalizes relative URLs with an optional base URL.
- Flags missing or invalid fetchpriority values, critical images not marked high, and conflicting combinations like fetchpriority=high with loading=lazy.
- Surfaces page-level critical priority-risk byte overflow and high-priority over-allocation to focus fixes on the strongest LCP opportunities first.
How to use Image Fetchpriority Checker
