About this tool
Review image exports before template releases so cross-origin images use the correct img crossorigin mode, expected ACAO/ACAC headers, and safe defaults for canvas-sensitive rendering flows.
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|crossorigin|acao|acac|status|context|bytes format and normalizes relative URLs with an optional base URL.
- Flags missing/invalid crossorigin attributes, anonymous/header mismatches, and use-credentials configurations that violate wildcard or ACAC requirements.
- Surfaces canvas-sensitive context risks plus per-page critical crossorigin-risk byte-budget overflow to prioritize the most impactful fixes.
