About this free responsive image source inspector tool
List image srcset, sizes and loading declarations for image-delivery review. Developer utilities inspect or transform data locally rather than contacting the address or service shown in your input. Use fictional samples while checking a format, keep credentials out of shared screenshots and validate the result against the receiving system. Successful parsing does not establish trust, security or schema correctness.
A practical example
A concrete example uses page html source: <html lang="en"><head><title>Guide</title></head><body><h1>Guide</h1><h3>Details</h3><a href="/tools">Tools</a><a href="https://example.org">Example</a><img src="photo.png" alt="Example photo"><p>Read this guide.</p></body></html>. The result is photo.png | srcset: (none) | sizes: (none) | loading: (default).
Before you rely on the result
Source-only check of pasted HTML; no page is visited. It does not establish Google indexing, rankings or search-result eligibility.
