What This Tool Does
Paste any HTML — a page template, a blog post, a product listing, or a CMS export — and the extractor finds every <img> tag and pulls out its src,alt, width, and height attributes. The stats bar immediately shows how many images are missing alt text, so you can prioritize accessibility fixes without manually scanning each tag. Export everything as a CSV for a spreadsheet-based audit workflow.
How to Use
- Paste your HTML markup into the input panel.
- Click Extract Images to scan and generate the results table.
- Check the stats bar: note the "Missing alt" count at a glance.
- Review each row for src, alt text, and declared dimensions.
- Use Copy All Srcs for a line-by-line URL list, or Copy as CSV to export the full table.
Frequently Asked Questions
Why should I audit images in HTML?
Images are one of the most commonly neglected elements in HTML quality checks. Missing or poorly written alt attributes hurt screen reader users and reduce the SEO value of your images in Google Image Search. Undefined width and height attributes cause layout shift (CLS), which is a Core Web Vital that directly affects search ranking. Running an image audit before publishing — or before migrating a site — lets you catch these issues in bulk rather than discovering them one by one in production.
What does missing alt text mean for SEO and accessibility?
Alt text serves two distinct purposes. For accessibility, it provides a text description of the image to users relying on screen readers or who have images disabled. Web Content Accessibility Guidelines (WCAG) require meaningful alt text on informative images and an empty alt="" on decorative ones. For SEO, alt text is how Google understands what an image depicts — without it, the image contributes little to keyword relevance and won't rank well in image search. An image with alt="" is intentionally treated as decorative and won't trigger an SEO flag; an image with no alt attribute at all is the real problem.
How do I bulk-fix missing alt attributes?
Export the results as a CSV, then open it in a spreadsheet. Add a column for your corrected alt values. Once you have them, you can use a find-and-replace workflow in your code editor: search for each src URL and add the corresponding alt attribute. For CMS-managed content, look for a bulk image editor in your CMS admin or write a migration script that reads your CSV and patches the relevant database records. The exported CSV gives you the structured inventory you need to track progress across a large site.
Does this detect CSS background images?
No. This tool only extracts <img> elements in the HTML source. CSS background images set via background-image: url(...) in stylesheets or inline styles are not captured, because they are not <img> tags and do not carry alt text by design. Background images should be decorative — if an image conveys meaningful content, it belongs in an <img> tag with a proper alt attribute, not in CSS.
