Frequently Asked Questions
Why is alt text important?
Alt text describes images for screen readers, improving accessibility for visually impaired users and helping SEO by providing context to search engines.
Does this tool use any APIs?
No, it's completely free and self-contained using PHP cURL for fetching and regex for parsing – no external services or sign-ups required.
What if no alt text is needed for an image?
Decorative images should use empty alt="" attributes. Our tool flags missing ones, but you can manually review for decorative purposes.
How accurate is the scan?
It uses reliable HTML parsing to detect <img> tags. For complex JS-loaded images, a manual check may be needed.
