Image Alt Text Scraper

Audit image alt text on any page

Alt text describes an image for people who use screen readers and for search engines, which cannot see pictures. It is one of the simplest accessibility wins and helps images rank in Google Images. This tool lists every image on a page with its alt text, so you can spot gaps in seconds instead of opening the source code.

What is reported for each image

• Alt text status: missing, empty (decorative) or present, with warnings for alt text that is very long, repeats the file name or starts with "image of".
• Image address: from src, srcset, picture sources or lazy-load attributes, resolved to a full URL with a thumbnail.
• Width and height attributes: missing dimensions cause layout shift while the page loads.
• Loading hints: loading="lazy", decoding and fetchpriority, so you can check that the main image is not lazy loaded by mistake.

Writing better alt text

Describe the content and the purpose of the image in a short sentence. A product photo might read "Blue canvas backpack with brown leather straps", while a chart needs the key figure it shows. Logos that link home can use the brand name. Icons next to text that already says the same thing, and purely decorative shapes, should have an empty alt so screen readers skip them.

Filter the list to missing alt, fix those first, then review empty ones to confirm they are truly decorative. Download the CSV to hand the list to whoever edits the content, or to compare before and after a fix.
