Plan and check alt texts: the alt text manifest
Enter your list of images, one by one or as a CSV with file name and context. For each image a decision tree walks through the right choice: if the image is purely decorative, the alt attribute stays empty. If it carries content, you need a statement. If it is a link, the alt text describes the destination, not the picture.
The quality check flags texts longer than 125 characters, filler phrases like image of, and alt texts that merely repeat the file name. At the end you export a CSV with file name, alt text, decision and reason, or a list of finished HTML snippets ready to paste. Everything stays local in the browser.
Frequently asked questions
When should the alt text stay empty?
For purely decorative images that carry no content: background patterns, divider lines, purely stylistic elements. The empty alt attribute tells screen readers they may skip the image. A missing attribute is something different from an empty one.
How long may an alt text be?
Around 125 characters is the common guideline, because many screen readers cut off longer texts. The check marks longer texts, then you decide whether to shorten or move the description into the surrounding copy.
What is the CSV in the manifest for?
It is your working list for implementation: file name, finished alt text, decision and reason in one file. A developer can build the texts in without follow-up questions, and the reason documents why an image stays decorative.
