FAQ
Gut zu wissen
How do I use Image Alt Text Checker?
1. Paste page HTML: Use page source or copied rendered HTML. Nothing is fetched or executed. 2. Review each image: Check img, image inputs and image-map areas for missing, empty and filename-like alt text. 3. Fix in context: Describe informative images and review whether an empty alt is appropriate for decorative images.
Is empty alt always an error?
No. Decorative images often need alt="". The tool marks empty alt for review, especially on linked images and controls; it cannot decide whether an image is decorative.
Does it prove accessibility or SEO quality?
No. Presence is not accuracy. Review image purpose, nearby text and accessible naming manually. CSS backgrounds, SVG and JavaScript-generated images absent from your input are outside this check.
Are images loaded?
No. HTML is parsed in an inert template. The report shows source strings without requesting images or executing scripts.
