Free alt-text checker

Give your product image description a quick writing check before publishing. No signup. Everything runs in your browser.

Check a description

0 characters. This tool checks writing patterns, not the image itself. Your text is not uploaded or saved.

This is a rule-based writing aid. It cannot verify visual accuracy, screen-reader experience, accessibility compliance, or search performance.

What makes useful product alt text?

Describe the image’s purpose in context. For a product photo, that often means the product, visible color, distinguishing details, and the view shown. Avoid repeating a list of search terms.

Practical workflows

Before and after

Instead of “IMG_2048.jpg”, try “Round oak dining table with four tapered legs, top view.” Only use details that are actually visible.
