FAQ
Is it free?
Yes, all features are completely free.
What counts as 'too long' alt text?
Alt text over 125 characters is flagged as too long. Most screen readers truncate alt text around this length, and search engines may not fully index longer alt text.
Why is empty alt text sometimes OK?
An empty alt attribute (alt="") is intentional for decorative images. It tells screen readers to skip the image. The tool flags these so you can verify the decision was intentional.
Is my data sent anywhere?
No. All processing happens in your browser. No image data or page content is ever sent to any server.
