Frequently asked questions

Is the alt-text generator free?

Yes — free and no sign-up. Upload an image and get alt text, a filename, a caption and keywords.

Why is alt text kept to 125 characters?

Screen readers work best with concise descriptions, and around 125 characters is the widely-followed accessibility guideline. The tool keeps alt text within that limit while still describing the essentials.

Does it describe things that aren't in the image?

No. It describes only what's visibly in the picture and never adds keywords or claims that aren't there — accurate alt text is what actually helps both accessibility and SEO.

How does the use-case change the output?

It retunes the caption tone, the keyword emphasis and the filename style to fit the context — an ecommerce product, a blog image and a social post each get a treatment that suits them, while the alt text stays factual.
