Alt Text Generator

Draft SEO- and accessibility-friendly alt text from a filename and a short description — no image upload needed.

Generate alt text with AI

Paste a public image URL and, optionally, where it's used. Draftbase's server fetches the image and a vision model writes the alt text — the image isn't stored, just processed for this one request.

How it works

This is a text heuristic, not computer vision: it cleans up the filename (splitting team-photo-office.jpg into words) and combines it with what you describe and where the image is used, then flags any suggestion over the ~125-character screen-reader guideline. Nothing is uploaded — see how the same field is stored for real in a media library.

Store alt text once, reuse it everywhere

Draftbase's media library stores alt text per asset, so every entry that references the same image reuses one description instead of retyping it per page.

Frequently asked questions

What makes good alt text?

A short, specific description of what the image shows and why it’s there — not a keyword list, not "image of...", and under roughly 125 characters so screen readers don’t truncate it awkwardly.

Does this tool actually look at my image?

No — it assembles suggestions from the filename and the description you type, it doesn’t analyze pixels. Use it to draft faster, then adjust the wording to match what the image actually shows.

Does alt text affect SEO?

Indirectly. Search engines use alt text to understand image content for image search, and it’s required for accessibility compliance (WCAG), but it won’t move a page’s ranking on its own.
