Accessibility
ALTtext isn't only a tool for people adding descriptions to images. It's a tool for you — if you're blind or have low vision, you can point ALTtext at any image and get a clear description read aloud, on demand, without waiting for whoever posted it to write one.
What ALTtext does for you
When you meet an image with no description, a screen reader usually says just "image" or reads out a meaningless file name, and the picture simply disappears from the page. ALTtext fills that gap: it looks at the image and writes an accurate, plain-English description in a few seconds. The description is both shown on screen and spoken, and your screen reader moves straight to it so you can read it word by word, copy it, or move on.
It's free, needs no account, and there's nothing to install to use it on the web.
How to use it with a screen reader
On this website
The generator on the home page takes an image and returns a description you can read and copy.
- Find the "Upload an image" button and choose a photo from your device, or paste an image you've copied.
- Activate Generate. The status is announced while it works.
- When it's done, the description appears in a text area that your screen reader will read. Use the Copy button to put it on your clipboard.
In your browser, on any page
The browser extension works on images anywhere — social feeds, news sites, anywhere an image sits without a description.
- Move to the image and open its context menu — with most screen readers that's the Applications key, or Shift + F10.
- Choose "Generate ALT text with ALTtext."
- The result opens as a dialog that takes focus and reads the description aloud immediately. Copy copies it; Dismiss (or Escape) closes it and returns you to where you were.
A note on how it reads: results are delivered as an assertive announcement and the focus is moved onto the description text, so you hear it through your own screen-reader voice — we don't talk over you with a second voice.
What we support
- Screen readers — VoiceOver, NVDA, and JAWS. Generated results are announced and receive focus so they're read without hunting for them.
- Keyboard only — every action can be reached and triggered from the keyboard; nothing needs a mouse.
- WCAG 2.2 — we build to the Web Content Accessibility Guidelines, starting with text alternatives (Success Criterion 1.1.1) — the whole reason ALTtext exists.
- Your voice, not ours — descriptions are surfaced to your screen reader rather than spoken by a competing synthetic voice.
- No barriers to entry — the core generator is free, with no account and nothing to install.
Accessibility is never "done," and some corners will be rougher than others. If something gets in your way, we want to hear about it — the form below comes straight to us.
