How it works
Paste a page or describe an image
A URL gives alt text for the images on that page. A description gives three versions for one image.

English (United States) is selected for you - alt text can be written in 30 languages.
Copy and paste
Add it to your pin's alt text field on Pinterest, or to the image on your website.
Why alt text matters on Pinterest
Alt text describes an image for people who use screen readers. Pinterest reads it too, so a clear description that fits the pin's topic helps it understand what the pin shows. Pinterest allows up to 500 characters - one or two clear sentences are enough.
How to write good alt text
- Describe what is shown: the subject, the setting, any text on the image.
- Stay honest: no words that are not in the picture just to rank.
- Keyword only if it fits: if the image shows "easy weeknight dinners", say so.
Check your whole pin with the pin preview & SEO checker, and see which images on your page are missing alt text with the Rich Pins validator.
Frequently asked questions
What is alt text on Pinterest?
A short description of the pin image for people who cannot see it. Pinterest reads it too, to understand what the image shows.
How long can Pinterest alt text be?
Up to 500 characters. One or two clear sentences usually say everything.
Can the tool see my images?
No - it writes from what it is told: the image's current description and file name on your page, and the page text. That is why it never invents details.

Yes. You get 3 free uses a day, with no signup.
