Pinterest Alt Text Generator

Pinterest alt text is a short description of what a Pin's image shows, read aloud by screen readers. Pinterest allows up to 500 characters. This generator turns your notes on the subject, the setting and any words on the image into three alt text options. It formats what you describe; it does not look at the image.

That is on purpose. Nothing is uploaded, so your image stays private, and the alt text says only what you told it, so it cannot invent a detail that is not in the photo. You are the one who can see the image, which makes your notes the best source.

Pinterest's help center says alt text makes your Pin more accessible to people who rely on screen readers, and that it currently works for standard and video Pins. Write it for that person first: what would they miss if they could not see the image?

The tool builds up to three options from your notes. The short option names the subject and the setting, for people who want to move on quickly. The full option adds your details. The text-first option leads with the words on the image, which suits text-heavy Pins such as recipe titles, checklists and quotes.

It also checks your notes for common mistakes: openers like "image of", hashtags, links, calls to action, styled Unicode letters and the same word repeated again and again. It does not look at your image, recognize people or guess what is in the photo. If you ever use an AI that describes images for you, compare its result with the picture before you publish, because it can get details wrong.

Pinterest's help page on alt text presents it as an accessibility feature and does not say it affects distribution. Pinterest does say that descriptions are used by its algorithm to judge relevance for delivery (source: Review Pin specs, Pinterest Help Center, checked October 2026). So put your search keywords in the title and description, and use alt text to describe the image honestly. If a keyword truly names what is in the photo, it belongs there once.

If writing titles, descriptions and alt text for every Pin sounds like a lot, the PinBoostr AI pin generator drafts all three for Pins made from your own posts, with alt text kept under 500 characters. You review and edit each Pin, and nothing publishes until you approve it.

For the rest of a Pin's text, the free pin title and description generator writes keyword-ready ideas, the pin size checker makes sure the image fits the feed, and our Pinterest SEO guide shows how titles, descriptions and boards work together.

On the web: create a Pin, upload the image, add the title and description, open More options and paste your text into the Alt text field, then publish. To change it later, open the Pin, click the three-dot menu, choose Edit Pin and update the alt text (source: Add alternative text to your Pins, Pinterest Help Center, checked October 2026).

In the app: tap the plus icon, choose Pin, pick the image, tap Next, then open Advanced settings to add alt text. Pinterest notes that business accounts should edit alt text on the web, while personal accounts can use the app.
