What is Pinterest alt text?

Alt text (alternative text) is a short description of an image. On Pinterest, it helps visually impaired users understand your pin, and it tells Pinterest's algorithm what the image is about — improving your pin's discoverability in search.

Why does Pinterest alt text matter for SEO?

Pinterest uses alt text as a ranking signal in its visual search engine. Pins with descriptive, keyword-rich alt text are more likely to appear in search results and related pin suggestions. It's one of the easiest SEO wins on the platform.

How long should Pinterest alt text be?

Pinterest allows up to 500 characters for alt text. The ideal range is 100-500 characters — long enough to be descriptive and include keywords, but concise enough to be useful for screen readers.

How is this different from a pin description?

The pin description is the visible caption below your pin. Alt text is a hidden accessibility field that Pinterest also uses for search indexing. Both are important, but alt text specifically describes what's in the image itself.

Does this tool store my images?

No. Your image is sent directly to the AI for analysis and is not stored on our servers. The image data stays in your browser and is only transmitted for the generation request.

What image formats are supported?

JPEG, PNG, and WebP images up to 4 MB. These are the most common formats used for Pinterest pins.
