What is the maximum image file size on Pinterest? (Pinterest ad spec)
These are Pinterest's published ad specs, from its "Review ad specs" page. Pinterest says each of these ad formats "can be used in paid ad campaigns or to generate organic impressions", but it doesn't say the same limits apply to every organic Pin.
Pinterest allows images up to 20 MB on desktop and 32 MB in the app. Verified 2026-10-16 from the official Pinterest page.
