OG Herro

OG Herro generates Open Graph images and matching meta tags from any URL. Paste a link and AI extracts page details, then produces a 1200x630 PNG plus tags for Facebook, X, LinkedIn and Pinterest. Free accounts get 5 images; paid plans use credits that recharge each period and never expire.

OG Herro turns a single URL into a finished Open Graph image and the meta tags that go with it. Paste a link, and the service fetches the page, runs the content through an AI model to pull out the title, author and other key details, then generates a visual that reflects what the page is about. The output is a 1200x630 PNG at the standard 1.91:1 ratio, so it drops into social previews without cropping on Facebook, X, LinkedIn or Pinterest. Because the tool also writes the accompanying tags, including the Twitter Card markup that X reads, the job of preparing a link for sharing is handled in one pass rather than three or four separate steps. The workflow suits publishers, marketing teams and developers who ship a lot of URLs and do not want a designer in the loop for every article, landing page or changelog entry. Each generation returns two assets: a composed version carrying the title and author text, and a raw background version with no text, which is useful when a template or CMS needs to place the copy itself. The stated use case covers anything with a public page, including the sample links the site highlights from large media and infrastructure companies. Against hand-built templates in Figma or Canva, the trade-off is control for speed. OG Herro does not present itself as a design canvas, and the value is in automating a repetitive task across many pages. Teams that already maintain a strict brand system may find the AI-selected visuals require review before publishing. The REST API is the other half of the pitch: image generation can be called programmatically for any URL, which makes it viable as a build step or a hook in a CMS pipeline rather than only a manual web tool. Ownership is stated plainly: generated images belong to the user and can be used commercially, including in marketing material. Output arrives in PNG, which keeps transparency available. The site points users to the official Facebook, X, LinkedIn and Pinterest debuggers for checking how a link renders after the tags go live, and those tools also force a re-fetch of cached metadata.
