Imgen by Jitbit is a free API that generates Open Graph and Twitter preview images from a title, background, and logo URL.
Imgen is a free API from Jitbit Software that generates social preview images used in Open Graph and Twitter Card meta tags. Instead of designing and uploading a static preview image for every page, sites can generate one dynamically via a URL.
The service accepts a background image, a title, and an optional logo as URL parameters and renders a finished, hotlinkable image on demand, which can be referenced directly in a page's meta tags.
Imgen removes the need for an upload workflow: images are generated purely from URL parameters (bg for background, txt for title text, and logo for an optional logo image), with text automatically formatted to fit standard social preview layouts.
Because output is a simple hotlinkable URL, it can be embedded directly into a CMS or backend system to automatically generate consistent social images for every new piece of content, without manual design work per page.
Imgen is completely free to use, with Jitbit stating on the site that it will never monetize the service. There are no paid tiers, usage limits, or account requirements described.
The service runs on ASP.NET Core with Google's Skia image rendering library and is cached through Cloudflare's CDN, keeping response times fast for high-volume use.
