Open Graph images from a URL
Imgen creates the preview image that social networks and chat apps show when someone shares a page. Instead of designing, exporting, uploading, and storing a separate image for every article, you can build one URL with the page title, a background image, and an optional logo.
Use that generated URL in your og:image or twitter:image meta tag, or store it in your CMS as the social preview image. The image can be hotlinked directly from your pages.
1. Add a background
Pass a public image URL in the bg parameter. Use article art, a branded template, or a reusable default background for your blog.
2. Add the title
Pass the headline in the txt parameter. Imgen renders the text into a social-cover layout suitable for link previews.
3. Add a logo
Pass a logo image URL in the logo parameter to keep generated images recognizable in social feeds.
Hotlinkable image URLs for blogs and CMS previews
Imgen is useful when your site has hundreds or thousands of pages that need consistent Open Graph images. A CMS, static-site generator, or custom backend can build the image URL while rendering the page, using the same title and artwork already stored for the post.
Because the output is a URL, there is no file upload workflow to maintain. You can generate a fresh social preview image whenever the title, background, or logo changes, and paste the result into the page metadata immediately.

- bg
- The background image URL. Encode it before adding it to the query string.

About
- What is this
- This tool autogenerates "open graph" social media cover images with a simple GET request to our API. The resulting URL can be later hotlinked in your articles and posts, no need to save/upload the image. The most popular use-case is to embed the URL-generating code right into your CMS backend.
- Free forever
- We will never monetise this.
- Why even build it
- The existing free alternatives are sometimes buggy, the existing paid alternatives are sometimes ridiculously overpriced.
- Tech stack
- The backend is on ASP.NET Core (because it's fast), uses "Skia" for image manipulation (portable C++ library from Google), and works behind Cloudflare's caching CDN.
