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.

API parameters

bg
The background image URL. Encode it before adding it to the query string.
txt
The title or short text to render on the generated social image.
logo
An optional logo image URL for the lower corner of the preview image.

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.
