Auto OG Images – Open Graph & Social Image Generator by html2img

Links shared without an image get scrolled past. This plugin gives every post and page its own share image, generated from the post title, author and featured image the moment you publish. No design work per post, no image editor, no template plugin to fight with.

Rendering happens through the HTML to Image API, which draws each card in a real Chrome browser. Real browser rendering means proper fonts, emoji in titles and photographic featured images all come out right.

Full documentation is at html2img.com/integrations/wordpress.

How it works

1. Connect your HTML to Image account. New accounts get 50 free credits and each generated image costs one credit.
2. Choose which post types get images and pick one of five bundled designs. Set your accent colour and logo.
3. Publish. The image is generated in the background, saved into your media library and served in your og:image and twitter:image tags.

The plugin is careful with your credits. An image is only regenerated when something it shows has changed: the title, the excerpt, the author, the featured image or the design itself. Saving a post without changing any of those costs nothing. When you change the design, nothing re-renders until you ask: the Tools screen shows how many images are out of date and what a full regeneration will cost before it starts.

Features

• Five bundled designs: Classic, Split, Photo, Editorial and Minimal. All take an accent colour, an optional logo and show or hide the author and site name.
• Free browser preview on the settings screen, so trying designs costs nothing.
• Works with Yoast SEO, Rank Math, All in One SEO and SEOPress through their own filters, so tags are never output twice. With no SEO plugin, the plugin outputs the tags itself.
• A social image chosen by hand in your SEO plugin is respected by default. The generated image fills the gap on every post that has none.
• Gutenberg sidebar panel and classic editor metabox with the current image, a regenerate button and a per post off switch.
• Regenerate from the posts list, one at a time or as a bulk action, or everything at once from the Tools screen with a cost estimate up front, progress, resume and a clean stop if credits run out.
• Images live in your media library by default, so they keep working whatever happens to your account. They are hidden from the media grid unless you want them shown.
• A custom HTML template option with documented placeholders, for developers who want full control.
• Filters and actions for the variable payload, the generate decision, the render arguments and post generation. See the developer documentation on GitHub.

Credits and the free plan

HTML to Image accounts start with 50 free credits, a one time allowance rather than a monthly one. One credit is one generated image. Paid plans start at $9 per month for 1,000 credits.

Renders made on the free plan are kept on the HTML to Image CDN for 7 days. This plugin saves each image into your media library, so your share images keep working even after the CDN copies expire. Paid plan renders are kept permanently, and upgrading makes every earlier render permanent too.

The plugin shows your remaining balance on its settings screen, warns you when it runs low and pauses cleanly when it runs out. Your existing images are never touched by a failed render.

What this plugin is not

It does not edit your theme, slow your public pages or add JavaScript to the front end. It outputs a handful of meta tags and everything else happens in the admin. If you deactivate it, your existing images stay in the media library.

External services

This plugin sends data to the HTML to Image API at app.html2img.com to generate images. It sends the post title, the post excerpt, the author display name, the site name and tagline, the post date, the featured image (inlined or by URL) and the design HTML including your logo and colour settings. Data is sent when a post is published or updated with relevant changes, when you press regenerate, during bulk regeneration and when you request a test render from the settings screen. Your API key is sent with each request to authenticate it.

The generated images are stored on the HTML to Image CDN and downloaded into your media library. No visitor data is ever sent, and nothing is sent from your site’s public pages.
