Description
ThumbAPI for WordPress turns your post title into a production-ready featured image with a single click. No template design, no image editing, no extra steps in your publishing flow.
The plugin adds a panel to the post editor (both the block editor and the classic editor). When you click Generate featured image, the current post title is sent to your ThumbAPI account, the returned image is uploaded to the Media Library, and it is set as the post’s featured image automatically.
Features
- One-click featured image generation from the post title
- Block editor sidebar panel and classic editor meta-box integration
- Five output formats: Blog post (1200×630), YouTube (1280×720), Instagram (1080×1080), X (1200×675), LinkedIn (1200×627)
- Three image styles: faceless, with personal photo, with logo
- Generated images go through the standard WordPress Media Library — full thumbnail sizes are generated automatically
- No bundled scripts or styles loaded outside the post editor and the plugin’s own settings page
What you need
- A ThumbAPI account and an API key from app.thumbapi.dev
- For « With image » or « With logo » styles, upload your personal photo or logo once in your ThumbAPI dashboard
External services
This plugin sends data to ThumbAPI (https://api.thumbapi.dev), which is a paid third-party service operated by ThumbAPI. When you click Generate featured image, the plugin sends the post title, your selected format, and your selected image style to the ThumbAPI POST /v1/generate endpoint, authenticated with the API key you saved in the plugin settings. ThumbAPI returns a generated image which the plugin then stores in your WordPress Media Library.
