General
SleekPixel generates images from a design rather than from an upload: a social sharing card, a featured image, a quote card. You lay the image out once in a visual editor, bind its text and pictures to WordPress data such as the post title or the author’s avatar, and Pixel renders one image per post on the server with ImageMagick.
Where it lives
Pixel runs in two forms with the same screens:
- In the suite, Pixel is a product in the workspace sidebar. It opens on its image library and lists Images, Settings and License beneath it.
- As the standalone SleekPixel plugin, it has its own Pixel entry under the SleekWP menu in the WordPress admin, which shows only Pixel’s navigation.
Both need the Imagick PHP extension. Without it Pixel registers neither its front-end output nor its REST operations, so its screens cannot load; see Troubleshooting.
What you can do
- Design images on a canvas of any size with text, image and section elements, in the image editor.
- Start from a template. The editor’s Templates view offers 259 starter designs in eight formats: Open Graph, Twitter Card, Featured Image, Instagram Post, Instagram Story, Facebook Cover, YouTube Thumbnail and Pinterest Pin.
- Fill an image from WordPress data with dynamic data about the post, its author, the site, the archive and the query, or with your own entries.
- Choose where an image is used in its Conditions view: Open Graph and Twitter Card tags, the featured image, or a panel in the block editor sidebar, each limited by rules such as the post type.
- Render it yourself with the PHP functions or the shortcode.
- Use your own fonts: upload font files or connect Google Fonts.
- Work with the assistant, which can read and edit the open design; see Assistant.
- Script it with the
wp sleek pixelcommands. - Keep designs as files under
sleek/pixel/in the active theme with Agent Sync, to version them or let a coding agent edit them.
How an image is produced
- You save a design. Pixel stores it as an image record with its elements, canvas settings and conditions.
- A page is requested. When a design’s conditions match that page, Pixel renders the design for the current post, or reuses the file it rendered before, and writes it into the page.
- Rendered files are cached under
wp-content/uploads/sleek-pixel/images. A file is rendered again when the design, the post, the data passed to it, the language or the plugin version changes.
Options decides the file format and whether a missing file is rendered during a signed-in user’s request or in the background; for visitors it always renders in the background.
