Rapls PDF Image Creator is a WordPress plugin designed to automatically generate thumbnail images from PDF files uploaded to the WordPress Media Library. When a PDF is uploaded, the plugin uses ImageMagick (with the Imagick PHP extension) to convert the first page of the PDF into an image, which is then registered as the featured image for that PDF. This process is fully automated and requires no manual intervention. The generated thumbnails replace the default generic PDF icon in the Media Library, providing a visual preview of each document.
The plugin supports multiple output formats for thumbnails, including JPEG, PNG, and WebP, and allows users to select the preferred format based on compatibility or file size requirements. It also generates images in all sizes registered with WordPress, such as full size, large, medium, thumbnail, and any custom sizes added by the theme, supporting responsive image features like srcset. Rapls PDF Image Creator is compatible with both the Classic and Block Editors, enabling users to insert PDFs into posts with thumbnail images, title links, or custom HTML templates. Additionally, the plugin integrates with the editor to provide various insertion options, including image-only links, title links, or fully customized HTML output using placeholders.
For sites with existing PDF files, the plugin offers a bulk generation feature that processes all current PDFs in the Media Library, creating thumbnails for each. It is also equipped to handle PDFs in CMYK color space and PDF/X-1:2001 format, which are commonly used for print submissions, and performs automatic color space conversion to avoid issues like black thumbnails. Users can configure settings such as maximum image dimensions, JPEG/WebP quality, background color, and which PDF page to use for the thumbnail. There are also options to hide thumbnails in the Media Library, replace the default PDF icon, and choose whether to keep or delete generated images upon plugin uninstallation.
