Square Thumbnails

Square Thumbnails PRO will be available soon. All features currently in the free version will remain free and unrestricted.

Square Thumbnails transforms your images into perfect square thumbnails without cropping or distorting them. Instead of cutting off important parts of your images, the plugin fits them entirely within a square frame, similar to CSS background-size: contain. Ideal for WooCommerce shops, portfolios, and image galleries where consistency is essential, but you don’t want to lose parts of your images.

Key Features

• No Cropping: Preserves the entire image within a square frame
• Background Options: Transparent or colored backgrounds (custom or auto-detected)
• Format Support: Works with JPEG, PNG, GIF, WebP, AVIF, and BMP
• Quality Control: Adjustable JPEG quality settings (60-100%)
• Selective Processing: Choose which image sizes to convert to squares
• Small Image Handling: Special options for handling small images
• Individual image regeneration: Easily regenerate only one image from image details page
• Bulk Regeneration Option (included): Easily update existing thumbnails with progress tracking. No need to use other plugins to regenerate images
• WooCommerce Ready: Perfect for product galleries with uniform thumbnails
• Newsletter Integration: Add newsletter subscription forms with Mailchimp integration

Perfect for online stores where you want all products to have uniform square thumbnails while maintaining complete product visibility.

I’ve successfully implemented the two requested features for Square Thumbnails version 2.3.0:

1. JPEG Quality Control

• Added a new setting to control JPEG compression quality (60-100%, default 90%)
• This allows users to balance between image quality and file size
• The setting is applied when saving JPEG images after processing

1. Selective Size Processing

• Added the ability to choose which image sizes should be processed as square thumbnails
• Displays all registered image sizes with their dimensions
• WooCommerce sizes are highlighted in purple and shown first for easy identification
• Added quick selector buttons:
  • Select All
  • Select None
  • Select WooCommerce Only
  • Select WordPress Default

  If no sizes are selected, all sizes will be processed (backward compatible)

  Additional improvements:

  Enhanced the settings page layout with two new sections

  Created comprehensive changelog and documentation

  The plugin now offers much more granular control over thumbnail generation, which is especially useful for
  WooCommerce stores that want to optimize performance by only processing the sizes they actually use.
