Consistent thumbnails,
no cropping.
Thumb Generator produces square WooCommerce product thumbnails with padding around each image. Every product shows in full regardless of its original aspect ratio. Perfect for catalogs with mixed image sizes.
Consistent product images, always
Zero cropping
Every image is scaled to fit inside the target square. The original product stays fully visible. Padding fills the remaining space.
Configurable settings
Output size (200–1200px), padding percentage (0–20%), background colour, JPEG quality, and overwrite existing flag.
Batch processing
Processes all published WooCommerce products including featured images and gallery images. A progress bar shows how many are done.
Incremental runs
With Overwrite existing off, the generator skips products already processed. Add new products, run again, and only new images are generated.
Original files untouched
Generated thumbnails replace the thumbnail-size files, not the original uploads. Source images remain at full resolution.
Works with any catalog size
From a dozen products to thousands. The generator resumes where it left off if processing is interrupted, so large catalogs are safe to run.
