About this plugin
Crates Product Image Processor saves you from manually opening every product photo in Photoshop before it goes live. As soon as an image is uploaded directly on a WooCommerce Product edit screen, the plugin steps in — before WordPress even generates its thumbnail sizes — and automatically standardizes it to your store’s exact specifications.
What it does to each image:
- Trims the background. Detects and removes existing whitespace, margins, or near-white backgrounds around the product using a configurable tolerance (“fuzz”), so a raw, ungrouped product photo is reduced to just the product itself.
- Removes the leftover edge halo — without eating into the product. A plain trim rarely gets a perfectly clean cut, and a faint sliver of the old backdrop usually survives at the edges. The plugin clears that residual halo starting from the image corners, so it only removes background actually connected to the edge — white packaging, labels, garments and highlights inside the product are untouched. It uses its own conservative tolerance, separate from the trim tolerance, and automatically backs that tolerance off if it detects the removal spreading into the product.
- Corrects rotation automatically. Reads EXIF orientation data so photos taken on a phone or camera are processed right-side up, without you having to rotate them first.
- Normalizes colour. Supplier photography often arrives in CMYK. Images are converted to sRGB before compositing, so colours don’t shift when the product lands on the canvas.
- Places the product on a branded canvas. Centers the trimmed product on a canvas of your exact chosen width and height, with your specified background color and a consistent padding offset around every product — so your whole catalog has matching proportions and framing.
- Handles small images sensibly. By default, a product photo smaller than your canvas’s usable area is kept at its native resolution and simply centered, to avoid pixelation. If you’d rather have every image stretched to fully fill the canvas instead, you can turn that on in settings.
- Keeps your original safe. Before overwriting the uploaded file, the plugin saves an untouched copy of the original in a dedicated folder in your uploads directory — so a setting you’re not happy with never means re-uploading from scratch.
Bulk-process existing images, on your terms.
New uploads are processed automatically, but what about the products you added before installing this plugin? Under Media → Bulk Process Images, you can open the familiar WordPress Media Library picker, hand-select exactly the images you want processed, and run them through the same canvas pipeline — with a progress bar and a per-image success/failure log.
Nothing is selected by default and nothing runs automatically: since many sites reuse the same Media Library for blog posts, sliders, and other design elements that should never be touched, this tool only ever processes images you explicitly pick.
Where it applies (and where it doesn’t):
This only ever runs on images uploaded directly through a WooCommerce Product edit screen (including the product gallery uploader), and on images the WooCommerce product CSV importer downloads from external URLs. Uploads to regular posts, pages, sliders, or any other part of your site are left completely untouched.
CSV product imports.
When a row in a WooCommerce product CSV lists its images as full URLs on another site, WooCommerce downloads each one into your Media Library during the import. Each downloaded image goes through the same canvas processing before its thumbnails are made, so an imported catalogue matches products added by hand. Images the CSV refers to that are already in your Media Library (an uploads URL, a bare filename, or a URL an earlier import already downloaded) are reused as they are and not processed again.
This can be switched off under Settings → Product Image Processor.
Requirements:
- The PHP Imagick extension must be installed and enabled on your server. If it isn’t available, the plugin simply leaves uploads unprocessed rather than causing an error.
- Supports JPEG, PNG and WebP images. WebP needs an ImageMagick build with WebP support, which most hosts have. Animated images are left as they are.
- WooCommerce must be active, since processing is scoped to the product post type.
