"I am so impressed with this plugin. I never bother writing plugin reviews but this plugin blew my mind. Definitely upgrade." - @buttonmode ★★★★★ "I downloaded the free version and after 3 minutes I bought the PRO version. The plugin is EXCELLENT! For a year I didn't know what to do with WooCommerce photos, because we have 30,000 imported products with different photos." - @prokurent ★★★★★ "I recommended this to a dev friend the day after I used it, he used it as well. (We both ended up getting the Pro version to leave it on, customers don't care to crop their images on their own tbh)." - @jpontinen ★★★★★ "[••]The time saving benefits are enormous and the plugin support is A+. They have a chat that helps you solve any issues immediately." - @chickwithbobUsage

常见问题:
My product images are showing in different sizes, will the plugin make them uniform without cropping?
Yes, that's exactly what the plugin does. It makes all your product images the same size by adding a background color around them instead of cropping. Your products stay fully visible and your store looks professional.
Does the plugin automatically resize images on upload?
Yes. Once activated, every new product image you upload is automatically resized to match your store's image sizes. No extra steps needed.
Do I need to configure anything before the plugin starts working?
No configuration needed. The plugin works immediately after activation with smart defaults. However, you can customize the background color, enable whitespace trimming, or choose which image sizes to process by going to WooCommerce > Smart Image Resize > Settings.
How do I resize already-uploaded product images?
Go to WooCommerce > Smart Image Resize > Bulk Regenerate and click Start Processing. The tool will resize all your existing product images automatically. Note: If old images still appear after processing, clear your site's cache (caching plugin, CDN, and browser cache).
My images look blurry or low quality after resizing. What should I do?
There are two common causes:
- Compression is too high — Go to WooCommerce > Smart Image Resize > Settings, open the Optimization section, and lower the compression level. A lower value means better quality.
- The original image is too small — When an image is smaller than the target size, the plugin stretches it to fit, which causes blurriness. You can turn on Disable Upscaling under Settings > Advanced settings to prevent stretching — the image will be left at its original size and padding will be added around it instead. Alternatively, upload a larger version of the image.
The plugin processed my images but they still look different on the frontend. Why?
This is almost always a caching issue. After processing, clear your site's cache (caching plugin, CDN, or browser cache) and reload the page. The updated images should appear correctly.
Images aren't being resized on upload. What could be wrong?
A few things to check:
- Make sure Image Uniformity is enabled in Settings.
- Make sure the PHP
fileinfoextension is enabled — your hosting provider can confirm this. - If images still aren't processing, try switching the image processor under WooCommerce > Smart Image Resize > Help > Image Processing. Switching between the available options can resolve compatibility issues on some servers.
What background color is used by default, and how do I change it?
White is the default background color. To change it, go to WooCommerce > Smart Image Resize > Settings and select a color under Background Color. Leave it empty to keep transparency for PNG images.
The bulk tool stopped partway through. What happened?
Your server ran out of memory while processing large images. Refresh the page and click Start Processing again — the tool automatically resumes where it stopped. If this keeps happening, contact your hosting provider to increase the server's memory limit.
Can I undo changes?
Yes. Turn off Image Uniformity in Settings, then go to WooCommerce > Smart Image Resize > Bulk Regenerate and run the tool. This regenerates all thumbnails using the original WordPress sizing.
Which image sizes does the plugin process?
By default, the plugin processes all standard WooCommerce image sizes (thumbnail, medium, woocommerce_thumbnail, woocommerce_single, etc.). You can customize which sizes to include or exclude under Settings > Advanced settings > Image Sizes.
I need to change the default WooCommerce sizes, is it possible?
Yes. Go to WooCommerce > Smart Image Resize > Settings to customize the default WooCommerce image dimensions.
Will this affect non-product images?
No. By default, the plugin only processes product images. You can enable category images in the plugin settings if needed.
Can I use the plugin to resize non-product images as well?
How can I know which images have been resized?
In your Media Library, use the filter dropdown and select "Smart Resize: Processed" to view only images that have been resized by the plugin.
I get an error when I upload an image
Make sure the PHP fileinfo extension is enabled on your server. Contact your hosting provider if you need help enabling it.
Is the plugin compatible with Dokan Multivendor?
Yes. Vendors can upload product images and the plugin will automatically resize them.
Is the plugin compatible with WooCommerce HPOS?
Yes. The plugin is fully compatible with WooCommerce High-Performance Order Storage (HPOS).
Is the plugin compatible with WP CLI?
Yes. Use the command wp media regenerate to bulk resize your existing images via command line.
