Woocommerce store with thousands of existing products and more added daily. We have to source our product images from various suppliers and manufacturers, all whom save their images in different formats and sizes. Some of which have a lot of unnecessary white space which affects all of our product thumbnails. So some products look smaller than others on archive galleries. You can use the built in crop tool on woocommerce so they’re all 1:1 but it will obviously crop some of your images which looks horrendous. This tool with a click of a button processed all our images, removed all the unnecessary white space and resized them so now every single product image appears the same size. Preprocessing our images in photoshop would be an impossible task as we already have thousands of images and add more daily. This took 5 minutes to setup. Let the bulk gen run and walk away. Come back and it’s finished. I upgraded to the pro version which was on sale. Lifetime license for the cost of a one year subscription. Now not only do all the products appear uniform but are displayed in webp which Imagify wouldn’t do for thumbnails. ![](https://secure.gravatar.com/avatar/65bb553d6c5b1cb94b841e207bd3a4334abcea1ab09187c383d7c4eafc3a2e13? s=60&d=retro&r=g) ### 󠀁[Smart Image Resize IS SMART!](https://wordpress.org/support/topic/smart-image-resize-is-smart/)󠁿 [ejcalvarez](https://profiles.wordpress.org/ejcalvarez/) 2025 年 10 月 15 日 Smart Image Resize is very help and easy to use! ![](https://secure.gravatar.com/avatar/2d12e035a4c66e93e7e9c3256b7a257ee958ecb1b3be382475f14f37a035d873? s=60&d=retro&r=g) ### 󠀁[Only works halfway](https://wordpress.org/support/topic/only-works-halfway/)󠁿 [zettbee](https://profiles.wordpress.org/zettbee/) 2025 年 5 月 9 日 1 則留言 The plugin creates new images but does not change the original. Many of the current( premium) themes automatically change the uploaded images to .webp. Because these are so small, they use the original for zoom images, product thumbnails and lightbox. I manage 10+ webshops with different premium themes and see that the images created by the plugin are only used in the product gallery and product image. The thumbs, zoom, etc. are the unmodified original image. So if the original is also modified, the plugin works 100%, now it only works half. ![](https://secure.gravatar.com/avatar/762896ad3c9a952eaae8c800c181632ca0f9f27979a3ad1b8c4bf69f6a7d0443? s=60&d=retro&r=g) ### 󠀁[Does the trick](https://wordpress.org/support/topic/does-the-trick-119/)󠁿 [kosia](https://profiles.wordpress.org/kosia/) 2024 年 6 月 10 日 1 則留言 Easy to use, sorted out my image problems. ![](https://secure.gravatar.com/avatar/747d94491468911534482ddeddd06ad056a87468c74b1e4269e2d6e78803b54e? s=60&d=retro&r=g) ### 󠀁[Seems to work good](https://wordpress.org/support/topic/seems-to-work-good-7/)󠁿 [valterekholm](https://profiles.wordpress.org/valterekholm/) 2024 年 4 月 23 日 Since I have not used it much I can only give 4 ![](https://secure.gravatar.com/avatar/65bbdef07636ea37f7b8680e1e94dc12efa860608d87ab2422da74f200dc272b? s=60&d=retro&r=g) ### 󠀁[Very helpful plugin](https://wordpress.org/support/topic/very-helpful-plugin-453/)󠁿 [merchandcart](https://profiles.wordpress.org/merchandcart/) 2024 年 4 月 11 日 Very helpful plugin [ 閱讀全部 82 則使用者評論 ](https://wordpress.org/support/plugin/smart-image-resize/reviews/) ## 參與者及開發者 以下人員參與了開源軟體〈Smart Image Resize – Make WooCommerce Images the Same Size〉 的開發相關工作。 參與者 * [ Nabil Lemsieh ](https://profiles.wordpress.org/nlemsieh/) [將〈Smart Image Resize – Make WooCommerce Images the Same Size〉外掛本地化為台灣繁體中文版](https://translate.wordpress.org/projects/wp-plugins/smart-image-resize) ### 對開發相關資訊感興趣？ 任何人均可[瀏覽程式碼](https://plugins.trac.wordpress.org/browser/smart-image-resize/)、 查看 [SVN 存放庫](https://plugins.svn.wordpress.org/smart-image-resize/)，或透過 [RSS](https://plugins.trac.wordpress.org/log/smart-image-resize/?limit=100&mode=stop_on_copy&format=rss) 訂閱[開發記錄](https://plugins.trac.wordpress.org/log/smart-image-resize/)。 ## 變更記錄 #### 1.15.1 * Various improvements and bugfixes. * Declared compatibility with WooCommerce v10.6 #### 1.15.0 * Added support for product brands * Various improvements and bugfixes. #### 1.13.1 * Declared compatibility with WooCommerce 10.3 #### 1.13.0 * Enhanced the “Bulk Regenerate Images” page for better user experience. * Various improvements and bugfixes. #### 1.12.1 * Admin tweaks for better user experience. #### 1.12.0 * Introduced a new filter `wp_sir_exclude_trim_sizes` that allows excluding certain image sizes from the whitespace trimming functionality. * Added support for AVIF format. * Admin tweaks for better user experience. * Fixed a compatibility issue with the new version of the Phlox theme. * Various improvements and bugfixes. #### 1.10.2 * Various improvements and bugfixes. #### 1.10.0 * Added support for Phlox theme. * Added an option to prevent upscaling of small images. * Introduced a dedicated “Help” tab featuring setup guides and troubleshooting resources. * Addressed an issue with some thumbnail regeneration plugins not using the edited version of images modified in WordPress’s built-in image editor * Enhanced the settings page to improve user experience. * Process image when `set_post_thumbnail` is called. * Improved compatibility with PHP 8.3 * Various minor bugfixes and stability improvements #### 1.8.1 * Declare compatibility with custom order tables for WooCommerce. #### 1.8.0 * Added a new experimental setting “Cropping mode”.
