Image Optimizer Module for OpenCart V4 optimises all images on your site, from product images to category images and banner images. It uses the most complex algorithms and image processing techniques, which reduce file sizes and maintain high visual quality. You can also set rules for automatic optimisation so that all images that are uploaded into your store are optimised on the fly. 

Key Features

1. Automatic Image Compression:
   • The module automatically compresses images, thereby reducing their file size without any quality loss that is noticeable.
   • It supports multiple compression levels, thus giving you the control over the trade-off between file sizes and quality.
2. Image Format Conversion:
   • It supports converting images into modern formats like WebP, which is lightweight and thus optimised for the web to make for faster load times. 
   • It automatically serves WebP images to browsers that support it and continues to serve JPEG/PNG to browsers that do not.
3. Resizing and Scaling Options:
   • Offers custom resizing options, allowing you to adjust image dimensions based on your store’s design requirements. 
   • You can set different sizes for thumbnail, medium, and full-sized images, reducing the load on high-resolution images. 
4. Bulk Optimisation:
   • Optimise all existing images in bulk, which is especially useful for stores with a large product catalog. 
   • Batch processing lets you choose categories or sections of your website that you want to optimise without interfering with any other areas of your website. 
5. Lazy Loading:
   • Enable lazy loading, so images are only loaded when about to appear within the viewport of the user. This decreases the initial load time for pages that may have multiple images.
6. Integration with Cloud Services:
   • The module is also fully compatible with popular image optimisation cloud services such as TinyPNG and Kraken.io, using strong APIs to get a more compressed conversion. 
7. Compatibility and Multilanguage Support:
   • It supports the latest version of OpenCart, which is V4, and also offers multiple languages. 
   • Supports Easy Custom Themes and Extensions Integration
8. Automatic Backup & Restore:
   • Module takes an automatic backup of your images before optimising and gives you a restore option in case you want your original file. 
   • It allows rolling back image changes in case some adjustments are needed.

Benefits

1. Improved Loading Speed:
   • Optimised images decrease page-loading time by up to tens of percentages a very powerful factor in driving user engagement and retention. Faster load times will also provide a faster shopping experience, particularly with mobile clients who have slower data connections in most places. 
2. Better SEO:
   • Since Google considers page speed as a ranking factor, optimizing images enhances your site’s SEO performance. Faster-loading pages are indexed more favorably by search engines, helping your products rank higher in search results.
3. Reduced Bandwidth Usage:
   • Smaller image sizes mean less data usage, which can lower hosting costs and make the site faster for users on limited data plans.
4. Enhanced User Experience:
   • Lazy loading ensures that the user views the content he needs without waiting for all images to load, which is especially important on mobile devices where network speeds are unpredictable. 
5. Mobile-Friendly Optimization:
   • The new image formats, such as WebP, are optimised for both desktop and mobile platforms. It ensures a seamless experience on all devices. The pages load faster, and the users get a smooth browsing experience on mobile.
6. Easy Management & Maintenance:
   • The automatic backup and restore feature makes management easier as you can revert changes if needed. Bulk processing reduces manual work, making it easier to manage large product catalogs. 
7. Reduced Bounce Rate:
   • Faster and smoother site performance reduces bounce rates, as visitors are more likely to stay on a website that loads quickly and provides a seamless browsing experience.
8. Cost Efficiency:
   • The module helps in reducing bandwidth and storage requirements, thus bringing down the operating costs associated with large image files and high traffic volumes.
