Image Optimizer for OpenCart helps you reduce image weight, speed up page loading, and manage image optimization across large OpenCart catalogs. It combines compression for PNG, JPG, JPEG, and GIF images, WebP and JP2 conversion, Lazy Load, and flexible processing controls to support lighter image delivery without noticeable quality loss. This is not just a WebP converter or a basic image compressor, but a complete image optimization tool for OpenCart stores.

How it works?

• Choose the compression quality and conversion mode that fit your store’s image strategy.
  
• Preview before bulk processing so you can compare the original and optimized image with confidence.
  
• Process the full image library or optimize only selected folders when you need to update specific image groups.
  
• Run image optimization manually or schedule it with CRON for routine processing.
  
• Control server load by limiting how many images are processed per request or CRON run, especially on larger stores.
  
• Keep original images or replace original images with optimized versions when disk space matters.
  
• Restore original images if you need to roll back the applied changes.]

• Preview optimization results before bulk processing.
  
• Restore original images anytime if you need to roll back changes.
  
• Replace original images with optimized versions to free up more disk space.
  
• Control how many images are processed per CRON run to avoid extra server load on large stores.
  
• Generate a dynamic XML image sitemap to help search engines discover and crawl image content more efficiently.
  
• Compress PNG, JPG, JPEG, and GIF images to reduce file size without noticeable quality loss.
  
• Convert images to WebP and JP2 to deliver lighter image formats across the storefront.
  
• Enable Lazy Load for product, theme, module, CMS, logo, and other site images.
  
• Optimize unlimited images across image-heavy OpenCart catalogs.
  
• Adjust compression and conversion settings to match your store’s performance and storage efficiency goals.
  
• Add GZIP compression for extra performance support.

FAQ
Will image optimization affect visual quality on the storefront?
The module is designed to compress and convert images without noticeable visual quality loss. You can also use the preview before processing option to compare results.
How can I reduce server load during bulk image processing?
You can control how many images are processed per request and per CRON run. This helps handle optimization safely on larger stores and lighter hosting environments.
Can I optimize only newly added or recently updated images?
Yes. The module can process images from a selected folder, which is useful for optimizing specific groups instead of the full library.
Can I save disk space by replacing original images?
Yes. The module includes an original image replacement option in the settings to reduce disk usage.
