Image Optimizer [NAT]: Compress, Resize & Unused Images Cleaner
The ultimate all-in-one image optimization suite to free up your hosting storage, protect your photos, and speed up your storefront.

Compatibility: OpenCart 3.0.x, ocStore 3.0.x



What is the main problem with hosting space?
Every OpenCart store owner eventually faces running out of disk space, leading to higher hosting fees. You look into the image/catalog folder and see gigabytes of product photos.

Why does this happen?

• Unmerciful suppliers: They provide "raw" original photos (5-10 MB each) with huge resolutions (e.g. 5000x4000 px).
• Standard Compression Fails: Standard OpenCart settings and most other modules ONLY work with cached copies (image/cache). The heavy originals stay in image/catalog as dead weight.

What does the Image Optimizer [NAT] do?
This module is a professional toolkit designed to clean up your image/catalog folder, protect your assets, and speed up loading times. It provides the following key features:



1. Optimization & Resizing of Originals

• Resizing "Giants": Physically reduces high-resolution photos to reasonable limits (e.g. 1600px) while preserving proportions.
• Smart Compression: Resaves JPG, PNG, and WebP using optimal algorithms via GD or Imagick, removing unnecessary meta-info.
• Safety First: Use "Test Mode" to create compressed copies in a separate folder for verification.
• Apply Changes: Automatically move optimized files to the main catalog. You can choose to move old originals to Quarantine (Backup) or replace them permanently.

2. Unused Images Cleaner (Junk Remover)

• Smart Scanning: The module builds a whitelist by scanning your entire Database (products, categories, manufacturers) and Theme files (Twig, TPL, CSS, JS).
• Deep Analysis: It identifies files in your catalog folder that are NOT linked to any content and are just wasting space.
• Risk-Free Cleaning: Move junk files to a special catalog_trash folder first. If everything is fine, empty the trash with one click.

3. Dynamic Watermarks (Text & Images)

• Automatic Overlay: Automatically apply text or image watermarks to products, categories, manufacturers, banners, or blog images on-the-fly.
• Advanced Customization: Control transparency, rotation angle, position (9 standard zones), corner rounding, custom TTF fonts, and category inclusion/exclusion filters.

4. Automatic Placeholders

• Consistent Look: Display beautiful placeholder/fallback images for products, categories, or brands that do not have an image assigned in the database.

5. Modern Image Formats & Lazy Load

• Image format selection: Choose formats to optimize via checkboxes in settings.
• WebP delivery on-the-fly: Convert and deliver cache files as WebP on supported browsers dynamically.
• SVG support: Enable safe SVG upload and correct layout constraints in the frontend.
• Progressive Lazy Loading: Speeds up page loads with a blur-up effect (loads micro-previews first, then fades them in smoothly as the user scrolls).

6. Advanced Diagnostic Tools (pro)

• Diagnostics Tab: A brand new tab featuring 10+ professional tools.
• Filename Sanitizer: Automatically rename files and directories to strip Cyrillic characters, spaces, and special symbols for maximum server compatibility.
• Broken Database Links Checker: Clean up entries in your tables referencing missing files.
• Server Empty/Corrupt Files Cleaner: Scan and delete corrupted or 0-byte images.
• Heavy Files Finder: Locate and resize the largest files in your catalog.
• CMYK Converter: Transcode CMYK JPEGs to sRGB to fix colors in iOS/Safari.

7. Automated Tasks (Cron)

• Scheduled Scans: Set up automated directory optimizations in the background with fine-grained folder inclusions/exclusions.
• Multi-Task Support: Create multiple independent Cron tasks with unique configurations and names.

8. Real-time Disk Stats & Performance Dashboard

• Interactive Pie Chart: Track folder sizes (Catalog, Cache, Quarantine) in real time.
• Hosting Quota Overrides: Input hosting limits manually if PHP queries show physical partition limits. Features a configurable auto-load setting.

Technical Highlights:
