Shrinkify Image Compression

Shrinkify Image Compression is the easiest way to drastically reduce your image file sizes without compromising quality. Powered by the Shrinkify cloud engine, it automatically converts your heavy JPEG and PNG images into modern, ultra-efficient formats like AVIF and WebP — the same formats used by Google, Netflix, and top-performing websites worldwide. 🚀 Why Shrinkify?

• Blazing Fast Optimization — Cloud-powered compression delivers results in seconds, not minutes.
• Next-Gen Formats — Full support for AVIF, WebP, optimized PNG, and JPEG output.
• Auto-Optimize on Upload — Every new image is compressed the moment it hits your media library. Zero effort required.
• Deep Thumbnail Optimization — Compresses all WordPress-generated image sizes, not just the original.
• Smart Scale Down — Automatically resize oversized uploads to a configurable max width before compression.
• Bulk Batch Processing — Optimize your entire existing media library with a secure, browser-synced batch engine.
• Automatic URL Replacement — Seamlessly updates all image references across posts, pages, and metadata.
• Beautiful Dashboard — A clean, modern admin panel with dark mode, live stats, and real-time progress tracking.
• Lightweight & Fast — No bloat, no unnecessary dependencies. Built for performance.

🔒 Your Images Are Safe Images are securely transmitted to the Shrinkify API via HTTPS, optimized in real-time, and returned to your server. Originals are never stored on our servers — they are purged immediately after processing.

1.3

• Security: Replaced direct file operations (file_get_contents/file_put_contents) with WP_Filesystem API for WordPress coding standards compliance.

• Fix: Resolved duplicate filename collision — images with the same name now get unique filenames (e.g., photo-1.webp) using wp_unique_filename(), matching WordPress default behavior.
• Fix: Resolved race condition on usage and saved bytes counters using atomic database updates.
• Fix: Removed error-suppressing @ operators from file operations for better debugging.
• Fix: All error_log() calls now wrapped in WP_DEBUG checks for production safety.
