LightPIX Stealth Image Compression

LightPIX Stealth Image Compression automatically optimizes your images the moment you upload them to WordPress. No manual work needed — just upload and LightPIX handles the rest.

Third-Party Service

This plugin relies on the LightPIX API, an external image compression service, to process and compress your images.

• Service URL: https://uxbyissa.com/lightpix/
• Privacy Policy: https://uxbyissa.com/lightpix/
• What is sent: Image file data and compression quality setting
• What is returned: Compressed image data
• Data storage: Images are processed in memory and are never stored on the API server

By enabling the plugin and providing consent in the settings, you agree to send your images to this external service for compression.

Why LightPIX?

• Automatic — compresses images on upload, no extra clicks
• Smart — tries multiple compression methods and picks the smallest result
• Safe — never saves a compressed image if it’s larger than the original
• Complete — compresses the original image AND all generated thumbnail sizes
• Fast — powered by Sharp engine with mozjpeg and WebP support

Features

• Automatic compression on upload (JPEG, PNG, WebP)
• Adjustable compression quality from 10% to 100%
• Bulk optimize all existing images in your media library
• Compresses all WordPress-generated thumbnail sizes
• Real-time compression statistics dashboard
• API connection status indicator
• Smart detection of already-optimized images
• Auto-resize for images larger than 4096px
• Batch processing to prevent server timeouts
• Secure — all requests use nonce verification and capability checks

How It Works

1. You upload an image to WordPress
2. WordPress generates all thumbnail sizes
3. LightPIX sends each image to the compression API
4. The API tries JPEG (mozjpeg), lower quality JPEG, and WebP compression
5. The smallest result is saved back — only if it’s smaller than the original
6. Statistics are updated automatically

Supported Formats

• JPEG / JPG
• PNG
• WebP

Requirements

• WordPress 5.0 or higher
• PHP 7.4 or higher
• Active internet connection (for API communication)
