Codcy Image Optimizer

Codcy Image Optimizer converts your existing JPEG and PNG images to WebP format in bulk — directly on your server, with no third-party API or paid subscription required.

WebP images are significantly smaller than JPEG and PNG files (typically 60–95% smaller), which leads to faster page loads, lower bandwidth usage, and better Core Web Vitals scores.

How it works:

1. Scan — Analyzes your entire Media Library. Shows total image count, file size, and format breakdown before any changes are made.
2. Review — You decide when to start. Nothing is changed until you click Start.
3. Optimize — Converts images in batches of 20. Originals are backed up automatically.
4. Report — A detailed summary shows converted count, space saved, average compression rate, and any errors.

Key features:

• Converts JPEG and PNG to WebP
• Automatic backup of original files to uploads/codcy-image-optimizer/backup/
• Skips images where WebP would be larger than the original
• Fixes EXIF orientation automatically (Imagick)
• Resumes from where it left off if interrupted
• Does not alter image dimensions or crop ratio
• No external API, no account required
• Works with Imagick (preferred) or GD Library

What it does NOT do (intentionally):

• Does not resize images
• Does not process GIF files (may contain animation)
• Does not delete backups automatically
