Codcy

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:
<ol>
<li>Scan — Analyzes your entire Media Library. Shows total image count, file size, and format breakdown before any changes are made.</li>
<li>Review — You decide when to start. Nothing is changed until you click Start.</li>
<li>Optimize — Converts images in batches of 20. Originals are backed up automatically.</li>
<li>Report — A detailed summary shows converted count, space saved, average compression rate, and any errors.</li>
</ol>
Key features:
<ul>
<li>Converts JPEG and PNG to WebP</li>
<li>Automatic backup of original files to <code>uploads/codcy-image-optimizer/backup/</code></li>
<li>Skips images where WebP would be larger than the original</li>
<li>Fixes EXIF orientation automatically (Imagick)</li>
<li>Resumes from where it left off if interrupted</li>
<li>Does not alter image dimensions or crop ratio</li>
<li>No external API, no account required</li>
<li>Works with Imagick (preferred) or GD Library</li>
</ul>
What it does NOT do (intentionally):
<ul>
<li>Does not resize images</li>
<li>Does not process GIF files (may contain animation)</li>
<li>Does not delete backups automatically</li>
</ul>
