Stintlief WebP Converter

Automatically convert uploaded images to optimized WebP format with safe fallbacks, optional backups, and easy restoration.

Soovex WebP Converter is a powerful, feature-rich WordPress plugin that automatically converts your media library images (JPG, PNG) to modern WebP format. This image optimization plugin significantly reduces file sizes by 25-35% while maintaining excellent visual quality, resulting in faster page load times, improved Google PageSpeed scores, better SEO rankings, and reduced bandwidth usage.
Why Use WebP Image Format? 
WebP is a modern image format developed by Google that provides superior compression compared to traditional JPEG and PNG formats. It offers both lossless and lossy compression, allowing you to achieve smaller file sizes without sacrificing image quality. WebP images load faster, consume less bandwidth, improve Core Web Vitals scores, and enhance user experience – especially on mobile devices. All modern browsers support WebP, and this plugin automatically serves WebP to compatible browsers while falling back to original formats for older browsers.

<ul>
<li>Unlimited Image Conversions: Convert unlimited JPG/PNG images to WebP format with no restrictions</li>
<li>One-Click Conversion: Convert single, multiple, or all images with simple one-click operations</li>
<li>Smart Backup System: Automatically creates secure backups of original images before conversion</li>
<li>Media Library Integration: Seamlessly convert images directly from WordPress media library</li>
<li>Bulk Processing: Convert single, multiple, or all images at once with background processing</li>
<li>URL Conversion: Convert images from external URLs and save to media library</li>
<li>Quality Control: Adjustable WebP compression quality (40-100) for optimal balance</li>
<li>Auto-Convert Uploads: Automatically convert new image uploads to WebP format</li>
<li>Revert Functionality: Restore original images from backups anytime with one click</li>
<li>Activity Logging: Comprehensive activity log tracking all conversions, failures, and reversions</li>
<li>Real-Time Statistics: Monitor conversion stats, storage savings, and performance metrics</li>
<li>Modern Dashboard: Beautiful, intuitive dashboard with conversion statistics and quick actions</li>
<li>Lazy Loading Support: Optional native lazy loading for improved page performance</li>
<li>Browser Compatibility: Automatic fallback to original images for unsupported browsers</li>
<li>Server Health Check: Built-in server requirements verification and status monitoring</li>
<li>Backup Management: Flexible backup retention settings with automatic cleanup options</li>
<li>SEO Optimization: Improves Google PageSpeed scores and Core Web Vitals</li>

<li>The conversion will process all eligible images in your media library</li>
</ul>
Warning: This action will convert all images. Make sure you have backups enabled if you want to keep originals.
<h4>Compression Settings</h4>
Image Compression Quality 
Control the balance between image quality and file size.
Quality Levels: 
* 40-60%: High compression, smaller file size, noticeable quality loss 
* 60-80%: Balanced compression, good quality with reasonable file size (recommended) 
* 80-100%: Low compression, larger file size, minimal quality loss
Recommended: 80-85% provides an excellent balance between quality and file size for most websites.
<h4>Backup & Recovery</h4>
Enable Data Backup 
Keep original images as backup after conversion. This allows you to revert conversions if needed.
Benefits: 
* Original images are preserved in a backup folder 
* You can revert any conversion at any time 
* Provides safety net for all conversions
Note: Backups use additional storage space. Monitor your disk usage if you have many images.
Backup Reminder 
Get notified before backup data is automatically deleted.
When enabled, you’ll receive admin notices 3 days before backups are scheduled for deletion, giving you time to take action if needed.
Automatically Delete Original Data from Backup 
Set how long to keep backup files before automatic deletion.
Options: 
* 7-365 days: Keep backups for a specific duration 
* Custom: Set your own duration (1-3650 days) 
* Never: Keep backups permanently (uses more storage)
Critical: Once deleted, original images cannot be recovered. Ensure you have backups elsewhere if needed.
All Data Recovery (Revert All) 
Revert all converted images back to their original format.
This action will restore all converted WebP images to their original JPEG/PNG format using the backup files. Only works if backups are enabled and available.
<h4>Auto Features</h4>
Auto-convert New Uploads 
Automatically convert images to WebP when they are uploaded to the media library.
How it works: 
* When enabled, all new JPEG/PNG uploads are automatically converted 
* Conversion happens in the background after upload 
* Original images are kept as backup (if backup is enabled) 
* No manual intervention required
Requirement: Auto-convert requires backup to be enabled. If backup is disabled, auto-convert will also be disabled.
Enable Lazy Loading 
Improve page load times by loading images only when they enter the viewport.
Benefits: 
* Faster initial page load times 
* Reduced bandwidth usage 
* Improved performance on mobile devices 
* Better user experience on image-heavy pages
Lazy loading adds the native “loading=’lazy'” attribute to all img tags. Modern browsers support this natively without additional JavaScript.
Serve WebP Images 
Automatically serve WebP images to browsers that support them for better performance.
How it works: 
* Browsers that support WebP receive the optimized WebP version 
* Older browsers automatically receive the original format 
* No changes needed to your theme or content 
* Works transparently in the background
Compatibility: All modern browsers support WebP. Older browsers will automatically fall back to original formats.
<h4>Activity Log</h4>

Click the “Retry” button next to any failed conversion in the Activity Log to attempt the conversion again. Useful if the failure was due to temporary issues.
Clear Logs 
Clear all activity log entries.

* Enable lazy loading for better performance
Performance Tips: 
* Use batch conversion for many images

<h4>Server Requirements</h4>

<ul>
