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>
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>
Viewing Activity Log 
Track all conversion activities, including successful conversions, failures, and reversions.
Information displayed: 
* Original Image: Name of the source image 
* WebP Image: Name of the converted WebP file 
* Status: Conversion status (Converted, Failed, Reverted) 
* Date: When the action occurred
Revert Single Image 
Revert a single converted image back to its original format.
Click the “Revert” button next to any converted image in the Activity Log to restore it to its original format. Only available for successfully converted images with backups.
Retry Failed Conversion 
Retry a conversion that previously failed.
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.
Use the “Clear Logs” button to remove all activity log entries. This action cannot be undone but does not affect your images.
<h4>Advanced Options</h4>
Reset Everything 
Reset all plugin settings and data to default values.
This action will: 
* Revert all converted images to original format 
* Clear all activity logs 
* Reset all settings to default 
* Delete all backup files
⚠️ This action cannot be undone!
<h4>Tips & Best Practices</h4>
Recommended Settings: 
* Enable backups for safety 
* Set compression quality to 80-85% 
* Enable auto-convert for new uploads 
* Enable lazy loading for better performance
Performance Tips: 
* Use batch conversion for many images 
* Monitor disk space with backups enabled 
* Check Activity Log regularly 
* Test compression quality on sample images first
<h4>Server Requirements</h4>
Server Health Check 
The plugin includes a built-in server health check feature that verifies:
<ul>
<li>GD Extension: Must be enabled for image processing</li>
<li>WebP Support: GD extension must support WebP format</li>
<li>Memory Limit: Recommended minimum of 128MB</li>
</ul>
Note: If WebP support is not available, contact your hosting provider to enable GD extension with WebP support.

Using the <code>[currency]</code> shortcode you can convert one currency to another. The conversion is based on the rates published by the ECB. You can change from and to any of the supported currencies.
The <code>[currency_legal]</code> shortcode outputs a disclaimer text and a link to the ECB eurofxref page.
<h4>Important!</h4>
ECB advices against using their rates for transaction purposes. From their site: “The reference rates are published for information purposes only. Using the rates for transaction purposes is strongly discouraged.”
The reference rates are usually updated by ECB at around 16:00 CET every working day, except on <a href="https://www.ecb.europa.eu/services/contacts/working-hours/html/index.en.html" rel="nofollow ugc">TARGET closing days</a>.
Go to the <a href="https://www.ecb.europa.eu/stats/policy_and_exchange_rates/euro_reference_exchange_rates/html/index.en.html" rel="nofollow ugc">ECB site</a> for more information and disclaimers.
Also note that conversion from non-Euro to non-Euro is done through the Euro, so GBP to USD is calculated as GBP → EUR → USD (converted 2 times).
This plugin is based on a plugin by <a href="http://www.xclamationdesign.co.uk/free-currency-converter-shortcode-plugin-for-wordpress/" rel="nofollow ugc">Xclamation</a>.
Also see <a href="https://github.com/joostdekeijzer/wp_eurofxref" rel="nofollow ugc">wp_eurofxref on GitHub</a> where development takes place.
<h3>Shortcode usage & examples</h3>
<h4>currency_legal shortcode</h4>
This shortcode returns the string ‘* For informational purposes only. Exchange rates may vary. Based on <a href="https://www.ecb.europa.eu/stats/policy_and_exchange_rates/euro_reference_exchange_rates/" rel="nofollow ugc">ECB reference rates</a>.’
The prepended ‘* ‘ (the same string as the [currency] append string) can be changed using the ‘prepend’ attribute.
For example: <code>[currency_legal prepend='Please note: ']</code>
If you want to change the default prepent string for your whole site you can use the default <code>shortcode_atts_currency_legal</code> filter. 
See the <a href="https://developer.wordpress.org/reference/hooks/shortcode_atts_shortcode/" rel="nofollow ugc">shortcode_atts_{$shortcode} reference</a> for more information about this.

<ul>
<li><code>from</code>: currency code (default: EUR)</li>
<li><code>to</code>: currency code (default: USD)</li>
<li><code>amount</code>: number of “from” currency (default: 1)</li>

<li><code>append</code>: string (default ‘&nbsp;‘ which is displayed as ‘ ‘ in the browser); string put after conversion. The * references the disclaimer text, see [currency_legal] shortcode.</li>
<li><code>round: boolean</code> (default true); Round numbers to whole units.</li>
<li><code>round_append</code>: string (default ‘=’); replaces decimals</li>
<li><code>no_from_show_rate</code>: boolean (default true); when from amount is hidden in the output the “to” text gets a tooltip that displays the exchange rate. The element with this tooltip is styled with the <code>to_style</code> css string below. Set the <code>no_from_show_rate</code> option to false to disable the and tooltip.</li>
<li><code>to_style</code>: css string (default ‘cursor:help;border-bottom:1px dotted gray;’); styling of “to” text wrapper.</li>
