Keep Originals Safe, convert JPEG/PNG images to WebP and makes WebP the canonical file. WP returns <code>.webp</code> URLs, Keeping originals safely archived.
<h3>How it works (high level)</h3>
<ol>
<li>
Convert
<ul>
<li>For a JPG/PNG attachment, the plugin generates a WebP for the full image and all WordPress-generated sizes.</li>
<li>Conversion is done through WordPress’ image editor system (WP_Image_Editor), meaning it uses GD or Imagick (whichever your server supports) with WebP support enabled.</li>
</ul>
</li>
<li>
Move originals
<ul>
<li>The original JPG/PNG files are moved to:
<ul>
<li><code>wp-content/uploads/_originals/...</code></li>
</ul>
</li>
<li>The folder structure mirrors your uploads structure.</li>
</ul>
</li>
<li>
Update WordPress to serve WebP
<ul>
<li>Attachment “file” + metadata are updated so WordPress serves <code>.webp</code> as the attachment file.</li>
<li>Attachment mime type is updated to <code>image/webp</code>.</li>
</ul>
</li>
<li>
Optional: Replace old URLs everywhere
<ul>
<li>If enabled, the plugin can replace old <code>.jpg/.png</code> URLs across:
<ul>
<li>post content</li>
<li>postmeta</li>
</ul>
</li>
<li>Replacement is serialized-safe (does not break serialized arrays).</li>
</ul>
</li>
</ol>
<h3>Background jobs (keeps running after page reload)</h3>
Conversion/repair/sweep jobs are designed to run in the background. They keep ticking even if you refresh the page or close the tab.
The plugin uses multiple loopback methods (admin-post / REST / public tick fallback) so it can keep working even on restrictive hosting setups.
<h3>Log + “it looks frozen” note</h3>
A rolling “terminal style” log is written to: 
– <code>wp-content/uploads/hsbc-webp-only/logs/webp-only.log</code>
If the log appears to freeze in the admin page: 
– click Refresh Log, or 
– refresh the page
The job may still be running server-side; refreshing the log/page usually catches up.
<h3>Usage</h3>
Go to Media → WebP Only.
<h3>Settings</h3>
<ul>
<li>Quality
<ul>
<li>WebP quality for conversion (0–100).</li>
</ul>
</li>
<li>Batch size
<ul>
<li>How many items to process per tick. Smaller batches reduce server load.</li>
</ul>
</li>
<li>Replace old .jpg/.png URLs across content + postmeta (serialized-safe)
<ul>
<li>Recommended if your site content contains hard-coded image URLs.</li>
</ul>
</li>
<li>Sweep Include / Exclude
<ul>
<li>Used by the Sweep tools to control which folders are scanned.</li>
</ul>
</li>
</ul>
<h3>Conversion Jobs (buttons)</h3>
Start Bulk Convert 
– Converts Media Library attachments (JPG/PNG) in batches. 
– Moves originals to <code>uploads/_originals/</code>. 
– Updates attachment metadata so WordPress serves <code>.webp</code>. 
– Optional URL replacement (content + postmeta).
Start Repair/Cleanup 
– Repairs inconsistencies if something was partially converted or moved. 
– Useful after restores/migrations or if some attachments have mismatched metadata. 
– Optional URL replacement.
Start Folder Sweep 
– Scans the filesystem for eligible images (based on your Sweep Include/Exclude rules). 
– Designed for sites with additional image folders beyond standard uploads. 
– Optional URL replacement.
Stop Job 
– Stops the currently running job.
<h3>Maintenance / Cleanup (buttons)</h3>
Delete duplicate _originals 
– Deletes backup files in <code>uploads/_originals/</code> *only when* an identical file already exists in <code>uploads/</code>. 
– This is a cleanup tool for situations where originals were restored back into uploads and you no longer need the archived duplicate.
Delete duplicate _webp 
– Removes orphaned WebP cache files in: 
 – <code>uploads/_webp/</code> 
– Only deletes WebP files that no longer match anything in <code>uploads/</code> or <code>uploads/_originals/</code>.
Delete duplicate sweep _originals 
– Maintenance cleanup for non-uploads roots (folders under <code>wp-content/</code>) that contain their own <code>_originals/</code> folders. 
– It uses your Sweep Include list to find those roots. 
– Only deletes a file from <code><root>/_originals/</code> when the same file exists at <code><root>/</code> AND the file size matches (safe duplicate).
Revert Everything 
– Restores original JPG/PNG files from <code>uploads/_originals/</code> back into <code>uploads/</code>. 
– Reverts attachment metadata so WordPress serves the originals again.
<h3>Log controls</h3>
Refresh Log 
– Pulls the latest log tail into the admin screen.
Reset Log 
– Clears the log file.
<h3>Requirements</h3>
<ul>
<li>WordPress’ image editor must support WebP.
<ul>
<li>GD with WebP support, or</li>
<li>Imagick with WebP support</li>
</ul>
</li>
<li>If WebP conversion is not supported on your server, conversion/repair/sweep will refuse to run (revert tools can still work).</li>
</ul>

<h3>Optimize the Images on Your Website, Drive More Conversions and Increase Your Speed Score</h3>
The QODE Optimizer plugin is developed to let you convert, compress and adjust file sizes for all the images on your website in a completely streamlined and quick manner. 
The plugin allows you to easily perform bulk or individual image optimization. 
You can convert JPG, PNG and GIF files, adjust default image width & height, as well as choose a compression method to be applied to images during the optimization. 
For Lossy compression methods, you can fine-tune the amount of compression applied, which in turn results in different image qualities.
<h3>The Easy Way to Remove Image Metadata</h3>
The QODE Optimizer provides you with a number of additional options related to images on your site. 
You can easily remove metadata for all the images on your website, thus reducing their respective file sizes even further.
<h3>Refine the Images Even Further by Converting them to the WebP Format</h3>
If you wish to convert your images to the supremely practical WebP format, the <a href="https://qodeinteractive.com/products/plugins/qode-optimizer-premium/" rel="nofollow ugc">QODE Optimizer</a> plugin has you covered.

<h3>Follow and Analyze the Process of Optimization in the System Log</h3>
By enabling the system log, you’ll be able to see all the steps that the system takes during the process of image optimization. 
This helps you further refine the optimization as you’ll be able to see precisely how the optimization affected each individual image in the process.

One more practical functionality allows you to set a background fill color for JPGs – this is particularly useful when converting images with transparent backgrounds to the JPG format. 
In addition to this, you can also have the original images deleted automatically after conversion, saving up even more in terms of memory.
