<p>Every time you upload an image, WordPress and your theme create several extra copies — often eight to ten files per image. On shared hosting with inode (file count) limits, this fills your quota fast, slows down backups, and wastes disk space.</p>
<p><strong>ShinPix</strong> gives you back control:</p>
<ul>
<li><strong>Choose which image sizes are generated.</strong> See every size registered by WordPress and your theme, with dimensions, and disable the ones you do not use.</li>
<li><strong>See your savings.</strong> ShinPix shows how many files each upload stores now versus the maximum, so you can see the inodes you save at a glance.</li>
<li><strong>Safe by default.</strong> ShinPix flags the sizes the WordPress admin and block editor rely on, and warns you before you disable them.</li>
<li><strong>Cap oversized uploads.</strong> Automatically scale down huge phone photos (often 4000px+) to a sensible maximum, keeping web quality while cutting file size.</li>
<li><strong>Convert to WebP.</strong> Create a lighter WebP copy of every new upload and serve it automatically to browsers that support it — with the original kept as a fallback. ShinPix detects whether your server can produce WebP and disables the feature gracefully if it cannot.</li>
<li><strong>Compress on upload.</strong> Set the quality used for the images WordPress generates, so every size is leaner.</li>
<li><strong>Optimize your existing library.</strong> Scan what is already in your Media Library and convert it to WebP in the background, batch by batch, with a progress bar you can pause and resume. Optimize or re-optimize a single image right from the Media Library, and retry anything that failed.</li>
</ul>
<p>ShinPix is built for the real world of budget shared hosting. It is lightweight, adds no front-end overhead, and only changes what happens at upload time.</p>
<p><strong>Coming soon (and on the roadmap):</strong></p>
<ul>
<li>AVIF conversion (Pro)</li>
<li>Scheduled, fully automatic background processing (Pro)</li>
<li>Offload to S3, Cloudflare R2, Wasabi and other object storage to remove image files from your server entirely</li>
</ul>
<p>ShinPix is part of the <strong>ShinKit</strong> family of WordPress tools.</p>


ShinPix – Image Optimizer & Size Control

Control which thumbnail sizes WordPress generates, cap oversized uploads, and convert images to WebP — built for shared hosting.

YoOhw Studio

<p>Thumbnail Manager helps you control WordPress thumbnail generation, regenerate image sizes, and clean unused thumbnail files from the Media Library.</p>
<p>Use it after changing themes, installing WooCommerce, disabling custom image sizes, or cleaning up years of generated media files. The plugin focuses on predictable thumbnail management: choose which image sizes should stay enabled, rebuild the thumbnails you need, preview cleanup results, then delete only reviewed generated files.</p>
<p>Cleanup is metadata-aware and safety-focused. Thumbnail Manager validates uploads paths, protects original full-size images, runs prune/delete actions in batches, and updates attachment metadata after deleted thumbnail sizes are removed.</p>
<h4>Key Features</h4>
<ul>
<li>Regenerate WordPress thumbnails for existing image attachments</li>
<li>Generate only missing thumbnails or force-regenerate all selected images</li>
<li>Disable unwanted registered image sizes for future uploads</li>
<li>Prune unused thumbnails while keeping selected sizes</li>
<li>Run Dry-run previews before deleting generated thumbnail files</li>
<li>Detect legacy thumbnail sizes stored in attachment metadata</li>
<li>Report disk-only orphan matches without deleting unmapped files by default</li>
<li>Scan recommendations based on protected sizes, WooCommerce-related sizes, generated metadata, and common content references</li>
<li>Process large Media Libraries with cursor-based AJAX queues and folder scoping</li>
<li>Manage everything from Tools > Thumbnail Manager</li>
</ul>
<h4>Common Use Cases</h4>
<ul>
<li>Clean WordPress thumbnail bloat after theme or page builder changes</li>
<li>Regenerate thumbnails after changing Media Settings or custom image sizes</li>
<li>Reduce WooCommerce image storage by reviewing generated product thumbnails</li>
<li>Disable image sizes that should no longer be created for new uploads</li>
<li>Rebuild missing thumbnails after migration, restore, or failed image processing</li>
<li>Audit legacy thumbnail sizes left behind by old themes and plugins</li>
</ul>
<h4>Safety First</h4>
<p>Thumbnail Manager is designed for controlled cleanup, not blind filesystem deletion.</p>
<ul>
<li>Original full-size images are not deleted</li>
<li>Delete mode requires a fresh delete token and a completed scan</li>
<li>Dry-run mode never deletes files</li>
<li>Cleanup targets files from attachment metadata</li>
<li>Disk-only orphan matches are reported, not deleted by default</li>
<li>Paths are validated under the WordPress uploads directory before deletion</li>
<li>Attachment metadata is updated after generated thumbnail sizes are removed</li>
</ul>
<h4>What It Does Not Do</h4>
<ul>
<li>It does not compress or optimize image quality</li>
<li>It does not replace image optimization or CDN plugins</li>
<li>It does not automatically delete media without confirmation</li>
<li>It does not delete original uploaded images</li>
<li>It does not unregister image sizes from themes or plugins</li>
</ul>
<h3>Usage</h3>
<h4>Recommended Workflow</h4>
<ol>
<li>Open Tools > Thumbnail Manager.</li>
<li>Scan Recommendations to review likely keep/remove sizes.</li>
<li>Apply recommended sizes if they match your site.</li>
<li>Open Thumbnail Sizes and save the sizes you want generated for future uploads.</li>
<li>Run Regenerate to rebuild missing or selected thumbnails.</li>
<li>Open Prune Files and run Dry-run before any deletion.</li>
<li>Review matched files, then switch to Delete only when the preview is correct.</li>
</ol>
<h4>Regenerate Thumbnails</h4>
<p>Use Regenerate when you need to rebuild WordPress image sizes for existing attachments. You can process all media, the current year, a specific uploads folder, or specific attachment IDs.</p>
<h4>Prune Files</h4>
<p>Use Prune Files to clean generated thumbnails for sizes you no longer want to keep. Always run Dry-run first. If orphan discovery is enabled, metadata-backed legacy sizes can be included, while unmapped disk-only matches are reported for review.</p>
<h4>Thumbnail Sizes</h4>
<p>Use Thumbnail Sizes to control which registered image sizes WordPress should generate for future uploads. This setting does not remove existing files until you run Prune Files.</p>
<h3>Technical Notes</h3>
<ul>
<li>Uses <code>intermediate_image_sizes_advanced</code> to control future thumbnail generation</li>
<li>Uses cursor-based AJAX queues for regenerate and prune scans</li>
<li>Uses attachment metadata for prune candidates</li>
<li>Validates filesystem paths under the uploads directory before deletion</li>
<li>Updates attachment metadata after generated thumbnail files are removed</li>
<li>Requires the <code>manage_options</code> capability</li>
<li>Works per site on multisite installations</li>
</ul>
<h3>Privacy</h3>
<p>Thumbnail Manager does not collect, store, or transmit personal data. All thumbnail scans, regeneration actions, and cleanup actions run locally on your WordPress site.</p>
