<h3>External services</h3>
<p>This plugin connects to the ImgSmaller API to compress images and retrieve plan/quota information.</p>
<p>What is the service and what is it used for?<br />
– The ImgSmaller API (https://imgsmaller.com) provides image compression and account information used by this plugin to optimize your Media Library and display plan/quota details.</p>
<p>What data is sent and when?<br />
– When you start compression, the plugin sends the public URL of each selected attachment (or a secure, tokenized proxy URL if the file is not publicly accessible) along with your API key to request compression. After polling completes, the plugin downloads the optimized image bytes.<br />
– When viewing plan info, the plugin requests your current plan usage and limits using your API key.</p>
<p>Where can I find the service policies?<br />
– Terms of Service: https://imgsmaller.com/terms<br />
– Privacy Policy: https://imgsmaller.com/privacy</p>
<p>Notes:<br />
– You can disable background processing at any time from the dashboard. If you prefer not to send any files or metadata, do not start compression and do not enter an API key.</p>

MegaOptim

<p>MegaOptim 2.0 is a WordPress image optimization plugin built for sites that want to optimize images and move older JPG, PNG, and GIF libraries to next-gen formats like WebP and AVIF. You can convert images, compress originals, optimize supported next-gen images, process the Media Library or server folders in bulk, and deliver the best available format automatically on the front end.</p>
<p>If your goal is to convert JPEG to WebP, convert PNG to WebP, generate AVIF versions for better performance, optimize existing WebP and AVIF assets, or use smart compression instead of fixed local compression, MegaOptim 2.0 is designed around that workflow. Next-gen format generation is a major focus of this release, but 2.0 is not limited to conversion only.</p>
<h4>Why Use MegaOptim?</h4>
<ul>
<li>Optimize supported JPEG, PNG, GIF, WebP, and AVIF images</li>
<li>Convert JPEG, PNG, and GIF images to WebP and AVIF</li>
<li>Bulk process the WordPress Media Library</li>
<li>Browse and process folders outside the Media Library</li>
<li>Use fixed local compression or smart MegaOptim Cloud compression</li>
<li>Automatically convert or compress newly uploaded images</li>
<li>Serve WebP and AVIF with Apache <code>.htaccess</code> or PHP passthru</li>
<li>Track background jobs with a built-in queue monitor</li>
<li>Restore compressed originals from backup or remove generated next-gen files</li>
<li>Optionally process retina images generated by WP Retina 2x / Perfect Images</li>
<li>Use WP-CLI for bulk conversion, stats, reset, logs, and queue tools</li>
</ul>
<h4>Conversion-First Workflow</h4>
<p>MegaOptim 2.0 keeps your original uploads in place and generates next-gen derivatives alongside them. That means you can convert older JPG, PNG, and GIF images to WebP or AVIF without replacing the original source file. On the front end, MegaOptim can serve the best format supported by the visitor’s browser while keeping the original file available as a fallback.</p>
<h4>Local vs Cloud Processing</h4>
<p>MegaOptim works without an API key. If your server has GD or Imagick support, you can do local processing for WebP conversion, local AVIF generation when your server supports it, and basic local compression for JPEG and PNG images. Local compression is useful when you want a simple, fixed local workflow on your own server.</p>
<p>If you add a MegaOptim API key, MegaOptim Cloud can offload processing from your server and is the recommended option for smart compression, original-format compression, direct WebP and AVIF optimization, and broader AVIF workflows. This is the better path when you want smarter results than fixed local compression. The cloud plan is available for just <strong>$49 per year</strong> and can be used on <strong>unlimited sites</strong>. You can get an API key from <a href="https://app.megaoptim.com/" rel="noopener noreferrer nofollow ugc">the MegaOptim dashboard</a> and see plans at <a href="https://megaoptim.com/pricing/" rel="noopener noreferrer nofollow ugc">MegaOptim pricing</a>.</p>
<h4>What MegaOptim 2.0 Can Do</h4>
<ul>
<li>Convert mode: Generate WebP or AVIF versions from JPEG, PNG, and GIF images</li>
<li>Compress mode: Optimize original images with fixed local compression or smart cloud compression, and optionally generate next-gen formats during compression</li>
<li>Next-gen optimization: Optimize existing WebP and AVIF images through the cloud compression workflow</li>
<li>Media Library view: Process individual images, selected images, or run bulk jobs across the library</li>
<li>File System view: Browse folders on your server and bulk-convert images outside the Media Library</li>
<li>Upload automation: Automatically convert or compress new uploads in the background</li>
<li>Delivery settings: Choose Apache <code>.htaccess</code> rules or PHP passthru rewriting to serve WebP and AVIF</li>
<li>Queue monitor: Watch active jobs, progress, failures, and background processing state</li>
<li>Tools page: Run restore actions for compressed originals or remove generated WebP/AVIF derivatives</li>
<li>Restore support: Restore compressed images from backup and regenerate thumbnails</li>
<li>Logging and diagnostics: Use the built-in log viewer and queue statistics through WP-CLI</li>
<li>Retina support: Optionally process <code>@2x</code> images created by WP Retina 2x or Perfect Images</li>
</ul>
<h4>Migration From Older MegaOptim Versions</h4>
<p>MegaOptim 2.0 includes background migration for legacy settings and older attachment data. Existing users can upgrade and let MegaOptim migrate data in batches, with progress shown inside the admin UI while migration is running.</p>
