No. Existing Media Library images are not automatically bulk-optimized when you install or activate the plugin. Run Analyze Library and explicitly start Bulk Optimizer when you are ready.

It is a WordPress plugin. Upload its ZIP in Plugins → Add New Plugin → Upload Plugin, activate it, and use the Image Optimizer admin menu.

Fresh installations start with an Image Quality value of 70%. A recommended setup also uses WebP and a 2000 × 2000 pixel maximum resolution.

Yes. Click Skip for Now or the close button. Dismissing the popup does not start image conversion or apply new settings. You can reopen it in Settings.

The plugin readme lists WordPress 6.0 or newer and PHP 7.4 or newer. Output format support also depends on the image-processing libraries available on your server.

The page scanner recognizes supported Elementor image and background references stored as local Media Library attachments. Some dynamic or external images may not be resolved.

You can select WebP, AVIF, JPEG or PNG, provided that your hosting server can write the chosen format.

No. AVIF creation requires compatible local encoder support. The plugin checks writer availability and can report unsupported formats. WebP may be an alternative.

For lossy outputs such as JPEG, WebP and AVIF, generally yes: lower Image Quality percentages apply stronger compression, with visual trade-offs. Higher percentages favor detail. PNG uses lossless compression effort instead.

PNG output remains lossless in the plugin workflow. Its percentage controls compression effort rather than reducing visual pixel quality. File size savings depend on the actual image.

Yes. Configure maximum width and maximum height. Oversized images are reduced proportionally and smaller images are not upscaled.

Yes. Advanced options allow include-only or exclude-selected input formats, including JPEG, PNG, WebP, AVIF, GIF, BMP, TIFF, HEIC and HEIF.

Animated GIFs are protected from unsafe conversion that could flatten the animation into a single still frame.

Yes. Manual or page-level re-optimization can run again when format, Image Quality or maximum resolution changes. An exact matching profile may be skipped to avoid needless recompression.

Dry Run evaluates eligible or skipped images and estimated output size using temporary processing where applicable. It is designed not to replace live attachments or create optimization history and rollback snapshots.

Yes. Use Optimize by Page to scan a page, post or supported public custom post type, then choose the images to optimize from the detected local Media Library attachments.

It looks for featured images, common WordPress content/image markup, Gutenberg image and gallery references, local Media Library URLs and supported Elementor image/background data.

Potentially. WordPress attachments are shared resources. If the same attachment is used on multiple pages, changing it can affect all of those uses.

No. Page scanning can identify external image references, but the plugin does not silently download or modify remote-only files.

Go to Bulk Optimizer, review settings and optionally run Analyze Library. Click Start Bulk Optimization when you explicitly want to process the existing Media Library.

The admin dashboard uses live status updates and a secure worker flow to show processed, converted and skipped counts. Server timeouts or hosting constraints can still delay individual jobs.

Yes. The Bulk Optimizer provides pause, resume and cancel controls, although a currently running image operation may need to finish its safe processing slice.

Possible reasons include an identical optimization profile, an animated GIF, an unsupported format writer, memory safeguards, source policy rules or a generated file that does not meet the configured savings threshold.

When a valid retained snapshot is available, you can restore a previous image state in History & Rollback. A short-lived Undo action may also appear after certain single-image operations.

The versioned rollback system can retain up to three pre-optimization states per attachment, depending on retention configuration and available storage.

Yes. Bulk Runs can include Restore This Run. The plugin aims to revert successful conversions while skipping missing backups and images changed after that run.

The backup-flush action is intended to remove plugin-owned snapshots rather than your current live Media Library files. You will lose restore points that were deleted.

They are stored in plugin-managed locations on your WordPress server. They occupy storage and may be included in your host or site backups.

No external image processing API is required by the plugin. It relies on local server encoder capabilities and bundled browser-side helper assets.

The plugin documentation states it does not send conversion analytics or image files to United Web Host and does not create tracking cookies. Your WordPress site and hosting provider may separately collect logs or use other services.

Smaller images may reduce transfer size and improve some loading experiences, but the outcome depends on caching, layout, image delivery and hosting. SEO ranking or PageSpeed score improvements are not guaranteed.

Pause the job, reduce simultaneous heavy server tasks and check server resources and PHP error logs. Image conversion can be CPU and memory intensive on limited hosting.

Yes. The Download Plugin buttons on this site provide the bundled v3.0.1 installer. The site itself is a separate documentation and product website.
