KushalPawar Performance Optimizer

FAQ

Will compressing my images reduce their quality?

Not visibly. The default quality of 85% is what most photographers consider visually lossless. You can raise it toward 95% for maximum fidelity or lower it toward 60% for the smallest files using the quality slider on the Images tab.

Does the plugin keep the original images?

Compression of the displayed sizes happens in place to save disk space, which is what most users want. WebP copies are generated as separate .webp files alongside the originals, so the source format is always preserved for the fallback.

My site uses a plugin that breaks when scripts are deferred. What do I do?

Add the offending script’s handle to the Do-not-defer list on the Scripts tab (one handle per line). The plugin already excludes jQuery and the block editor runtime by default, so script optimization never has to be all-or-nothing.

Is the page cache compatible with WooCommerce?

Yes. The plugin automatically skips caching for logged-in users, commenters, requests with query strings, and WooCommerce cart, checkout, and account pages. You can exclude additional URLs on the Caching tab.

Does the plugin send any of my data to a third party?

No. KushalPawar Performance Optimizer performs all of its work on your own server and never contacts any external service. It collects no personal data and phones home to nothing.

Which image library does the plugin use?

It automatically uses Imagick if your host provides it (better quality and metadata stripping), and falls back to PHP’s GD library otherwise. The Settings → General tab shows which one is active on your server.

Where are cached files stored, and how do I clear them?

Cached HTML lives in wp-content/cache/kushalpawar-performance-optimizer/. The cache clears itself automatically when you publish or edit content, receive a comment, switch themes, or change a plugin. You can also clear it manually with the Clear cache now button on the General tab.
