## Description
**KushalPawar Performance Optimizer** makes your WordPress site faster automatically—
no tuning required. Activate it and it starts compressing images, lazy-loading off-
screen media, deferring render-blocking scripts, and caching your pages. Everything
runs locally on your own server, and the plugin never sends any data anywhere.
#### Features
* **Automatic image compression** — every new upload is compressed (JPEG/PNG) with
a configurable 60–95% quality slider. 85% is visually lossless for most photos.
* **WebP conversion with fallback** — generates modern WebP copies and serves them
via a `` element, falling back to the original for browsers that don’t
support WebP. Works for content images, featured images, and responsive `srcset`
variants.
* **Bulk media optimization** — one click compresses your entire existing media
library, with a live progress bar.
* **Lazy loading** — adds `loading="lazy"` to images and iframes, while keeping
your first images eager so above-the-fold content stays instant.
* **Script optimization** — adds `defer` to non-critical scripts and loads non-
critical CSS asynchronously, with a safe-mode exclusion list for scripts that
should not be deferred.
* **Inline CSS minification** — strips comments and whitespace from inline style
blocks.
* **Page caching** — a fast file-based cache for anonymous visitors, stored in `
wp-content/cache/kushalpawar-performance-optimizer/`, with smart invalidation
on content, comment, theme, and plugin changes.
* **Speed score dashboard widget** — shows an estimated before/after load time,
image weight saved, images optimized, and cache hit rate. Calculated locally —
no external API call.
* **Native settings UI** — a clean tabbed screen under Settings KushalPawar Performance
Optimizer, built with WordPress admin components and vanilla JavaScript.
## Installation
1. Upload the `kushalpawar-performance-optimizer` folder to the `/wp-content/plugins/`
directory, **or** install it directly from **Plugins Add New** in your WordPress
dashboard.
2. Activate the plugin through the **Plugins** menu in WordPress.
3. Go to **Settings KushalPawar Performance Optimizer** to configure modules. Sensible
defaults are applied automatically, so the plugin starts optimizing immediately.
4. (Optional) On the **Images** tab, click **Start bulk optimization** to compress
images you’ve already uploaded.
## 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.
