Effortless Simple Image Optimiser hooks directly into the WordPress Media Library upload pipeline and compresses, resizes and (optionally) converts images the moment they are uploaded — all using the built-in PHP GD extension.
<h4>Features</h4>
<ul>
<li>JPEG compression — re-encodes JPEGs at a configurable quality level (default: 82). GD strips EXIF metadata automatically, further reducing file size.</li>
<li>PNG compression — applies lossless GD compression to PNG files.</li>
<li>PNG → JPEG conversion — converts opaque (non-transparent) PNGs to JPEG for significant space savings. Transparent PNGs are always kept as PNG.</li>
<li>Image resizing — scales down images that exceed a configurable maximum width or height while maintaining the original aspect ratio.</li>
<li>WebP generation — optionally saves a <code>.webp</code> sidecar file alongside every optimised image (requires GD compiled with WebP support).</li>
<li>Zero external dependencies — no API keys, no third-party services, no composer packages.</li>
<li>Graceful degradation — if GD is not available the plugin skips processing and logs a notice; uploads are never blocked.</li>
</ul>
<h4>Settings</h4>
Navigate to Settings → Image Optimiser to configure:
<ul>
<li>Enable / disable automatic optimisation on upload</li>
<li>JPEG quality (1–100, default 82)</li>
<li>Enable PNG → JPEG conversion</li>
<li>Enable WebP sidecar generation + WebP quality</li>
<li>Enable / disable resizing</li>
<li>Maximum width in pixels (default 1920)</li>
<li>Maximum height in pixels (default 1920)</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>PHP 7.4 or higher</li>
<li>PHP GD extension (enabled on virtually all shared hosting)</li>
<li>WordPress 5.9 or higher</li>
</ul>
