Frequently Asked Question
original images remain unchanged

The retina factor controls at which pixel density images are displayed for high-resolution screens. A higher value makes images appear sharper on retina displays but also increases file size.

The neo Optimize plugin uses a default retina factor of 1.5x to improve the rendering of small text, icons and image details on retina displays. In the Pro version you can set the retina factor individually and compare it directly in the preview.

Under normal operation it is not necessary to clear the neo Optimize cache. The clear cache button can be helpful if you want to remove old image variants after many tests or tidy up after major changes to image sizes in the page builder. Afterwards the optimized images will be automatically regenerated as soon as they are needed again on the frontend.

If you change image quality, the retina factor or other optimization settings, neo Optimize will automatically create new optimized images. When an image is deleted from the WordPress media library, the related cache files are automatically removed. Even optimized images that were renamed with neo Rename are automatically cleaned up.

The Clear Cache button is therefore intended mainly as a reset and cleanup function.

If a graphic was created with neo Draw, neo Optimize can automatically optimize it when serving on the frontend. Unnecessary editor data for display is removed and embedded raster graphics are converted to the efficient WebP format.

The original neoDraw file remains fully intact and editable. Visitors receive a leaner, faster version in the frontend while you can continue to work with the editable original drawing in the backend.

The neo Optimize plugin is a WordPress image optimization plugin. It automatically reduces images to the actually needed display size and converts image files to the efficient WebP format. This results in faster image loading and a more performant website, which positively affects SEO ranking.

What’s special about neo Optimize is that the original images remain unchanged and the optimized versions are stored in a separate cache directory. The plugin also works without credit packages because it optimizes images directly on your own server for free.

Yes. You can override the automatically determined optimization per image using HTML attributes. This is especially useful when an image is displayed differently in a page builder than it can be automatically detected. Examples:

<img data-neo-optimize--width="320px" src="...">
<img data-neo-optimize--height="180px" src="...">
<img data-neo-optimize--quality="75" src="...">

With the Pro version you can additionally control the retina factor and the algorithm used per image:

<img data-neo-optimize--retina="150" src="...">
<img data-neo-optimize--algorithm="imagick" src="...">

The neo Optimize plugin processes your images directly on your own server. Local server functions like Imagick or PHP GD are used for image optimization. That means you don’t need credit packages for external image services or additional cloud processing.

This makes the optimization free, privacy-friendly and independent from external providers.

Yes, neo Optimize works with all common page builders. These include Bricks, Elementor, Divi, Beaver, Oxygen, Breakdance and Gutenberg.

The configured image sizes can be automatically read by neo Optimize and used as the basis for optimization. This ensures the image is adapted as closely as possible to the actual display size and cached for quick serving.

The image optimization of neo Optimize supports many common raster formats, including JPG, JPEG, PNG, GIF, WebP, AVIF, BMP, HEIC, HEIF, TIFF and many other formats, provided they can be processed on your server by Imagick or PHP GD.

Raster images are optimized, scaled, and stored in the cache as WebP files. Additionally, neo Optimize can also optimize special neo Draw SVG graphics for frontend output.

For most websites we recommend a WebP quality of 75%. The WebP format is very efficient, so even lower quality settings often still look very good and produce significantly smaller files.

In the settings of neo Optimize you can conveniently choose the quality and directly evaluate it via a preview with file size. This way you quickly find the right balance between high image quality and fast loading times.
