Features

Presets

People who own, design, or develop websites are constantly looking for efficient ways to boost performance without getting down in tweaking every single setting. This is precisely where the “Presets” feature of the PageSpeed Ninja comes in.

PageSpeed Ninja offers five different presets, each tailored to specific optimization needs:
– Optimal: suitable for the majority of websites,
– Safe: prioritizes compatibility (only a minimal subset of optimizations is enabled),
– Compact: focuses on saving disk space (image optimization and convert to WebP are disabled),
– Ultra: aims for maximum optimization (but may be incompatible with some themes and plugins),
– Experimental: reserved for testing new, possibly less stable features.

PageSpeed Ninja Settings Groups

PageSpeed Ninja organizes its settings into groups aligned with the Google PageSpeed Insight categories. Using the data from the Google PageSpeed Insight speed analysis, the plugin categorizes the settings groups into three distinct classes: Should Fix, Consider Fixing, and Passed.

Within the General settings, users can easily enable or disable each settings group (specific settings depend on the preset selected), and the Advanced settings page offers fine-tuning all settings according to specific preferences.
