## Global Preferences

Configure global settings for your Booklore instance, including cover image handling, search preferences, and file upload limits.

### Book Cover Image

Regenerate Covers

Regenerates cover images for all books from the embedded covers in the file.

Vertical Cover Cropping

Automatically crop extremely tall images (like web comics) from the top to create usable cover thumbnails.

Horizontal Cover Cropping

Automatically crop extremely wide images from the left to create usable cover thumbnails.

Aspect Ratio Threshold: {{ coverCroppingSettings.aspectRatioThreshold }}

Images with aspect ratios exceeding this threshold will be cropped. A value of 2.5 means images more than 2.5x taller (or wider) than normal will be cropped.

Smart Cropping

Skip uniform colour regions when determining where to crop. Focuses the cover image on the most relevant content.
