Does cropping reduce photo resolution or quality?

No, cropping preserves full source pixel resolution within the crop boundary and outputs a lossless 100% sharp PNG image.

Are my images uploaded to any server during cropping?

No, all image processing and crop rendering happen 100% locally inside your web browser using JavaScript HTML5 Canvas.
