Is there a limit on file count or size?

There is no hard limit, but very large PDFs may be slow to process depending on your device's memory. All files must fit in the browser's available RAM simultaneously.

Does it preserve fonts and images?

Yes. pdf-lib copies pages with their full content including embedded fonts, images, and annotations.
