What examples should you start with?
Standard page
MediaBox [0 0 612 792]8.5 × 11 in at 72 points per inchRotated page
Rotate 90Rotation is shown separately from the page boxesHow does it work?
pdf-lib loads the PDF in browser memory and reads the page dictionary values through its page API.
Missing optional boxes fall back to the PDF box defined by the library, so the displayed value is explicit and comparable across pages.
What are the edge cases and limits?
- PDF size is limited to 25 MB and page count to 100 pages.
- A rotation entry changes presentation orientation; it does not rewrite the coordinates stored in the page boxes.
- Encrypted, damaged, or unsupported PDFs may fail before geometry can be read.
