Page numbers are 1-based; every segment produces its own PDF and the output joins their base64 with newlines.
Frequently asked questions
How do I write page ranges?
Use 1-3 for a range and 3 for a single page; each comma-separated segment becomes one PDF, and semicolons or newlines also separate segments.
What about out-of-range pages?
It fails with invalid-input instead of emitting an empty document; 9-20 on a six-page file is rejected.
Is the content re-compressed?
No. Only the page tree and object table are rebuilt; content streams are copied as they are.
Can encrypted PDFs be split?
No. Encryption is detected and reported as encrypted; decrypt the file first.
