pdfsam VS pdf-lib

I find pdfsam to be the perfect offline tool for me on Windows.

And it's open source as well: https://github.com/torakiki/pdfsam

That might be fit for your purpose PDFSam

use pdfsam.org to split the pdf into individual sheets fyi

PDFsam - merge, split, extract pages, rotate and mix your PDF files

I have used tools, like PDFsam, to insert, delete, reorder, and rotate pages in existing PDFs. It's a great tool, but it's not a complete PDF editor.

writePdf: used for writing the final completed PDF after receiving the response from the Claude 3 Opus API, this uses the PDF-lib library to manipulate and modify the final file.

I stand on the shoulders of giants, namely PDF-lib, PDF-js and React-beautiful-DND – everything else is pretty much custom code.

How one can use a library such as PDF-Lib (npm, website) that:
