Question 1

How do I merge multiple PDFs using pikepdf?

Accepted Answer

Use Pdf.new() to create a blank PDF, then extend its pages with pages from source PDFs in a loop, as shown in the README example. This allows lossless merging with automatic repair.

Question 2

pikepdf vs pypdf: which is better for editing PDFs?

Accepted Answer

pikepdf excels at repair and low-level manipulation thanks to qpdf, making it ideal for damaged files or encrypted PDFs. pypdf is pure Python and better for simple, dependency-light tasks like basic page operations.

Question 3

Can pikepdf extract text from PDFs?

Accepted Answer

No, pikepdf focuses on structural manipulation and does not support text extraction. For that, use dedicated libraries like pdfminer.six or pdfplumber, which are mentioned in the README as alternatives.

Question 4

Is pikepdf good for editing metadata in PDFs?

Accepted Answer

Yes, it provides full read/write support for XMP metadata and DocumentInfo with automatic synchronization, allowing programmatic updates while preserving standards compliance.

Question 5

How to handle password-protected PDFs with pikepdf?

Accepted Answer

Pass the password parameter when opening a PDF, and use the encryption setting when saving to add or remove protection, supporting AES-256, AES-128, and RC4 as detailed in the README examples.

Question 6

Does pikepdf support creating PDF/A files?

Accepted Answer

It can modify existing PDFs without breaking PDF/A conformance, but check the documentation for specific guidelines, as it's more about preservation than generation from scratch.
