PyPDF2 VS pikepdf

use PDF::FromImage;...my $pdf = PDF::FromImage->new;$pdf->load_images(@allPagesDir);$pdf->write_file($bookName . '.pdf'); I need to do something very similar to this, but in Python. I know the pyPdf module, but I would like something simple.

pikepdf – A Python library for reading and writing PDF, powered by qpdf

Not off the shelf but here are some tools. I have no experience with them.

Wolf binarization - I think it makes the text more clear before OCR.

This thing OCRs the pdf using Tesseract OCR

Two other pdf tools

i recently transitioned a large PDF processing pipeline[1] away from PyPDF3 to use the pikepdf[2] library instead. pikepdf is based on the C++ `qpdf` library, and this switch has cut the necessary special-case manual checking + error handling in half compared to pypdf for these sorts of tasks.

[1]: i'm helping out with the CV Open Access archive, https://openaccess.thecvf.com/menu. broadly, our pipeline needs to ingest tons of author-provided PDFs of varying quality and output a canonical PDF with corrected page numbers, proper metadata, and a banner stamped on the first page. it's a lot of work, and it's not uncommon for pypdf to simply fail for slightly invalid input or give garbled results. this isn't optimal since we can't review 2,000 papers per conference release lol. pypdf has been nice, but pikepdf has handled everything i've thrown at it.
