Can Python Perform PDF File Merging and Manipulation Using PyPDF?

Can Python Merge PDF Files?

Python provides extensive capabilities for manipulating PDF documents, including merging. The versatilepypdf library offers convenient tools for combining multiple PDF files.

File Concatenation

Using the append method of the PdfMerger class, concatenate files sequentially:

<code class="python">from pypdf import PdfMerger

pdfs = ['file1.pdf', 'file2.pdf', 'file3.pdf', 'file4.pdf']

merger = PdfMerger()

for pdf in pdfs:
    merger.append(pdf)

merger.write("result.pdf")
merger.close()</code>

Fine-Grained Merging

For more control, use the merge method to insert pages at specific locations:

<code class="python">merger.merge(2, pdf)</code>

Page Ranges

Specify page ranges to append from a particular file using the pages keyword argument:

<code class="python">merger.append(pdf, pages=(0, 3))    # first 3 pages
merger.append(pdf, pages=(0, 6, 2)) # pages 1,3, 5</code>

Handling Empty Pages

To exclude an empty page present in each PDF, use PyMuPdf's insert_pdf method:

<code class="python">import fitz

result = fitz.open()

for pdf in ['file1.pdf', 'file2.pdf', 'file3.pdf']:
    with fitz.open(pdf) as mfile:
        for page in mfile.pages:
            # Skip empty pages
            if page.get_text('blocks') != '':
                result.insert_page(len(result), page)

result.save("merged_without_empty.pdf")</code>
