How to Merge two pages from a pdf file as one page
Question:
I have a pdf in which there are total 6 pages of images.I want to merge page 1 and 2 as a single pdf and so on for 3 to 6 pages.
I splitted all 6 pages of pdf as individual pdf.
import os
from PyPDF2 import PdfFileReader, PdfFileWriter
def pdf_splitter(path):
fname = os.path.splitext(os.path.basename(path))[0]
pdf = PdfFileReader(path)
for page in range(pdf.getNumPages()):
pdf_writer = PdfFileWriter()
pdf_writer.addPage(pdf.getPage(page))
output_filename = '{}_page_{}.pdf'.format(
fname, page+1)
with open(output_filename, 'wb') as out:
pdf_writer.write(out)
print('Created: {}'.format(output_filename))
if name == ‘main‘:
path = ‘D:TasksSamplesfw9.pdf’
pdf_splitter(path)
I want to know how to merge page 1 and 2 of fw9 as single pdf file which contains only 1 page which have half page as page 1 of fw9 pdf file and another half as page 2 of fw9 pdf.I have to do this for all 6 pages as 1-2 as 1 pdf with 1 page ,3-4 page as another pdf which has only 1 page with both on the same page and so on.Kindly help if any one have any idea on how to do so.
Answers:
The library pyPDF2 has also a PdfFileMerger object, that should do exactly what you want.
As from the example here you can just create a PdfFileMerger, read two pages and put them into one single file.
I changed your script slightly to create also files with pages 0-1, 2-3, 4-5 ecc.. (of course page 0 is the first page but python numbering starts from 0)
import os
from PyPDF2 import PdfFileReader, PdfFileWriter, PdfFileMerger
def pdf_splitter(path):
fname = os.path.splitext(os.path.basename(path))[0]
pdf = PdfFileReader(path)
input_paths = []
for page in range(pdf.getNumPages()):
pdf_writer = PdfFileWriter()
pdf_writer.addPage(pdf.getPage(page))
output_filename = '{}_page_{}.pdf'.format(fname, page+1)
input_paths.append(output_filename)
with open(output_filename, 'wb') as out:
pdf_writer.write(out)
print('Created: {}'.format(output_filename))
# every 2 pages!
# Change the two if you need every other number of pages!
if page % 2 == 1:
pdf_merger = PdfFileMerger() #create pdfilemerger
for path in input_paths:
pdf_merger.append(path) #read the single pages
# we call it pages_N-1_N, so first would be pages_0_1!
output_path = '{}_pages_{}_{}.pdf'.format(fname, page-1, page)
with open(output_path, 'wb') as fileobj:
pdf_merger.write(fileobj) # write the two pages pdf!
input_paths = []
if __name__ == '__main__':
path = 'D:TasksSamplesfw9.pdf'
pdf_splitter(path)
Is this what you wanted?
This will first create single pdf for each page and then combine them 2 to 2. Creating the single pdf could also be skipped, but I was not sure whether you want it or not.
from PyPDF2 import PdfFileReader, PdfFileWriter
from PyPDF2 import PageObject
#Open the files that have to be merged
pdf1File = open('document.pdf', 'rb')
#Read the files that you have opened
pdf1Reader = PdfFileReader(pdf1File)
#Make a list of all pages
pages = []
for pageNum in range(pdf1Reader.numPages):
pageObj = pdf1Reader.getPage(pageNum)
pages.append(pageObj)
#Calculate width and height for final output page
width = pages[0].mediaBox.getWidth() * 6
height = pages[0].mediaBox.getHeight() + 100
#Create blank page to merge all pages in one page
merged_page = PageObject.createBlankPage(None, width, height)
#Loop through all pages and merge / add them to blank page
x = 0
for page in pages:
merged_page.mergeScaledTranslatedPage(page, 1, x, 10)
x = float(x) + float(page.mediaBox.getWidth())
#Create final file with one page
writer = PdfFileWriter()
writer.addPage(merged_page)
with open('out.pdf', 'wb') as f:
writer.write(f)
I wanted to merge 6 files / page so I have used 6 as a multiplier for page width.
this is the answer of how to merge two pages to one page in vertical way

pages = []
for pageNum in range(pdf1Reader.numPages):
pageObj = pdf1Reader.getPage(pageNum)
pages.append(pageObj)
#Calculate width and height for final output page
width = pages[1].mediaBox.getWidth() * 2
height = pages[1].mediaBox.getHeight()
#Create blank page to merge all pages in one page
merged_page = PageObject.createBlankPage(None, width, height)
writer = PdfFileWriter()
#Loop through all pages and merge / add them to blank page
y =0
merged_page = PageObject.createBlankPage(None, width, height)
for page in range(len(pages)):
y+=1
if y%2!=0:

@al3rab sword, when I try your code, I get the output but I am expecting odd numbered pages(1,3,5..) on left side and even numbered pages(2,4,6…) on right side.
Currently this is not happening.
