I am wondering if there is an easy way to combine multiple png images into a single pdf in python. I want each image to be a single page in the pdf. Is pypdf the best librar

Answer 1

I've got the same problem.

So I've created python function to unite multiple pictures in one pdf. Code is available at my github page on https://github.com/wizard1989/Unite-multiple-pictures-into-pdf. It uses "reportlab".

Code is based on answers from the following links:
Create PDF from a list of images

How can I convert all JPG files in a folder to PDFs and combine them? https://www.blog.pythonlibrary.org/2012/01/07/reportlab-converting-hundreds-of-images-into-pdfs/

Here is example of how to unite images into pdf.

We have folder "D:\pictures" with pictures of types png and jpg. We want to create file pdf_with_pictures.pdf out of them and save it in the same folder.

outputPdfName = "pdf_with_pictures"
pathToSavePdfTo = "D:\\pictures"
pathToPictures = "D:\\pictures"
splitType = "none"
numberOfEntitiesInOnePdf = 1
listWithImagesExtensions = ["png", "jpg"]
picturesAreInRootFolder = True
nameOfPart = "volume"

unite_pictures_into_pdf(outputPdfName, pathToSavePdfTo, pathToPictures, splitType, numberOfEntitiesInOnePdf, listWithImagesExtensions, picturesAreInRootFolder, nameOfPart)
