Workaholic PDFToolBoxīy the use of this software you can insert text watermark only to a PDF file. You need to install Java on your computer to run this software. It is a simple application with portable utility to add watermark to a PDF document. In this software you get the option to select color of your choice to watermark the PDF file. Target_files.append(os.path.join(path, name))Įxtracted_files = fetch_all_files('./parent_folder')įinally, you use the two functions declaring.You can insert text watermark to a single PDF document at a time by the use of this application. Merge_pdf('./final.pdf', extracted_files)Īnd this function to get all the files recursively from a parent folder: import osįor path, subdirs, files in os.walk(parent_folder): # pass the path of the output final file.pdf and the list of pathsĭef merge_pdf(out_path: str, extracted_files: list ): You can use PdfFileMerger from the PyPDF2 module.įor example, to merge multiple PDF files from a list of paths you can use the following function: from PyPDF2 import PdfFileMerger Merger.write(file_folder + "Economists-1.pdf") Root, dirs, files = next(os.walk(file_folder))įor path, subdirs, files in os.walk(root): Please use the following:- from PyPDF2 import PdfFileMerger, PdfFileReader Similarly: from pyPdf import PdfFileWriter, PdfFileReaderĪppend_pdf(PdfFileReader(file("C:\\sample.pdf","rb")),output)Īppend_pdf(PdfFileReader(file("c:\\sample1.pdf","rb")),output)Īppend_pdf(PdfFileReader(file("c:\\sample2.pdf","rb")),output)Īppend_pdf(PdfFileReader(file("c:\\sample3.pdf","rb")),output) PyPDF2 start = time.time()įormatted_name = f'Summary_Invoice_.pdf' Pdfrw is the fastest library for combining pdfs out of the 3 I tested. (Disclaimer: I ran this function within Flask, your mileage may vary) TL DR Here's a time comparison for the most common answers for my specific use case: combining a list of 5 large single-page pdf files. Print("Start writing '%s'" % output_filename) The following example merges all files in one folder to a single new PDF file: #!/usr/bin/env pythonįor pdffile in glob(path + os.sep + '*.pdf'):ĭocument = PdfFileReader(open(pdffile, 'rb')) Is it possible, using Python, to merge seperate PDF files? Input_streams.append(open(input_file, 'rb'))įor reader in map(PdfFileReader, input_streams): # the data isn't read from the input files until the write # First open all the files, then produce the output file, and #!/usr/bin/env pythonįrom PyPDF2 import PdfFileReader, PdfFileWriterįrom pyPdf import PdfFileReader, PdfFileWriter Here's a sample program that works with both versions. Note: in older versions of PyMuPDF insert_pdf was insertPDFĪ Pure-Python library built as a PDF toolkit. With plenty of options, detailed in the projects wiki. Merging is equally simple.įrom command line: python -m fitz join -o result.pdf file1.pdf file2.pdf file3.pdfįor pdf in : The pypdf documentation also includes some example code demonstrating merging.Īnother library perhaps worth a look is PyMuPdf. You can potentially avoid the need to write code altogether. You might also want to look at the pdfly cat command provided by the pypdf developers. It's a shame that PdfMerger isn't implemented as a context manager, so we can use the with keyword, avoid the explicit close call and get some easy exception safety. This ensures all files are closed (input and output) in a timely manner. Note: also that to avoid files being left open, the PdfMergers close method should be called when the merged file has been written. If you specify an invalid range you will get an Inde圎rror. merger.append(pdf, pages=(0, 3)) # first 3 pages If you wish to control which pages are appended from a particular file, you can use the pages keyword argument of append and merge, passing a tuple in the form (start, stop) (like the regular range function).Į.g. Here we insert the whole PDF into the output but at page 2. The append method can be thought of as a merge where the insertion point is the end of the file. If you want more fine grained control of merging there is a merge method of the PdfMerger, which allows you to specify an insertion point in the output file, meaning you can insert the pages anywhere in the file. You can pass file handles instead file paths if you want. You can simply concatenate files by using the append method.
