How to open a PDF in Python using only a byte string or Base64? (Not using directories)

  • 772

Hello, good, I have the following code in Python that prints the number of pages and the data of a PDF, however, this only works if I call the PDF with a directory on my PC. What I want it to do is open the PDF for me using only the Bytes or Base64 string I provide without having to write a new PDF on my pc .

PDFBase64="JVBERi0xLjUNCiW1tbW1..."
Decodificado=base64.b64decode(PDFBase64)
documento=fitz.open(Decodificado)

print("Número de páginas: ",documento.page_count)
print("Datos: ",documento.metadata)```
python

    Documentation I relied on: https://pymupdf.readthedocs.io/en/latest/document.html#Document

    To tell pymupdf that we want to load the file from memory, we use the stream argument, whose documentation translated by me and google translate says:

    stream (bytes, bytearray, BytesIO) : An area of ​​memory that contains a supported document. If it is not a PDF, its type must be specified by filename or filetype.

    Which, as we can see, accepts objects of type byte. We don't even need a stream.

    In this sample code, we load a pdf from the internet (in byte form) and save it to disk, thus proving that the content was successfully retrieved (requires the requests library)

    import requests
import fitz

pdf_url = "https://serviciosweb.afip.gob.ar/genericos/formularios/pdf/interactivos/f460f.pdf"

pdfbytes = requests.get(pdf_url).content

fitz.open(stream=pdfbytes).save("prueba.pdf")

    Final note: Sometimes the documentation answers our questions. It's always a good idea to review it before asking someone else. You could find the answer much more quickly and autonomously. To give you an idea of ​​how useful it is, I never used this module and I was able to give you an answer c:
