Streaming Data with PyPDF2
In some cases you might want to avoid saving things explicitly as a file to disk, e.g. when you want to store the PDF in a database or AWS S3.
PyPDF2 supports streaming data to a file-like object and here is how.
from io import BytesIO # Prepare example with open("example.pdf", "rb") as fh: bytes_stream = BytesIO(fh.read()) # Read from bytes_stream reader = PdfReader(bytes_stream) # Write to bytes_stream writer = PdfWriter() with BytesIO() as bytes_stream: writer.write(bytes_stream)
