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)
