Answer 1

Spire.PDF for Python module can be used to convert PDF to PDF/A-3a or PDF/A-3b.

Here is a simple example:

from spire.pdf.common import *
from spire.pdf import *

# Specify the input file path and output folder
inputFile = "Sample.pdf"
outputFolder = "Output/"

# Create an object of the PdfStandardsConverter class
converter = PdfStandardsConverter(inputFile)

# Convert the input file to Pdf/A-3a
converter.ToPdfA3A(outputFolder + "ToPdfA3A.pdf")

# Convert the input file to Pdf/A-3b
converter.ToPdfA3B(outputFolder + "ToPdfA3B.pdf")

Here is the resultant file:
