Dangerzone: Convert PDFs, documents, or images to a safe PDF
I don't have experience with Qubes in order to know what the files do, but this repo references two files in a qubes directory: e.g. https://github.com/freedomofpress/dangerzone/blob/v0.6.0/qub...

Ask HN: How can I security-sandbox email attachment opening?
start here: https://github.com/freedomofpress/dangerzone
i've never used it, but i've been meaning to check it out. at least it should give you a jumping off point for further investigation.
if that is insufficient, use proofpoint.
for archives that are tickling bugs, you have to use a similar technique. it's not enough to analyze them and send them on as-is. you have to unpack in a sandbox (which will be detectable, no 2 ways about it, but the question is will anyone expend enough effort to detect -- no, not for your use case, seeing as how you're asking the question at all), process with dangerzone or dangerzone-like tool, then re-archive it and let the user see only that new archive.

Ask HN: Why not cloud instead of Qubes “trusted PDFs” or Dangerzone?
I've read about the concept of "trusted PDFs" [1] from Qubes OS and the Dangerzone project [2].
I noticed people saying they use such tools to open applicant attachments in the context of employee hiring processes.
Isn't it simpler to just open these untrusted files in a cloud service like Google Drive or Microsoft Office online?

Downloading pdf’s & Javascript
This is exactly what DangerZone is built for. Takes ‘dangerous’ PDFs, converts them to images and back (via OCR) so there’s nothing potentially harmful inside. Does all the conversion inside docker containers so there’s little chance of a sandbox escape or network access

How can I implement this open-source tool as an API?
The source code for the CLI application is probably the best place to look for an example of how to use the internal parts of the code which perform the actual conversion: https://github.com/freedomofpress/dangerzone/blob/main/dangerzone/cli.py
