How do you encode your paper scans? (lemmy.ml)

I assume many of you host a DMS such as Paperless and use it to organise the dead trees you still receive in the snail mail for some reason in the year of the lord 2023.

How do you encode your scans? JPEG is pretty meh for text even at better quantisation levels ("dirty" artefacts everywhere) and PNGs are quite large. More modern formats don't go into a PDF, which means multiple pages aren't possible (at least not in Paperless).

@Atemu
Webp is much better, as long as your target reader(s) support it.

    Yes, as I said.

    As also mentioned in the post, I need a solution for multiple pages and an image (no matter what format) only represents a single page and WEBPs don't go into PDFs.

    @Atemu
    There's not really a magic bullet here. The current answer is to prepare a PDF outside of paperless and feed it in: https://github.com/paperless-ngx/paperless-ngx/discussions/367

    mpflanzer on that Issue is working on a file merging feature, but it's not ready yet.

    That's nice and all but does not answer how you'd create the PDF. Whether that happens outside paperless inside paperless does not make a difference. In the end, I need to create a PDF/A out of some images and the question on how to encode these images still remains.
