• Multiple JPEG to PDF

    From Heron@21:1/5 to All on Wed Feb 2 18:26:37 2022
    Teacher made multiple page math JPGs of his copious class notes.
    I cleaned them up as they were terrible grayscale smudged photographs.
    Now they're clean & only black & white all of the same size & aspect ratio.
    I even had to straighten them out and get rid of pure black on edges.

    Now they're beautiful.
    But they're still JPEGs.
    Lots of them.

    They have a naming convention though, by chapter, topic, and page.

    But how can I give it back other than a zip file with hundreds of JPEGs?
    Is there the concept of a multiple page JPG that all people can read?
    Probably not.

    Whatever I give them has to be usable by many others.
    I think TIFF would be too esoteric for most.

    Maybe PDF?
    Is there a multiple JPEG to multi-page single PDF converter for example?

    Open them in a viewer, then print to PDF. See https://www.alphr.com/create-pdf-windows-10/ for Windows.
    On MacOS you can open them all at the same time in Preview, then print to PDF. --

    There are various tools for converting multiple jpegs into a single PDF.
    Try a web search for

    On GNU/Linux, there is usually img2pdf than can create a pdf from
    multiple jpeg (one jpeg per page). Follow that up with ocrmypdf, if you
    want OCR.

    Yes, it's called PDF. It's a container that (among lots of other things)
    can be used to store multiple images.
