    PDF or JPEG Document Exchange - Which is Better?


    PVA - Jim

    JPEG

    PROs
    • Secure- The receiver can’t “take” your geometry from the image.

    CONs
    • A jpeg file has a fixed resolution and therefore looks different on every computer. Importing one into a CAD program produces different size results depending on the program settings.
    • Many email servers "scrub" jpeg images looking for viruses, and the process can scramble some jpegs, or leave you with only the postage-stamp preview in many cases.

    PDF

    PROs
    • In most cases, when you send someone a PDF, it will allows look the same regardless of application or operating system.

    CONs
    • Data is unsecure. The PDF can be imported into a CAD program and the vector data can easily be “harvested”


    What is the best choice? Do both.

    • In Vectorworks, export your document as a PDF.
    • Convert the PDF to JPEG and lock in the resolution. Around 200 dots per inch is normally sufficient.
    • Convert the newly created JPEG back to a PDF. Now you have all the security of a PDF, without the “harvestable” vector and text data.
