Java API to convert editable PDF to non-editable PDF

[Ruth Ambika]

Hi All,

I would like to know is there any Java API is available to convert editable PDF to non-editable PDF online. We have a client application where we need to fetch the editable PDF from backend and display as non-editable PDF in UI. Appreciate your help.

Thanks in advance!

iText can do this, somewhat like this:

PdfEncryptor.encrypt(
    new PdfReader("HelloWorldNotProtected.pdf"),
    new FileOutputStream("HelloWorldProtected.pdf"),
    null,
    "StrongPassword".getBytes(),
    PdfWriter.AllowPrinting,
    PdfWriter.STRENGTH128BITS);

This code is for iText 2, the API may have changed in iText 5, but should be similar. Instead of "PdfWriter.AllowPrinting" you could use a combination of other options (or none at all, meaning 0), depending on what you want the user to be able to do with the document.
