PDF for teachers
For the worksheet you are making tonight, and for the material you sell.
Two different jobs
The first is making things: worksheets, quizzes, answer keys, rubrics, permission slips, reading lists. Usually assembled from several files, often needing a fillable field or two, and always needed sooner than expected.
The second is selling them. Hundreds of thousands of teachers sell material they made, and the concern there is different: a PDF you sell can be copied, edited and passed on the day after someone buys it.
What helps is real encryption rather than a setting, flattening so the content cannot be edited back out, and a watermark or stamp so a leaked copy still points home. All three are here.
The tools for it
- Protect PDFSet a password so only the right people can open it.
- Flatten PDFBake form fields into the page so no one can change them.
- Watermark PDFStamp text across every page — angle and opacity are yours.
- Add stamp to PDFStamp an approval, date or logo — pick the corner and opacity.
- Merge PDFCombine several PDFs into one, in the order you want.
- Create fillable PDFDraw boxes where people should type, and get a PDF they can fill in.
What this does not do
No PDF protection stops a determined person. Someone can photograph a screen, and any encryption that lets a buyer read the file also lets a buyer keep it. What protection does is stop casual copying and make a leak traceable — that is real, but it is not the same as making a file uncopyable, and anyone who tells you otherwise is selling something.
We also do not host or sell your material. Making the package is where our part ends.
In every case above, the document is processed without ever being transmitted. Nothing is uploaded, which for confidential filings, student records, unpublished manuscripts and salary data is not a convenience but the point.
