PDF Redaction — Frequently asked questions
Is PDF Redaction free for teachers?
Yes. Free for every classroom — no licence, no procurement request. There is no signup, no trial and no watermark on your files.
What kind of files can teachers use PDF Redaction for?
PDF Redaction works with the documents teachers handle every day — lesson plans, worksheets, exam papers, student handouts, grading rubrics and permission slips. A common case: Merging a week of worksheets and answer keys into one printable packet for the class.
Is the redacted text truly removed?
Yes. Redaction removes the underlying content — not just a black box you can copy behind.
Can redacted information be recovered?
No. Once redacted and downloaded, the removed content cannot be retrieved from the file.
How do I permanently delete sensitive info from a PDF?
Mark the sensitive text or area, apply redaction, and download a file with that information fully removed — not just hidden.
What is the difference between redaction and a black box?
A black box can be removed or copied behind. Redaction here deletes the underlying data so no trace remains.
Can I use it to hide ID numbers or bank accounts?
Yes. Ideal for removing ID numbers, bank accounts and names before sharing contracts and official documents.
Does the rest of the document stay intact?
Yes. Only what you marked is removed; the rest of the content and formatting stays unchanged.
