PDF Redaction for Students
It is 11:50 PM, the submission closes at midnight, and the portal rejects your 40 MB project file. If you work as one of the students, you have been there. Confileo's PDF Redaction tool permanently removes sensitive text and information from a PDF — free, in your browser, with your files deleted automatically the moment you are done.

PDF Redaction — Frequently asked questions
Is PDF Redaction free for students?
Yes. No software to install — works on lab computers, Chromebooks and phones. There is no signup, no trial and no watermark on your files.
What kind of files can students use PDF Redaction for?
PDF Redaction works with the documents students handle every day — lecture notes, research papers, assignment PDFs, scanned textbooks, thesis chapters and study guides. A common case: Submitting assignments before a deadline when the upload portal only accepts one PDF under a strict size limit.
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.
