Redact PDF for authors
Updated July 2026
Arthize lets authors and self-publishers redact a PDF in a private workspace — free, with no watermark. Redacting a PDF permanently removes the underlying text and images under a black box — not just covering them — so hidden data can't be recovered.
Why authors redact a PDF
An author merges manuscript chapters into one file, resizes the pages to the print trim size, and exports a clean, watermark-free PDF for the printer.
Built for manuscripts. Whether it's manuscripts, proofs, cover files, Arthize's redact pdf keeps the work inside your private workspace. Unpublished manuscripts are valuable IP; private processing keeps them off public servers.
What matters when you redact a PDF
Real redaction deletes the underlying content; a black rectangle alone can be removed to reveal the text.
Copying text from under a fake redaction box exposes the hidden data — a common leak.
Redaction should also clear document metadata that can leak names and edit history.
