Why use PDFPremium.pro?
Many people "redact" PDFs by drawing black rectangles in an editor — but the text is still there underneath, and anyone can copy-paste it out. Real redaction tools that permanently remove content are usually paid features in premium PDF suites. This tool does it properly and free: you draw boxes over account numbers, signatures, addresses, or any sensitive text, and the pages are rebuilt as flat images with the boxes burned in. The original text is gone from the file — not hidden, removed. It works page by page on multi-page documents, entirely in your browser, so confidential agreements and statements never leave your device. As with every tool on this site, processing happens entirely inside your browser — no uploads, no sign-ups, no watermarks.
Frequently asked questions
Is the hidden text really removed?
Yes — pages are rebuilt as flat images after the black boxes are burned in, so the text underneath no longer exists in the file. Copy-paste and text extraction cannot recover it.
Is this tool really free?
Yes — completely free with no hidden limits, watermarks, or sign-up. The site is supported by light advertising.
Are my files uploaded to a server?
No. Everything runs inside your browser using JavaScript — your files never leave your device, ever.
