Redact PDF Online
Draw rectangles over sensitive content to permanently remove it. Unlike simple black boxes, our redaction physically removes the text underneath — it cannot be copied or recovered.

Frequently Asked Questions
Does redaction actually remove the text, or just cover it?+
Our redaction truly removes the text. Redacted pages are flattened to images at high resolution (216 DPI), so the original text data is physically destroyed. The blacked-out text cannot be selected, copied, or recovered by any means.
Is it safe to redact sensitive documents online?+
Yes. Your PDF never leaves your device. All processing — including the page flattening that destroys redacted text — happens entirely in your browser. No server ever sees your document.
Will redaction affect the quality of my PDF?+
Pages with redactions are converted to high-quality JPEG images (216 DPI, 92% quality). Pages without redactions are preserved in their original format with full text and vector quality.
Can I redact multiple areas across different pages?+
Yes. Draw as many redaction rectangles as you need on any page. Navigate between pages and add regions before applying the redaction in one step.
