PDF Editor
Free Online PDF Editor with True Redaction & Annotations
Edit, annotate, and sanitize your PDF documents directly in your browser with complete privacy. Our editor offers True Redaction that permanently burns blackouts into pixels, stripping underlying vector text streams so sensitive data can never be selected, copied, or extracted.
Features include a semi-transparent yellow highlighter pen with blend modes, custom digital signatures, text box annotations, and a drag-and-drop page organizer — running 100% client-side with zero data uploaded to any server.
- True Redaction: Permanently burns blackouts into pixels and strips underlying text streams
- Highlighter Pen: Semi-transparent yellow marker overlay that keeps text underneath clear and legible
- Sign Documents: Draw or type your signature and place it anywhere
- Add Text & Annotations: Insert customizable text boxes with custom fonts
- 100% Client-Side Privacy: All rendering and sanitization happens locally in your browser
Why True Redaction & Local Editing Matters
Most free PDF editors only draw a superficial black rectangle over text — leaving the original words underneath fully selectable, copyable, and searchable via Ctrl+F. Our True Redaction engine rasterizes and permanently overwrites redacted pages at high resolution, completely destroying underlying text and vector objects. Combined with 100% client-side processing, your confidential records, contracts, and tax forms are protected from leaks.

💡 Pro Tips
- Use "Redact" whenever hiding sensitive personal info (SSNs, account numbers, names) — our True Redaction physically strips the text stream so it cannot be copied or indexed.
- Use "Highlight" to emphasize key clauses; the yellow marker draws with multiply blending so the underlying text remains crisp and readable.
- If your PDF is password-protected, the editor unlocks it locally in memory without transmitting your password anywhere.
