Redact PDF: Arthize vs Smallpdf
Updated July 2026
To redact a PDF, Arthize offers a free, private redact pdf with no watermark — a focused alternative to Smallpdf. 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.
Arthize's redact pdf vs Smallpdf
Smallpdf is a popular freemium web-based PDF toolkit. Smallpdf offers a clean set of web tools on a freemium model with usage limits on the free tier.
Arthize's approach: 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.
- Files are processed inside your private Arthize workspace and deleted after the job — never sold or used to train models.
- The free plan never adds a watermark to your output.
- Transparent pricing: free forever, Pro from $6/mo or $48/yr, and a one-time $149 lifetime option.
- A one-time lifetime option instead of only monthly billing.
How to redact a PDF with Arthize
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.
