Trusted by 1,000+ professionals · No credit card required
Looking for a Nitro Redact alternative? "Nitro Redact" usually means one of two things: Nitro Pro's built-in manual Redaction Tool, or Nitro Smart Redact, Nitro's separate AI-powered add-on (€168–€224/user/year, capped at 250–500 documents per year, with documents uploaded and temporarily stored in Nitro's cloud for processing). PDF Redaction offers the same AI-powered automatic PII detection with no document caps, zero-file-storage, a genuine free tier, and pay-per-page pricing — plus a Linux, Windows desktop app, n8n integration, Obsidian plugin.
Quick answer: PDF Redaction is the best Nitro Redact alternative for teams that want AI-powered automatic PII detection without Nitro Smart Redact's annual per-seat pricing, 250–500 document/year cap, or cloud upload requirement. It detects the same 30+ PII categories, adds a genuine
0/month free tier (100 pages/month), pay-per-page pricing from0.05/page, and a zero-file-storage privacy mode — with no annual contract required.Last updated: September 2026.
What Is Nitro Redact?
"Nitro Redact" isn't a single product — it's two different tools inside Nitro's PDF suite:
- Nitro Pro's Redaction Tool — a manual black-out/white-out tool included with Nitro PDF Standard/Plus (from ~€14/user/month). You select each piece of sensitive text yourself; there's no automatic PII detection.
- Nitro Smart Redact — Nitro's AI-powered redaction add-on, priced separately at €168–€224/user/year and capped at 250–500 documents/year (5,000+ on Enterprise). It uses NLP to detect 30+ PII categories, but documents are uploaded and temporarily stored in the cloud during processing.
PDF Redaction combines both: AI-powered automatic detection and zero-file-storage privacy, in every plan — including the free tier.
