Free PDF Redaction Tool

AI-powered PII detection. Permanent pixel-burn redaction. Documents never leave your browser. Unlimited use, forever free.

No credit card · No trial period · No limits on documents

What You Get Free

🤖 AI-Powered Detection

Automatically finds names, SSNs, addresses, phone numbers, emails, dates, and financial account numbers. No manual selection needed.

🔒 Permanent Redaction

Pixel-burn technology destroys sensitive data at the pixel level. Not a black box — the data is permanently gone from the output file.

🌐 Browser-Based

Documents stay in your browser. AI detection uses bank-grade TLS 1.3 encryption with zero data retention. No complete files ever uploaded.

♾️ Unlimited Documents

No daily limits. No page caps. No throttling. Process as many documents as you need, as often as you need.

📄 PDFs and Images

Supports PDF documents and image files (PNG, JPG). Drag and drop — it just works.

⚡ 30-Second Workflow

Drop file → AI detects PII → Review → Apply → Download. A 12-page document takes under a minute.

What's the catch? The free tier adds a small SafeRedact watermark to the bottom of redacted documents. Everything else — AI detection, permanent redaction, unlimited use — is identical to paid plans. Remove the watermark with a $5 day pass, $99/year, or $99/year.

Free Redaction Tools Compared

Tool AI Detection Permanent No Upload Free Limit Catch

Xodo ✗ (cloud) 5 actions/day Manual selection, cloud upload

iLovePDF ✗ (masking only) ✗ (cloud) Limited Not true redaction — visual masking only

SafeRedact is the only free tool with AI-powered detection. Every other free option requires you to manually find and select every piece of sensitive information — which means you'll miss things, especially across long documents.

How It Works

Step 1: Go to saferedact.app and drag your PDF into the browser. No account needed.

Step 2: SafeRedact's AI scans the document and highlights detected PII — names, SSNs, addresses, phone numbers, emails, dates of birth, and financial account numbers. Each detection is color-coded by category.

Step 3: Review the detections. Add anything the AI missed. Remove any false positives. You have full control.

Step 4: Click Apply. Permanent pixel-burn redaction destroys the sensitive data. Download the clean output file.

The entire process takes under 60 seconds for a typical document. A 12-page contract with 20+ PII instances takes about 47 seconds from upload to download.

Why "Free" Matters for Redaction

Most people who need to redact a document need to do it right now. A landlord asks for a redacted bank statement. A lawyer needs to file a motion with sealed information. An HR manager needs to share an employee file with personal details removed. In these moments, a free tool that works immediately is worth more than an enterprise platform with a 14-day procurement process.

That's why SafeRedact's free tier has no signup, no trial period, and no daily limits. The watermark is the only difference between free and paid — and for most personal use, the watermark is a non-issue.

Frequently Asked Questions

Do I need to create an account?

No. The free tier requires no signup, no email, and no credit card. Just go to saferedact.app and start redacting.

What file types are supported?

SafeRedact supports PDF documents and image files (PNG, JPG). For Word documents, export to PDF first (File → Save As → PDF) or use ModernPDF for free conversion, then redact the PDF. See our Word redaction guide →

Are my documents safe?

Yes. Documents are processed in your browser — no complete file is ever uploaded to a server. AI detection uses Anthropic's API via bank-grade TLS 1.3 encryption, with zero data retention. The AI provider does not store or train on your data. Read our full privacy architecture →

Is free redaction good enough for legal or compliance use?

The redaction quality is identical between free and paid plans — same AI detection, same permanent pixel-burn redaction, same security. The only difference is the watermark. For formal legal filings or regulatory submissions, the watermark may be inappropriate — use a day pass ($5) for those situations.

How does SafeRedact compare to Adobe Acrobat for redaction?

Adobe Acrobat Pro costs $22.99/month and requires desktop installation. It has no AI detection — you must manually select every item to redact. SafeRedact is free, runs in your browser, and uses AI to automatically find PII. Adobe's advantage is metadata sanitization and broader format support. See our full Adobe comparison →
