How Foxit Handles Redaction
Foxit PDF Editor is a desktop application for Windows and macOS with a cloud component for AI features. The desktop app includes manual redaction - draw boxes over content, mark text, apply - and a solid Search and Redact function with built-in patterns for SSNs, phone numbers, email addresses, and dates. You can also search by custom keywords. These tools run locally on your machine.
Foxit also offers Smart Redact on the Editor+ subscription tier. Smart Redact uses AI to detect PII categories including names, identification numbers, phone numbers, email addresses, and credit card numbers. Foxit claims 99%+ accuracy, though this is not independently verified. As of February 2026, Editor+ includes a 50-document Smart Redact allowance, with paid upgrade tiers from 200 to 2,400 documents per year.
Where Smart Redact Processes Your Files
Smart Redact does not run locally. Documents are uploaded to Foxit's cloud infrastructure hosted on Microsoft Azure. Azure AI Vision handles OCR for scanned documents. Azure AI Language Service identifies the sensitive information. Foxit states they maintain a zero-retention policy - files are deleted after processing, and content is not used for training.
The manual redaction tools - selection, search by text, search by pattern - all run locally on the desktop app. So you face a choice: local processing without AI, or AI detection that requires uploading to Azure.
RedactProof does not require that trade-off. The standard engine runs AI detection entirely in your browser using WebAssembly. Pro Engine sends extracted text - not the document - to Cloudflare Workers AI for deeper analysis, processed in volatile memory only. Your PDF stays on your device regardless of which detection method you use.
Desktop App vs Browser Access
Foxit PDF Editor requires installation. The full redaction feature set lives in the desktop app; the web-based Foxit PDF Editor Cloud has more limited capabilities. Mobile apps on iOS and Android come with the Editor+ subscription, though these are supplementary to the desktop experience.
RedactProof runs in any modern browser with no installation. Useful when you are working from a client's office, a shared machine, or any environment where installing desktop software is not practical.
Pricing
At the time of writing (February 2026), Foxit PDF Editor Standard costs $129.99/year (approximately $10.83/month) and includes manual redaction but not Smart Redact AI. Editor+ with Smart Redact is $172.79/year. The Smart Redact quota on Editor+ is 50 documents. Perpetual licences are available at around $179-199 for the standard version, though these exclude cloud features and future updates.
For an enterprise deployment, Foxit's Smart Redact Server is a separate cloud-only product starting at $1,000/year per terabyte, available in US, EU, and Canada data regions.
RedactProof's free tier includes unlimited pattern-based recognition and pixel-burn redaction. AI detection starts at £19/month on the Core plan with no document caps.
The Practical Decision
Foxit PDF Editor is a capable, affordable PDF suite. Reviewers consistently praise its startup speed, text editing quality, and Office-style ribbon interface. If you need a general-purpose PDF editor for forms, annotations, conversions, and e-signatures alongside occasional redaction, Foxit competes well with Adobe Acrobat at a lower price point. It also runs on Linux - unusual for PDF editors.
The Smart Redact quota and Azure cloud requirement are the constraints to weigh. Editor+ includes 50 documents; upgrade tiers run from 200 to 2,400 documents per year. Each property transaction typically involves several documents - contracts, ID checks, mortgage deeds, proof of funds - so a busy conveyancing firm could work through even the higher-tier allowances. And if your data handling policy does not permit uploading client documents to third-party cloud services - common in legal and healthcare settings - Smart Redact is not an option regardless of the quota. RedactProof's AI detection runs in the browser specifically to avoid both limitations.
Why Choose RedactProof over Foxit PDF
The features that set RedactProof apart for secure document redaction.
Unlimited AI Detection, No Cloud Required
Foxit's Smart Redact detects PII categories using Azure AI services - a real capability on the Editor+ tier. Two constraints to note: documents are uploaded to Microsoft Azure for processing, and Editor+ includes a 50-document allowance with paid upgrade tiers from 200 to 2,400 documents per year. RedactProof's AI detection runs entirely in the browser with no upload step and no document caps on paid plans.
No Installation, Works Anywhere
Foxit PDF Editor is a desktop application. The Windows and macOS versions are full-featured; there's also a Linux build, which is uncommon among PDF editors. But desktop software needs installing, updating, and licensing per machine. If your workflow involves different devices - an office desktop, a home laptop, a client-site machine - RedactProof is browser-based and accessible from any of them without installation.
Tamper-Evident Verification
Foxit has strong e-signature audit trails with completion certificates and tamper-evident seals. Those apply to the signing workflow, not to redaction. When you export a redacted PDF from Foxit, there's no built-in mechanism to verify the file hasn't been modified after the fact. RedactProof includes an Ed25519 digital signature and QR code with every export, providing cryptographic proof of document integrity.
Where Foxit Has the Edge
Foxit is a full PDF editor - text editing, forms, OCR, conversion, and digital signatures in one package. Annual pricing at $130-$173 can work out cheaper than monthly subscriptions if you need a general-purpose PDF tool anyway. Linux support is a genuine differentiator that few PDF editors offer. And for organisations already standardised on Foxit across their workflow, keeping redaction in the same tool avoids adding another vendor.
Common Questions
What people ask when comparing Foxit PDF and RedactProof.
Does Foxit PDF Editor have AI-powered redaction?
Yes, through the Smart Redact feature on the Editor+ subscription tier (approximately $173/year at the time of writing, February 2026). Smart Redact uses Azure AI services to identify personal data categories including names, national identification numbers, email addresses, and credit card numbers. The trade-off: documents are uploaded to Azure for cloud processing, and the base quota is 50 documents. Foxit's manual search-and-redact tools work locally without any cloud involvement.
Does Foxit upload my documents when I use redaction?
It depends which feature you use. Manual redaction (drawing boxes, search-and-redact with text or patterns) runs entirely on the desktop - files stay on your machine. Smart Redact AI sends documents to Microsoft Azure for processing. Foxit states a zero-retention policy: files are deleted after the task completes, and data is AES-256 encrypted throughout. But the document does leave your device during processing.
How does Foxit's pricing compare to RedactProof?
Foxit PDF Editor Standard runs approximately $130/year and covers manual redaction, pattern search, OCR, and general PDF editing - but not AI detection. Editor+ at about $173/year adds Smart Redact with the 50-document quota. RedactProof's free tier includes unlimited pattern-based recognition. The Core plan at £19/month (£190/year) adds unlimited AI detection. Foxit can be cheaper if you only need manual redaction tools and want a full PDF suite.
What is Foxit's Smart Redact document limit?
At the time of writing (February 2026), Editor+ includes a 50-document Smart Redact allowance. Beyond that, Foxit offers upgrade tiers: 200, 1,000, or 2,400 documents per year. The overage pricing is available through in-app purchase. For teams processing documents in volume, this adds a budgeting variable. RedactProof's paid plans don't impose per-document limits on AI detection.
Can Foxit PDF Editor run on Linux?
Foxit does offer a Linux version - it's one of few commercial PDF editors available on the platform. If Linux support is a hard requirement and you need a desktop PDF suite with redaction, Foxit is worth considering. RedactProof sidesteps the operating system question entirely - it runs in any modern browser on Windows, macOS, Linux, or ChromeOS without installation.
