The detail
Three differences that decide it
Where your file goes, what you pay, and what the recipient can prove.
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 on Pro, providing cryptographic proof of document integrity.
How Foxit Handles Redaction
Foxit PDF Editor is a desktop application for Windows and macOS with a web-based component for general editing. The desktop app includes standard 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 keyword. 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. At the time of writing (May 2026), Editor+ includes a 50-document Smart Redact allowance per user, with paid upgrade tiers available in-app for higher volumes.
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.
Your document is uploaded to the cloud before Smart Redact can detect anything
Detected in your browser tab; the file never leaves your device
The manual redaction tools - selection, search by text, search by pattern - all run locally on the desktop app. So there is 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, identifying 60+ PII types with no upload. The Precision Engine sends extracted text - not the document - to Cloudflare Workers AI for deeper analysis, where it is 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 they are supplementary to the desktop experience rather than standalone tools.
The Foxit PDF Reader - the free product - does not include redaction at all. You need a paid PDF Editor subscription for even the basic manual tools. This catches people out: the Reader is widely used as a free PDF viewer, but redaction is a feature exclusive to the paid editor tiers. For a detailed look at what the free version can and cannot do, see the common redaction mistakes guide for why attempting workarounds like drawing black shapes over text creates a false sense of security.
RedactProof runs in any modern browser with no installation. This is useful when you are working from a client's office, a shared machine, or any environment where installing desktop software is not an option.
Pricing
At the time of writing (May 2026), Foxit PDF Editor costs £109.87/year (approximately $139.99/year USD) and includes manual redaction and pattern-based search - but not Smart Redact AI. PDF Editor+ with Smart Redact, eSign, and mobile access is £135.23/year ($172.79/year USD). Both are annual subscription plans; pricing shown is the "paid in full" annual rate.
The Smart Redact quota on Editor+ is 50 documents per user. Upgrade tiers for higher volumes are available via in-app purchase. For an enterprise cloud deployment, Foxit's Smart Redact Server is a separate product starting at $1,000/year per terabyte. For teams processing property transactions or SAR responses regularly, the per-document quota adds a variable to the budget that does not exist with a flat subscription model.
RedactProof's free trial covers one document with full Pro-level features; Flex Packs and Core cover ongoing pattern-based recognition and pixel-burn redaction. On-device AI detection starts on Core (£190/year), with no document caps on any paid tier. See how the pricing stacks up in detail in our redaction software buyer's guide.

Foxit vs Adobe Acrobat for Redaction
Foxit is the most common alternative people consider when Adobe Acrobat's pricing becomes the sticking point. The comparison is worth making directly. At the time of writing (May 2026), Adobe Acrobat Pro - the tier that includes redaction - costs £19.97/month ($19.99/month USD) on an annual plan. Foxit PDF Editor with manual redaction costs £109.87/year (roughly £9.16/month). That's a meaningful difference if you use the tool across a team.
The practical gap for redaction-heavy work: Adobe's redaction is pattern-only (no contextual AI). Foxit's Smart Redact adds AI detection but sends files to Azure and limits you to 50 documents at the Editor+ base tier. Neither product detects PII in the browser. If document confidentiality rules out cloud uploads entirely, both tools limit you to manual and pattern-based redaction only. For the full breakdown, see our Adobe Acrobat comparison.
The Practical Decision
Foxit PDF Editor is a capable, well-regarded 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 at a lower price. It also runs on Linux - unusual for commercial PDF editors.
The Smart Redact quota and Azure cloud requirement are the constraints to weigh. A busy conveyancing firm typically handles several documents per transaction - contracts, ID verification, mortgage deeds, proof of funds. A sole trader processing a modest caseload might stay within the 50-document allowance comfortably. A compliance team running monthly SAR responses for a mid-size employer probably will not.
If your data handling policy does not permit uploading client documents to third-party cloud infrastructure - common in regulated legal and healthcare environments - Smart Redact is not available regardless of the quota. Foxit's own documentation is clear that the AI processing happens on Azure. For those cases, the choice is between Foxit's manual tools or a browser-based tool with on-device AI. For more on what that distinction means in practice, see our guide on browser-based vs desktop redaction.
The verdict
A capable editor. But its AI redaction means uploading to the cloud.
- Foxit makes you choose: manual redaction on the desktop, or automatic detection that uploads to Azure. RedactProof does automatic detection in your browser, with the file never leaving it.
- No 50-document quota and no Editor+ subscription: detection is unlimited and the pricing is flat and published.
- Every export can carry a certificate the recipient verifies for themselves, offline and without an account.
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 redaction permanently remove text?
Yes, when applied correctly. Foxit PDF Editor's redaction tools work by permanently deleting the underlying content from the PDF data structure - not simply drawing a black box over it. The critical step is choosing "Apply Redactions" after marking content. If you save a file with marks pending but not applied, the black boxes appear visually but the text underneath remains in the file and can be extracted by anyone with basic PDF tools. For organisations complying with GDPR, FOIA, or SAR requirements, always apply redactions and use the sanitise function before sharing a document.
Can I redact PDFs in Foxit free?
No. Foxit PDF Reader - the free download - is a viewer only and does not include redaction tools. Redaction requires a paid Foxit PDF Editor subscription. At the time of writing (May 2026), the entry subscription is £109.87/year and includes manual redaction and pattern-based search. AI-powered Smart Redact requires the higher Editor+ tier at £135.23/year. RedactProof offers a one-document free trial with full Pro-level features; ongoing pattern-based recognition and pixel-burn redaction are available via Flex Packs, Core, or Pro.
Does Foxit upload my files to their cloud?
It depends which feature you use. Manual redaction - drawing boxes, searching by text, searching by pattern - runs entirely on the desktop without any upload. Smart Redact AI, available on the Editor+ tier, does upload documents to Microsoft Azure for processing. Foxit states they apply a zero-retention policy: files are deleted after the task completes and data is encrypted throughout. But the document does leave your device. If your organisation's data handling policy restricts uploading client or patient files to third-party cloud infrastructure, this matters for Smart Redact specifically - not for the manual tools.
Is Foxit's redaction better than Adobe Acrobat's?
For AI detection, Foxit has the edge - Smart Redact on Editor+ identifies PII categories automatically, while Adobe Acrobat relies entirely on manual selection and regex pattern matching with no contextual AI. For batch processing with defined patterns, Adobe's Action Wizard is more mature. On price, Foxit PDF Editor at roughly £9/month undercuts Adobe Acrobat Pro at £19.97/month significantly. The constraint on Foxit's AI: it uploads files to Azure and limits you to 50 documents on the base Editor+ plan. If you are weighing both options, the full comparison is in our Adobe Acrobat vs RedactProof page.
Why switch from Foxit to RedactProof?
Foxit is a capable general PDF editor. The case for switching centres on three things. First, document privacy: RedactProof processes everything in your browser with no upload to any server - useful if your clients or employer restrict cloud data handling. Second, detection depth: RedactProof's AI identifies 60+ PII types in context, not just items matching a preset pattern. Third, verification: every RedactProof export includes a tamper-evident certificate with an Ed25519 digital signature and QR code, letting anyone confirm the document is exactly what was exported. If Foxit's document scope is working for you and you do not need AI detection, there is no compelling reason to switch.
