The detail

Three differences that decide it

Where your file goes, what you pay, and what the recipient can prove.

Detection

Detection You Do Not Have to Script

Power PDF's search-and-redact is genuinely useful, but it redacts what you tell it to find: words, phrases, patterns you define. The risk in a disclosure bundle is the identifier you did not think to search for: a National Insurance number embedded in a footer, a case reference in a table, a date of birth in a signature block, exactly the identifiers search-and-redact only catches if you already knew to look for them. RedactProof's automatic detection surfaces 60+ PII types across the document without you writing a single search, and you approve each suggestion before export.

Installs

No Install, No Licence Spreadsheet

Power PDF is a per-machine Windows install with perpetual licences to track, upgrade fees at each major version, and a separate Mac SKU. RedactProof runs in the browser on any operating system: a new fee earner opens a link and is redacting the same morning, and seat management is a settings page rather than an asset register.

Proof

Proof That Survives Sending

Power PDF removes redacted data properly, but once the file is sent, the recipient has no built-in way to confirm it has not been altered since. RedactProof issues a verification certificate with every export on Pro: an Ed25519 signature and QR code that a regulator, court or opposing counsel can check offline, no account required. That matters most in a subject access request or disclosure bundle: if opposing counsel or a regulator later asks whether the export was altered, you have an answer that does not depend on them trusting your word.

Who Actually Buys Power PDF

Tungsten Power PDF (rebadged from Kofax) sells to firms that already run Windows desktops and want a full PDF editor rather than a single-purpose tool: OCR, forms, conversion, e-signatures, and a perpetual licence they own outright. As of August 2026 that's Standard at £95 and Advanced at £131 excluding VAT, a pricing model that has genuinely become rare in this category. It's a sensible default for a paralegal team standardising desktop software, or a solo practitioner who wants one tool for everything and doesn't want a renewal notice every year.

Redaction sits inside that broader editor rather than being the product. That shapes everything about how it behaves in practice.

How Redaction Actually Works in Power PDF

Advanced gives you manual redaction, full-page redaction, and search-and-redact for words, phrases and patterns, and since v4.1 that search runs across multiple documents in one pass. Tungsten's documentation describes redaction as removing data rather than covering it, which is the correct approach for a redaction tool and matters more than the feature list around it.

The gap is upstream of removal, not in it. Search-and-redact only finds what you tell it to search for. If you know the pattern (a case number format, a fixed phrase, a list of names) it will find every instance reliably, including across a batch. If you don't know the pattern exists in the document, it stays. A National Insurance number in a footer someone forgot to search for, or a date of birth that appears once in a signature block, doesn't get flagged because nothing prompted a search for it. That's not a flaw in the software; it's the nature of a tool built around definitions rather than recognition.

PII types flagged automatically. Power PDF only redacts the search patterns you define, so the identifier you did not anticipate stays in the file.

Where the Document Sits, and Why That's Not the Real Question Here

Power PDF processes locally on a Windows machine, and Tungsten markets that as a differentiator. It's a fair one: for a firm handling privileged material or a public body managing SARs and FOIA disclosures, keeping the working file off a third-party server matters under UK GDPR's data minimisation principle, and Power PDF meets that bar. A cloud editor exists only inside Business subscriptions; the core desktop product never sends the file anywhere. RedactProof also never uploads the document, so on this specific point the two tools agree. The practical difference for a UK legal or public-sector buyer isn't where the file sits; it's what happens once a colleague, a court, or a regulator receives the export and has no way to independently confirm it wasn't altered after leaving your hands. Local processing protects the document in your custody. It says nothing about the document once it's out the door.

What Changes When You Switch the Workflow Around

In our runs, the practical difference shows up before redaction even starts. Instead of opening a search dialog and defining what to look for, RedactProof's automatic detection scans the document and surfaces 60+ PII types as suggestions, which you step through and approve or reject one at a time before anything is touched. Nobody has to remember to search for a NINO format or a date pattern; the detection pass does that work and puts it in front of you for a decision, not an automatic action. Once you export, the underlying pixels are burned out, not covered, and the file carries an Ed25519-signed certificate with a QR code. Anyone who receives the document, a court clerk, opposing counsel, a regulator, can scan that code and verify the export hasn't been altered since it was signed, without an account and without taking your word for it. That's the artefact a disclosure bundle or SAR response is often missing: not proof the redaction was done properly, but proof it stayed that way after you hit send.

The Honest Answer

If your firm is Windows-based, wants to own its software outright with no subscription, and does high-volume redaction against predictable patterns (the same case reference format, the same phrase, across a folder of files) Power PDF's batch search-and-redact and Bates numbering are real capabilities RedactProof doesn't try to replicate. That's a legitimate reason to buy it.

For everyone else, the bottom line is simpler: if you can't be certain in advance what identifiers a document contains, a tool that only redacts what you search for will miss what you didn't think to look for, and a tool that detects first closes that gap.

The verdict

Search-and-redact needs you to know what to search for.

  • Power PDF only redacts the patterns you define, so an identifier you did not anticipate slips through. RedactProof flags 60+ types of personal data automatically, then you approve each one.
  • No per-machine licence and no Windows requirement: it runs in the browser on any OS, with the document never leaving it.
  • Every export can carry a certificate the recipient verifies offline, so a filed document challenged months later still stands up.

Where Tungsten Power PDF Has the Edge

True perpetual ownership with no subscription, a full PDF editor with OCR, forms, conversion and e-signatures, and legal-workflow features RedactProof does not have: named Bates numbering and stamping, and watched-folder batch automation that runs redaction patterns across document sets. A Windows-based firm that wants to own its software outright and does high-volume, pattern-predictable redaction gets real value here.

Common questions

What people ask when comparing Tungsten Power PDF and RedactProof.

Does Power PDF Advanced include redaction?

Yes. Advanced includes manual redaction, full-page redaction, and search-and-redact for words, phrases and patterns, extended in v4.1 to run across multiple documents at once. Tungsten's documentation describes redaction as removing rather than covering data. What it lacks is automatic detection: you define what to search for, so unlisted identifiers stay in the file.

Is Power PDF a subscription?

Standard and Advanced are one-time perpetual licences, £95 and £131 excluding VAT as of August 2026, with 90 days of included support and paid upgrades between major versions. Business tiers offer perpetual or subscription licensing at volume; contact Tungsten for a quote. That perpetual model is genuinely rare now and is one of Power PDF's strongest points. For redaction specifically, that perpetual price does not include automatic PII detection or export certificates.

Is Power PDF cloud-based?

The core product is a local Windows desktop application, and Tungsten markets the fact that documents stay on your machine. A cloud editor exists only as part of Business subscriptions. On local processing, Power PDF and RedactProof agree; the differences are automatic detection, install-free access from any operating system, and verifiable exports.

Why choose RedactProof over Power PDF for redaction?

Because finding the PII is the hard part. Power PDF redacts what you search for; RedactProof finds 60+ PII types automatically and lets you approve each one. Add zero install on any platform and a tamper-evident certificate on every export, and the case is strongest wherever redaction is a recurring compliance task. If you want a full Windows PDF editor you own outright, with Bates numbering for litigation work, Power PDF is a solid tool. Try RedactProof free on one document first: no install, no card, and you will see the certificate on export before you decide.
