For law firms & in-house counsel

PDF tools that keep privileged files on your machine.

Files never leave your browser. No uploads. No retention. No vendor-side copy to subpoena.

A document sealed inside a Faraday cage. Your files stay fully private, on your device. A document sealed inside a Faraday cage. Your files stay fully private, on your device.

The rule you're trying not to violate.

One model rule, two influential state bar opinions, and a growing line of malpractice claims.

ABA Model Rule 1.6: Confidentiality of Information

A lawyer shall not reveal information relating to the representation of a client unless the client gives informed consent, the disclosure is impliedly authorized in order to carry out the representation, or the disclosure is otherwise permitted.

Several state bar ethics opinions (including NY State Bar Opinion 842 and Cal. Bar Formal Opinion 2010-179) have held that lawyers must make reasonable efforts to assess vendor security before using cloud services. Uploading a client document to a third-party PDF processor without that diligence has been argued to potentially constitute a disclosure absent informed consent.

What a single upload can cost you.

Privilege waiver

Disclosure to a third-party processor can be cited as a waiver, by opposing counsel and by your own insurer.

Malpractice carrier scrutiny

Some malpractice carriers now ask about your vendor stack at renewal. Cloud uploads of client material can raise premiums or trigger exclusions.

Opposing counsel discovery

A subpoena to your vendor produces logs, copies, and metadata you never thought you'd hand over.

Built for how lawyers actually use PDFs.

Automatic redaction with audit certificate

High-profile document releases have repeatedly shipped redactions that could be defeated by copy-paste. KeptPDF auto-detects names, dates and identifiers, destroys the underlying text layer (not just the visible box), and signs the output with a SHA-256 hash.

Bates numbering for productions

Stamp continuous Bates numbers across an entire production, with prefix, padding, and a re-stamp lifecycle for new discovery rounds, then export a range report and CSV load file. OCR, redaction, and Bates in one local-only workflow.

Exhibit stamps & binders

Label each document as Exhibit A, B, C: a corner sticker, auto "EXHIBIT A" divider sheets, a combined binder, and a downloadable exhibit index. Built for motions, depositions and trial. Runs entirely in your browser.

Metadata scrub

Redaction rebuilds the PDF from scratch, stripping XMP, hidden layers, comment threads, prior author names and embedded revisions in the same pass.

No telemetry on files

We log nothing about your documents: no names, no sizes, no hashes. Auditable. Verifiable on the Verify page.

Compare & redline

Diff two versions of a contract or brief side by side. Additions and deletions are highlighted automatically, all in your browser.

How we compare.

Same task. Very different exposure profile.

✓ yes · – partial · ✗ no. Marks reflect each product's default workflow as of May 2026. Adobe Acrobat's desktop app processes files locally while its online tools upload by default; Acrobat's "Remove Hidden Information" does strip metadata, but neither competitor ships a verifiable redaction certificate. iLovePDF's web tools process every file on their servers. On a phone: Acrobat's mobile app has no redaction tool at all (it lives on desktop/web), so even paid users can't redact there; iLovePDF's app does redact but only by manually drawing boxes or typing a keyword, and neither auto-detects names, SSNs or emails on-device. KeptPDF's automatic detection and redaction run entirely in a mobile browser.

Privacy is table stakes. Legal work needs more.

SimplePDF and LocalPDF also process files in your browser, and credit where it's due. Here's what KeptPDF adds for redaction that holds up in litigation.

Capability KeptPDF SimplePDF LocalPDF
Files stay in your browser, never uploaded
Automatic PII & name detection, not just manual boxes
Verifiable SHA-256 redaction audit certificate
Bates numbering with load file & production report

Credit where due: all three process files in your browser. KeptPDF adds the legal-grade layer: automatic detection, redaction that destroys the underlying text (not just black boxes), a SHA-256 audit certificate, and Bates numbering. Self-hosted suites like Stirling-PDF offer more general tools but require running your own server. Feature sets per each product's own site, May 2026.
