Legal work runs on PDFs. Contracts, court filings, discovery documents, deeds, witness statements, compliance reports — the PDF format dominates the legal industry for good reason. It's non-editable, it's universally readable, and it preserves the exact layout of the original document.

But working with legal PDFs has specific requirements that go beyond what most people need. You need to redact confidential information before sharing documents. You need to sign contracts electronically. You need to combine case files without creating a mess. And you need to know your files are secure.

This guide covers the PDF tools that matter most for legal work.

1. Redacting Sensitive Information

Redaction is probably the most critical PDF skill in legal practice. Before sharing discovery documents, submitting court filings, or responding to Freedom of Information requests, you need to permanently black out confidential information — personal data, privileged communications, financial details, witness addresses.

The word "permanently" is important here. Simply drawing a black box over text in most PDF editors doesn't actually remove the underlying text — it just covers it visually. Anyone who knows what they're doing can remove that cover layer and read what's underneath.

Redact PDF — Redact PDF draws solid black boxes over the text you select. Because a box alone can leave the text underneath, finish by converting the pages to images (PDF to PNG, then PNG to PDF) and check that nothing can be selected or searched before you share or file.

What to redact in common legal documents:

• Personal identifiers (SSNs, passport numbers, dates of birth)
• Privileged legal advice in document productions
• Confidential settlement terms
• Witness contact details in public filings
• Medical information in employment disputes
• Financial account numbers in divorce proceedings

2. Electronic Signatures for Contracts

The days of printing a contract, signing in wet ink, scanning it back, and emailing the scan are largely over. Electronic signatures are legally binding in most jurisdictions — including under the UK's Electronic Communications Act, the US ESIGN Act, and the EU eIDAS Regulation.

Sign PDF — Draw your signature directly on screen, upload an image of your handwritten signature, or type your name. Apply it to the correct signature line in the document. Download the signed copy.

For basic client contracts, engagement letters, and consent forms, this is entirely sufficient. For high-stakes documents that may face challenge (major commercial contracts, deeds, court documents), you may want a dedicated e-signature platform that provides an audit trail — but for the majority of routine legal paperwork, PDF HUB 24's signing tool is perfectly adequate and costs nothing.

3. Protecting Confidential Documents

Client files, legal advice, privileged communications — legal professionals have a professional duty to protect confidential documents. Password-protecting PDFs before sending them by email adds a critical layer of security.

Protect PDF — Add 256-bit AES encryption with a password of your choice. Set separate permissions if you want to allow viewing but prevent editing or printing. Share the password with the recipient through a separate channel (phone or encrypted message, not the same email as the document).

4. Removing Protection from Files You Have Rights To

Sometimes you need to work with a password-protected PDF that was protected by your own firm — an old file where the password has been lost, or a protected template that needs to be updated.

Unlock PDF — Remove password protection from files you have authorisation to access. This is for legitimate use on files you own or have permission to modify.

5. Merging Case Files and Discovery Documents

Discovery involves dozens, sometimes hundreds, of separate documents that need to be organised, paginated, and often submitted as a single combined file. Contract negotiations involve multiple draft versions and side letters. Court submissions often require exhibits to be bundled.

Merge PDF — Combine up to 10 PDFs at a time, in any order. Drag to reorder before merging. Files up to 50 MB each.

Practical workflow for bundling:

1. Organise your individual documents into a folder with numbered filenames (01_claim_form.pdf, 02_exhibit_a.pdf, etc.)
2. Upload them all to the merge tool
3. Confirm the order is correct
4. Download the bundle
5. Add a covering index/contents page as the first document if required

6. Adding Page Numbers to Legal Documents

Court submissions, contracts, and legal bundles almost always require sequential page numbering. If you've merged multiple PDFs, the individual page numbers from each document won't create a continuous sequence.

Add Page Numbers — Apply continuous page numbers across the entire merged document. Choose position (header/footer, left/right/centre) and starting number.

For solicitors in England and Wales preparing court bundles, the Practice Direction on Electronic Documents specifies that bundles must have continuous pagination — this tool handles that in seconds.

7. Extracting Relevant Pages from Large Documents

You've received a 500-page disclosure bundle but only the pages relating to your client's matter are relevant. Or you need to extract specific exhibits from a long filing.

Split PDF — Enter the page ranges you want to extract and get them as a separate PDF. You can extract multiple non-consecutive ranges at once.

8. Converting Emails and Web Pages to PDF

Correspondence often needs to be preserved in PDF format for the file. Browser-based email (Gmail, Outlook Web) can be printed to PDF, but for a cleaner conversion of HTML documents:

HTML to PDF — Convert HTML files or web pages to properly formatted PDF. Useful for preserving web-based legal research, online contract portals, or HTML-format correspondence.

9. OCR for Scanned Court Documents

Older court documents, sworn affidavits, and historical case papers often arrive as scanned images — photographs of pages, with no searchable text. This makes them essentially useless for anything except reading.

OCR PDF — Convert scanned PDFs to searchable text. Once OCR'd, you can search for names, dates, case numbers, and specific terms across hundreds of pages instantly.

Security and Confidentiality

Legal professionals rightly care more about document security than almost any other group of users. Here's what PDF HUB 24 does with your files:

• All transfers use SSL/TLS encryption (same standard as online banking)
• Files are automatically and permanently deleted from servers immediately after processing
• We never store documents, never read contents, never retain metadata
• GDPR compliant — no data is transferred to third parties
• No account or login means there's no user profile tied to your documents

For most day-to-day legal document tasks, this is entirely appropriate. For highly classified documents involving national security or major ongoing litigation, you'd be better served by an on-premise tool that never touches external servers — but for the routine work that makes up 95% of legal document handling, PDF HUB 24 is secure.
