Top 10 PDF tools every litigator needs

Every document production

Sequential page identifiers are the backbone of a production. Every page gets a unique number in an unbroken sequence so a motion, a transcript, and an appellate brief can all point at the same page without ambiguity. Prefix, start number, and zero padding should be configurable, and the sequence must carry forward correctly across rolling productions.

Practice tip: Pick your padding width once per case and never change it. ABC000001 and ABC1 in the same production is a sorting problem you will discover at the worst time.

Depositions, hearings, and trial

Exhibit labels mark a document as Exhibit A or Plaintiff's Exhibit 12, applied once to the first page. They sit alongside Bates numbers rather than replacing them, and they must be offset so the two marks never collide.

Practice tip: Apply Bates numbers to the whole set first, then exhibit labels document by document. Reversing the order is the most common cause of gaps.

Privilege, personal data, and sealed material

Redaction must remove the text layer, not cover it. Cosmetic black boxes have repeatedly exposed sealed information in high-profile filings, because anyone can select and copy the text underneath. Pattern-based detection for Social Security numbers and account numbers helps, but verification is still manual.

Practice tip: After redacting, open the file and try to select text inside the black box. If anything copies out, the redaction failed.

Scanned exhibits and legacy records

Optical character recognition adds a searchable text layer to scanned pages. Without it, keyword review silently misses documents and courts that require text-searchable filings will reject the submission.

Practice tip: Run OCR before review, not after. A privilege screen against image-only documents is not a privilege screen.

Building exhibit binders and filing packages

Combining a motion, declaration, and exhibits into one filing, or splitting a 900-page production into court-sized volumes, is routine. Page-level control including rotation, deletion, and reordering keeps assembled packages clean.

Practice tip: Assemble first, stamp second. Stamping before assembly produces out-of-order Bates ranges inside a single filed document.

Long briefs and appellate records

Many courts require bookmarked exhibits and internal links from a table of contents or exhibit index. A judge who cannot navigate a 400-page appendix will not go looking for your best document.

Practice tip: Name bookmarks with both the exhibit label and the Bates range so the sidebar doubles as an index.

Finding the document you know exists

Cross-document search over an entire production set is what turns a folder of PDFs into something usable. It also confirms whether a keyword actually appears where you believe it does before you assert it in a brief.

Practice tip: If a search returns nothing on a scanned document, the problem is usually missing OCR, not a missing document.

Before anything leaves the firm

PDFs carry author names, editing history, comments, and sometimes tracked-change residue from the source file. Producing that unintentionally is an avoidable disclosure.

Practice tip: Inspect and sanitize the document before production unless the ESI protocol specifically requires metadata preservation.

Archival filings and agency submissions

PDF/A is an ISO archival profile that embeds fonts and forbids external dependencies so files render identically in the future. Several courts and agencies require it, and it is the safest format for long-term record retention.

Practice tip: Convert to PDF/A after stamping, not before, so the Bates and exhibit marks are part of the archived file.

Delivering and tracking the production

A production index maps every file to its exhibit label, Bates range, and page count. It is what lets you answer 'what did we produce, when, and where is it' six months later without reopening every PDF.

Practice tip: Export the index at the same moment you export the stamped files. Reconstructing it later is manual work nobody enjoys.

What PDF software do law firms use?

Most firms rely on a combination: a full desktop PDF editor for redaction and OCR, a browser-based tool for Bates numbering and exhibit stamping, and the court's electronic filing system for final submission. Larger firms add a hosted review platform for productions above a few thousand documents.

What is a true redaction in a PDF?

A true redaction removes the underlying text and image data from the file, not just the visual appearance. Drawing a black rectangle over text leaves the text extractable by anyone who copies from the PDF, which has produced repeated disclosures of sealed material in federal filings.

Do I need OCR for court filings?

Many courts require text-searchable PDFs for electronic filing, and scanned documents are not searchable without OCR. Even where it is not required, OCR is what makes keyword review and privilege screening reliable across scanned records.

What is PDF/A and when do litigators need it?

PDF/A is an ISO-standardized archival format that embeds fonts and prohibits external dependencies so the file renders the same decades later. Some courts and agencies require it for filings and record submissions.

How do I reduce PDF file size for court filing limits?

Downsample embedded images, remove unnecessary embedded fonts, and flatten form fields and annotations. Avoid compressing so aggressively that scanned text becomes illegible, since most courts require legible filings regardless of size limits.

Should litigators use one PDF tool or several?

Several, matched to the task. A single editor rarely does Bates numbering, redaction, OCR, and archiving equally well, and using a purpose-built tool for stamping is faster and safer than forcing a general-purpose editor into a production workflow.
