Every Word document and PDF carries more than the words on the page - that’s metadata. Author names, edit history, comments, tracked changes, file paths and timestamps can all travel with a file, whether or not anyone meant them to.
For law firms, being able to remove metadata from Word documents and remove metadata from PDF files isn't a technical nice-to-have. It's part of protecting client confidentiality, firm reputation and negotiating position.
Why metadata builds up in legal work
Before working in legal tech, I worked in a general practice law firm across property, criminal, family and corporate law. Like most firms, we relied on existing documents, precedents, templates and prior work to move quickly and stay consistent. Whilst that’s generally normal legal practice, it creates a risk that when a document is handed back to a client, hidden information like comments or tracked changes may be missed.
A metadata cleaning solution (sometimes called metadata scrubbing) removes that risk by stripping that hidden layer out, before a document leaves the firm.
Three consistent themes we hear from law firms about document metadata
Precedent reuse can expose who really wrote it
When metadata isn't cleaned, the original author or originating firm can still be visible underneath. Documents are often built from previous files. That's not unusual or improper; it is how good legal work gets done efficiently, especially for smaller firms that don’t have teams dedicated to precedent file building.
We've heard firms describe using best practice, negotiated contracts that were originally owned by another firm as a starting point, only for the metadata to reveal the original author to a client. That can be embarrassing, commercially sensitive, or reputationally damaging, especially when the other side or a client notice first.
Metadata can undermine legal strategy
Metadata isn't only a confidentiality issue; it can become a strategic one.
Some firms tell us they look at Word file metadata, including authors, contributors and total editing time, to understand who's been involved in a document and how much attention it's had. In a negotiation or dispute, that detail shapes how the other side reads your position. Senior involvement, repeated revisions, or heavy drafting time can all signal something you didn't intend to share.
Metadata cleaning is becoming a client requirement
Some major clients now require their law firms to use metadata cleaning software as part of their own security and compliance expectations.
One firm told us that one of their largest clients required metadata cleaning software as a condition of the relationship. For that firm, cleaning metadata became part of keeping the client.
Why we built Draftable Clean
There are many metadata cleaning tools in the market, so there were questions on whether the economics stood up to offer this solution. What we heard loud and clear from lawyers and legal teams though was the Comparison and Metadata cleaning go hand in hand in their work practice. Law firms told our team they liked Draftable's comparison experience, the simple interface and responsive support (which consistently receives a 95%+ CSAT score), but didn't want to be pushed into a large, bundled product just to get comparison and metadata cleaning together.
So we did what we always do and built it with the legal profession, rather than for it. Draftable Clean is a focused, easy-to-use metadata scrubber for legal documents that fit into their workflows and the controls their firms already run.
Metadata removal is more than a security task
Metadata cleaning protects client confidentiality, preserving a negotiating position, avoiding reputational risk and exceeding client expectations.
Whether you need to remove metadata from Word, remove metadata from PDF, or put a consistent metadata scrubber in place across the whole firm, the goal is the same, the document has to say only what you intend it to say.

Common questions
What metadata does a Word document contain?
This can contain author and last-modified-by names, company name, created date, modified dates, tracked changes, comments, revision history, total editing time, file paths, template names and custom document properties.
What metadata does a PDF contain?
PDFs can contain an author, creator, producer, creation and modification dates, keywords, identifiers, document versions, annotations and bookmarks.
Is removing metadata the same as redaction?
No. Redaction removes visible content from the page. Metadata removal solutions like Draftable Clean strip the hidden information attached to the file. A document can be fully redacted and still shows who drafted it and when.
Does Word's Document Inspector remove all metadata?
It does remove some metadata; however, it works file by file, relies on the sender to remember to run it and does not cover PDFs or apply firm-wide standards. Most firms need something that applies consistently without depending on manual intervention.
