Contracts almost always arrive as PDFs because the sending party wants to lock the document's appearance and prevent accidental edits in transit, but legal review, clause-by-clause redlining, comment insertion, and negotiation work most naturally in Microsoft Word.

Redlining is the standard legal practice of marking proposed changes to a contract so both parties can clearly see what was added, deleted, or modified during negotiation. Microsoft Word's Track Changes feature has been the industry tool for redlining for more than two decades, supported by every law firm, every in-house legal team, and every reputable contract management workflow. It records every edit with the author name, the date, and the time, showing insertions underlined and deletions struck through in a contrasting colour, with each reviewer's changes appearing in a distinct colour automatically. Most law firms and corporate legal departments require contracts to be reviewed in Word with Track Changes enabled. When a contract arrives only as a PDF, which is common for first drafts, supplier templates, and signed agreements being reopened for amendment, converting it to .docx is the necessary first step before any markup can begin.
Once you have the .docx from FixTools, the redlining workflow runs cleanly. Open the file in Word, navigate to Review > Track Changes > Track Changes, or press Ctrl+Shift+E to toggle, and begin editing. Every keystroke from that point onward is recorded with your user name attached, which should match the name configured in File > Options > General > User name so that the counterparty knows exactly who proposed each change. To add a margin note without editing the underlying text, select the relevant clause and click Review > New Comment. Comments appear in a margin balloon and remain visible to every reviewer who opens the file. When you share the marked-up .docx with the counterparty, they can accept or reject each change individually using Review > Accept and Review > Reject, creating a clear audit trail for every negotiated point in the document.
Confidentiality is a real and often pressing concern when converting legal documents, particularly commercial agreements that contain pricing schedules, intellectual property assignments, personal data, employee compensation, or trade secrets. FixTools processes the entire conversion locally in your browser using JavaScript: your contract PDF is read into browser memory, parsed by the local conversion engine, and the resulting .docx is generated from that in-memory data without ever leaving your device. Nothing is transmitted to any FixTools server at any point during conversion, and there is no logged copy of the file on any remote system. You can verify this independently by opening your browser's Developer Tools (F12 in Chrome, Edge, and Firefox), switching to the Network tab, and watching for file upload requests during conversion. There are none. For contracts covered by NDAs, including M&A transaction documents, this local-processing model is the appropriate and often only acceptable choice.
After negotiation concludes, there is one more step worth running before circulating the final agreed Word draft externally for signature conversion. Use Word's Document Inspector at File > Info > Check for Issues > Inspect Document to surface and remove hidden metadata that you may not want to share, including revision history, deleted comments, the names of all previous reviewers, hidden text marked as such, and document properties such as your firm's template path. This last step typically takes thirty seconds, and missing it has led to real-world embarrassments where private internal commentary or earlier draft positions accidentally travelled with a contract to the counterparty. Once inspected and cleaned, run the file through FixTools Word to PDF for the final, signature-ready PDF.
Upload your PDF contract and convert to Word. Open the .docx in Microsoft Word, enable Track Changes, and mark up the document for legal review or negotiation.
Step-by-step guide to convert a pdf contract to word for editing:
Upload your contract PDF
Open the FixTools PDF to Word converter in any modern browser and drag your contract PDF onto the upload zone or click Browse to select it from your filesystem. The file is read directly into browser memory using the File API and is never transmitted to a third-party server, which matters for legal documents that often contain confidential commercial terms, personal data, and trade secret references that should not leave your device.
Convert to Word
Click Convert to Word and the conversion engine extracts the contract text, preserves numbered clause hierarchies, retains heading levels for parts and schedules, and reconstructs tables found in pricing exhibits or schedules of services. A typical fifteen to twenty page commercial agreement completes in roughly five to ten seconds on a modern laptop, and a heavier sixty page master services agreement still finishes in under thirty seconds without any server round trip.
Open in Word with Track Changes
Open the resulting .docx in Microsoft Word and switch to the Review tab. Click Track Changes, or press Ctrl+Shift+E on Windows or Cmd+Shift+E on Mac, to enable redlining before making any edits. Verify your name is set correctly under File > Options > General > User name so that every tracked change is attributed to you rather than to a generic User 1 label, which is meaningless to the counterparty receiving the file.
Add comments and revisions
Mark up the contract by editing clauses directly to record proposed deletions and insertions as tracked changes, and use Review > New Comment to add margin notes raising questions or flagging issues for internal discussion. Share the marked-up .docx with the counterparty by email or secure file share. The recipient can open it in Word or Google Docs, see every change clearly, and accept, reject, or counter each proposal in their own coloured layer.
Convert final version to PDF
Once both parties have agreed every redline, accept all tracked changes in Word via Review > Accept > Accept All Changes, save the clean final draft, then run the .docx through the FixTools Word to PDF tool to produce the polished final contract PDF ready for electronic signature in DocuSign, Adobe Sign, HelloSign, or any other e-signature platform your business uses.
Common situations where this approach makes a real difference:
In-house counsel
An in-house lawyer at a mid-sized SaaS company receives a supplier services agreement from a new infrastructure vendor as a PDF, with the vendor refusing to send an editable Word version on policy grounds. They convert it to Word with FixTools in under fifteen seconds, enable Track Changes in Review, and spend forty-five minutes reviewing clauses systematically against the company's standard playbook. They propose three substantive changes: a reduction of the indemnity cap from unlimited to a multiple of fees paid, a modified termination notice period of ninety days rather than thirty, and a data processing addendum requirement to ensure GDPR compliance. They share the tracked .docx with the supplier's legal team. The entire negotiation runs through two rounds of revision over a fortnight before both parties accept the agreed changes.
Freelance contractor
A freelance senior developer receives a client services contract PDF for a six-month engagement they have never worked with before, sent over by the client's operations team without an editable source. They convert the PDF to Word with FixTools, read through the contract carefully, and use a Word comment in the margin to flag the intellectual property assignment clause for clarification because it appears to assign rights to all pre-existing background IP rather than only project-specific deliverables. They also enable Track Changes to propose striking a non-compete clause that prohibits work for any competing business for two years, which is far broader than industry standard for contract development work. The marked-up .docx with both the comment and the redlined non-compete is returned to the client within the same working day.
Small business owner
A small business owner opening a second retail location receives the landlord's standard commercial lease as a PDF, with the landlord's agent saying that any negotiation must be done through a marked-up Word draft. The owner converts the PDF to Word with FixTools, then shares the .docx with their commercial property solicitor for review. The solicitor enables Track Changes and proposes eleven substantive amendments covering tenant break clauses, rent review intervals fixed rather than upward only, service charge caps preventing runaway costs, and a clearer dilapidations schedule. The amended document is passed back and forth three times between the parties before the landlord accepts the final version, with the entire negotiation completing in just under three weeks rather than the months a less efficient workflow would consume.
Procurement manager
A procurement manager at a regulated financial services firm regularly receives vendor contracts as PDFs from a mix of small specialist suppliers and major technology platforms. Converting each one to Word with FixTools and using Track Changes to mark the firm's standard corporate terms creates a clear, durable record of exactly what each vendor was asked to accept and what they ultimately agreed to. Over twelve months, the manager processes around forty vendor contracts this way, with an average of six tracked changes per contract covering liability caps, audit rights, data residency, and termination flexibility. The audit trail produced by the tracked changes satisfies internal compliance requirements and provides a defensible record for the firm's annual procurement audit by external assessors.
Get better results with these expert suggestions:
Set your Word user name before enabling Track Changes
Track Changes records the author name for every single edit, and that name travels with the file when you share it. Before starting a serious contract review, confirm your name and initials are correctly set in Word by going to File > Options > General on Windows or Word > Preferences > General on Mac and checking the User name and Initials fields. In a multi-reviewer workflow each person should have a distinct, fully spelled name rather than a default such as User 1, an office machine login, or a placeholder. Tracked changes attributed to User 1 are essentially useless to the receiving party and can damage your credibility on the deal.
Use Compare Documents to spot differences between versions
If you have both the original contract PDF and a revised version returned from the counterparty after their internal negotiations, convert both to Word and use Word's Compare feature at Review > Compare > Compare Documents. Select the original .docx as the Original document and the updated .docx as the Revised document. Word generates a third comparison document showing every difference between the two as tracked changes, with insertions, deletions, formatting changes, and even moves flagged separately. This is dramatically faster than reading both versions manually and reliably surfaces every change, including subtle wording adjustments such as a swap from reasonable to commercially reasonable that humans often miss on a first pass.
Accept all formatting changes before distributing the redlined file
PDF to Word conversion occasionally produces minor formatting differences relative to the source, such as tiny font size variations between sections, line spacing shifts of half a point, or marginally different indents on numbered clauses. These can appear in the tracked changes panel and clutter the redline with noise that distracts from your substantive negotiated edits. Before sharing the marked-up file externally, use Review > Show Markup to display only Formatting changes, then click Accept > Accept All Changes Shown to absorb them silently. Switch the filter back to show insertions and deletions, and the recipient will see only your intentional clause-level edits.
Check that no metadata reveals confidential information
Word documents store a surprising amount of metadata behind the scenes, including author names from every reviewer who has touched the file, the full revision history of changes accepted along the way, comments that may have been deleted but linger in the file structure, template paths revealing your firm or company name, and document properties such as the original file name and last save location. Before sharing a converted and marked-up contract externally, run File > Info > Check for Issues > Inspect Document and review every category Word reports. Remove anything you do not want to disclose. This thirty second check has prevented many embarrassing disclosures of internal commentary or earlier negotiating positions.
