What your Word document is hiding
Every .docx file is a ZIP archive containing XML files. Alongside the visible text, Word stores a separate set of document properties that travel silently with the file whenever you share it:
Author & last-modified-by
The Windows login name or Microsoft account of the person who created and last saved the document. This is often a real name or an employee ID.
Company name
Pulled from the Office installation's registered organisation at install time. May reveal an employer, client, or internal team.
Revision number
Increments on every save. A revision of 47 tells the recipient this draft went through many internal iterations, even if tracked changes were accepted.
Total editing time
Accumulated open time in minutes. A document edited for 4 hours vs 30 minutes sends very different signals about how much thought went into it.
Template path
Full file-system path of the Word template used — which can expose internal network share names, user profile paths, or project codenames.
Tracked changes & comments
Unaccepted insertions and deletions remain in the XML even after accepting all changes in the UI, depending on how they were cleared. Comments may also persist.
SimpleTool reads this metadata and surfaces it before you convert. The PDF your browser generates contains none of it — the browser's print engine receives only the rendered HTML, not the original Word properties.
Zero-server processing
The .docx file is parsed locally by mammoth.js and JSZip — both running in WebAssembly or pure JavaScript inside your browser tab. No file ever reaches a server.
Metadata-first transparency
You see exactly what was embedded before you commit to sharing. Author, company, revision, template path, tracked changes — all surfaced in a single report, sensitive fields highlighted in amber.
Clean, text-searchable PDF
The browser's native print engine converts the rendered HTML to a text-searchable PDF. No image-based rasterisation, no jsPDF blobs — the output is indistinguishable from a Word-exported PDF, minus the hidden metadata.
When to use this converter
Real situations where checking metadata before sharing a Word document matters.
Legal documents & contracts
Sharing a draft NDA or contract externally while the author name and revision count would reveal internal back-and-forth. Convert to PDF to strip the revision history before it leaves the building.
Job applications & CVs
A CV authored from a recruiter's or agency's template carries the template path and company name in its metadata. Sending it to a hiring manager with a recruitment firm's fingerprint is an avoidable disclosure.
Financial reports & proposals
Investor decks and client proposals drafted over many sessions accumulate high revision counts and long editing times. Converting to a clean PDF removes those negotiating-position signals.
Government & public-sector submissions
FOI responses, planning documents, and policy papers are routinely scrutinised for metadata after submission. Converting to a browser-generated PDF before publication removes identifiable author data.
Research & academic papers
A paper under blind review should not carry the author's institution name in its Word metadata. Convert to PDF with metadata stripped before uploading to submission portals.
IT-restricted corporate laptops
Many corporate environments block installing PDF export plug-ins or restrict access to cloud converters. A browser-based converter works without any installation or network access to a third-party server.
Frequently asked questions
Does my Word document leave my device?
No. The entire conversion runs in your browser using mammoth.js (DOCX to HTML) and JSZip (metadata parsing). The file is never uploaded to any server. SimpleTool has no backend that processes documents.
Why does the metadata report matter?
Microsoft Word embeds the author's name, company, login name, revision count, total editing time, and template file path in every .docx file. When you share a Word document these details travel with it. Even when you export to PDF using Word, some of this metadata can be preserved. SimpleTool's converter uses pdfmake, which only receives the document's HTML content — author, company, and revision history are never passed to the PDF engine, so the output is clean by default.
What happens to tracked changes?
mammoth.js converts the document to its final accepted state by default: insertions are shown, deletions are hidden — the same result as pressing "Accept All" in Word. The PDF reflects the final clean text. If the document has active tracked changes, the metadata report shows you how many were present so you can decide whether to review them in Word first.
Will the PDF look exactly like the Word document?
Layout fidelity is high for text-heavy documents. Complex features that may not transfer perfectly include: custom fonts (the PDF uses the browser's system fonts), multi-column layouts, text boxes, WordArt, and complex table borders. A preview panel lets you check the content before converting. For pixel-perfect fidelity, open the document in Word and use Word's own Export to PDF.
What file formats are supported?
Only .docx (Office Open XML, introduced in Word 2007). Legacy .doc files (Word 97-2003 binary format) are not supported because they use a proprietary binary format that requires a different parser. If you have a .doc file, open it in Word or LibreOffice and save it as .docx first.
Is there a file size limit?
There is no hard limit set by SimpleTool — it depends on your device's available browser memory. In practice, Word documents are rarely larger than 50 MB unless they contain many high-resolution embedded images. Documents of that size convert without issues on modern hardware.
