Send a resume
A PDF resume looks identical on every recruiter's screen regardless of their Word version, font set, or operating system. Convert before sending to lock the layout.
Convert Word documents to PDF — without Microsoft Office
Converting a Word document to PDF locks the layout so it looks the same on every screen, printer, and operating system. Shared Word files break when recipients have different font sets, older Office versions, or different default printers — PDF eliminates all of that. LuraPDF converts .docx and .doc files to PDF directly in your browser using mammoth.js and pdf-lib. No Microsoft Office install is required, no upload, and no cloud service subscription.
Most online Word to PDF converters send your document to a remote server for processing. That is a privacy problem when the Word file is a contract, a resume, a financial report, or anything with personal information in it. LuraPDF is structurally different: mammoth.js parses your .docx file locally, renders the content to a browser canvas, and pdf-lib encodes the result as a PDF — entirely inside your browser tab, with no file data crossing the network.
How to convert Word to PDF online
Who uses LuraPDF Word to PDF
Word to PDF is one of the most common document tasks in every profession. Here are the workflows it unlocks.
Submit university assignments
Most universities require PDF submissions to prevent editing after submission and ensure consistent display across marking systems. Convert your Word assignment before upload.
Issue invoices and quotes
Send invoices as PDF so clients cannot accidentally or intentionally edit figures. A locked PDF looks more professional than an editable .docx attachment.
Finalize legal documents
Contracts and agreements are distributed as PDF after the final revision round. Converting to PDF signals that the document is ready for signature and should not be changed.
Consistent printing
Word documents print differently depending on the printer driver, page margins, and paper size settings. PDF eliminates those variables — the page breaks and layout you see in the browser are exactly what prints.
Archive documents
PDF is a better long-term archive format than .docx. The content and layout are self-contained — no dependency on Word versions, fonts, or linked objects that may break years later.
Why convert Word to PDF
PDF is the universal delivery format. Here is what you gain when you convert your Word document before sharing.
- PDF renders identically on every operating system, browser, and printer — no broken layouts from missing fonts or different default margins.
- PDF files cannot be accidentally edited by the recipient — the content is locked for the reader's viewing, not their revision.
- PDF is universally accepted by portals, submission systems, email servers, and document signing platforms that may not support .docx.
- Embedded fonts in the PDF ensure your typography is exact even if the recipient does not have your fonts installed.
- PDF files are generally smaller than equivalent .docx files with the same images, because PDF compression is more efficient.
- Converting to PDF before archiving ensures the document will render correctly in future software environments without Word version dependency.
How LuraPDF converts Word to PDF
LuraPDF uses mammoth.js to parse your .docx or .doc file inside the browser. Mammoth reads the Open XML structure, extracts paragraph runs with their formatting attributes (bold, italic, font, size, color), headings with their style levels, table cell content and spanning, and inline images encoded as base64 streams. This structured content is then handed to a layout engine that positions elements on a PDF page using pdf-lib. Each paragraph maps to a PDF text object with the correct font and size; each table row maps to positioned text objects within cell boundaries.
Fonts are handled by subsetting: only the glyph outlines for characters actually present in your document are embedded in the PDF output. This keeps file size manageable while ensuring exact rendering. Images from the .docx are decoded from their base64 representation and embedded as PDF image streams. The final PDF is assembled in browser memory and saved to your device. No data leaves the browser — the mammoth.js parsing, layout calculation, and pdf-lib encoding all run in a single browser tab.

Tips for clean Word to PDF conversion
Most Word documents convert cleanly, but a few preparation steps prevent common issues. Apply these tips before converting.
- Tip 1:
Use built-in Word heading styles (Heading 1, Heading 2) rather than manually bolded large text — they convert to proper PDF heading structure.
- Tip 2:
Embed images at the final resolution you need — downscaling a large image in Word and then exporting to PDF still embeds the large original. Resize before inserting.
- Tip 3:
Avoid Word-exclusive features like Smart Art, embedded Excel charts, or ActiveX controls — these do not transfer to PDF via mammoth.js.
- Tip 4:
Check the page size setting in your Word document before converting — the PDF will use the same page dimensions.
- Tip 5:
Track changes should be accepted or rejected before converting — only the accepted state of the document appears in the PDF output.
- Tip 6:
For a PDF that recipients cannot print or copy, add password protection after conversion using the Protect PDF tool.
Frequently Asked Questions
How does the quality compare to Microsoft Word's built-in Save as PDF?
For standard documents with common fonts, headings, and simple tables, the output quality is comparable. Microsoft Word's native export has an advantage with complex features like SmartArt, embedded charts, and custom styles because it has full access to Word's rendering engine. LuraPDF via mammoth.js handles the most common document structures very well.
Is .doc (legacy Word format) supported?
Yes. Both .doc (Word 97-2003 binary format) and .docx (Office 2007+ Open XML format) are accepted. Mammoth.js handles both formats. Note that very old or unusual .doc files with embedded OLE objects may not convert completely.
Are fonts embedded in the PDF output?
Yes. Standard fonts used in your document are subsetted and embedded in the PDF. Recipients see your intended typeface without needing to install fonts on their device.
Are tables preserved in the output?
Yes. Word tables are detected and converted to positioned PDF text objects that maintain the tabular structure. Simple tables with regular rows and columns convert accurately. Complex merged-cell tables may require minor visual cleanup.
Are images preserved in the output?
Yes. Inline images embedded in the Word document are extracted from the .docx archive and re-embedded in the PDF as image streams at their original resolution.
Do Track Changes show up in the PDF?
No. Only the accepted state of the document appears in the output. Tracked changes, comment balloons, and revision marks are not rendered in the PDF. Accept or reject all changes in Word before converting if you want a specific version exported.
Are headers and footers preserved?
Yes. Header and footer content from your Word document is extracted and placed at the top and bottom of each PDF page at the correct margin position.
Will there be a watermark on the output?
No. LuraPDF never adds a watermark, branding, or footer to your output PDF. The file is yours, clean. There is no premium tier that removes branding because there is no branding.
Can I convert multiple Word files at once?
The Word to PDF tool converts one file at a time. For multiple files, run them sequentially — the tool resets between files without needing a page reload.
Can I password-protect the output PDF?
Not directly in this tool, but it is a two-step process: convert Word to PDF here, then run the resulting PDF through the Protect PDF tool to add a password and set permissions (print, copy, edit restrictions).
