Why Sending a DOCX Is Riskier Than You Think
A Word document looks perfect on your screen. You have spent time getting the fonts right, the spacing consistent, the page breaks exactly where they should be. Then the person on the other end opens it and sees something completely different — headings in the wrong font, paragraphs that have reflowed onto different pages, a table that has overflowed its borders, or a cover page that has shifted entirely out of place.
This is not a fluke. It is how Word documents work. A DOCX file does not record exactly how a document looks — it records instructions for how it should be rendered, and then hands off the actual rendering to whatever software opens it. Different versions of Word, Google Docs, LibreOffice, and Pages on Mac all render the same DOCX file differently. Even two installations of the same Word version can produce different output if one is missing a font the document uses.
Converting to PDF before sending eliminates this problem entirely. A PDF captures exactly what you see on your screen and locks it in place. The recipient sees the same document regardless of what device, operating system, or software they use to open it.
Four Common Problems That PDF Solves
Font substitution
If the recipient doesn't have your font installed, their software substitutes a different one — shifting text, breaking layouts, and changing line lengths throughout the document.
Page breaks shifting
Even a minor font or margin difference can push content onto different pages, separating headings from their sections or splitting tables across page breaks.
Accidental edits
A DOCX file can be modified by anyone who opens it. A PDF cannot be accidentally changed — your content stays exactly as you wrote it.
Software dependency
Opening a DOCX requires compatible software. A PDF opens natively on every device — Windows, Mac, iPhone, Android — without any additional app.
The Fastest Method: Convert Online
If you do not have Microsoft Word installed, or you simply want the quickest path with no software to configure, an online converter handles the job in seconds from any device.
-
1Go to Convixy Word to PDF and upload your DOC or DOCX file by dragging it onto the page or clicking to browse your device.
-
2The converter processes your file on the server, preserving your fonts, layout, images, tables and formatting in the output PDF.
-
3Download your PDF. The file is deleted from the server immediately after — nothing is stored or shared.
How to Convert in Microsoft Word on Windows
If you have Microsoft Word installed, the built-in export function is the most reliable method — it uses the same rendering engine that created the document, so the output is as accurate as it gets.
Method 1: Export to PDF (recommended)
Open your document in Word. Go to File → Export → Create PDF/XPS Document, then click Create PDF/XPS. Choose where to save the file and click Publish. Before clicking Publish, you can click Options to control exactly what gets included — specific page ranges, document properties, or accessibility tags.
Method 2: Save As PDF
Go to File → Save As, click the file type dropdown, and select PDF. This is quicker but gives you slightly fewer options than the Export route. Both methods produce identical quality output.
Method 3: Print to PDF
Press Ctrl + P, change the printer to Microsoft Print to PDF, and click Print. This works as a fallback when the other methods are unavailable, but it bypasses some of Word's PDF export optimisations — use Export or Save As when possible.
How to Convert in Microsoft Word on Mac
Word for Mac handles PDF export slightly differently from the Windows version, but the result is equally reliable.
-
1Open your document in Word for Mac and go to File → Save As.
-
2In the format dropdown, select PDF. Name your file and choose where to save it.
-
3Click Export. Word generates the PDF and saves it to your chosen location.
Alternatively, go to File → Print, click the PDF dropdown in the bottom-left corner of the print dialog, and select Save as PDF. This route gives you access to page range selection if you only need part of the document.
How to Convert Using Google Docs
If your document is stored in Google Drive or you prefer working in Google Docs, the export path is straightforward. Open the document in Google Docs, go to File → Download → PDF Document (.pdf). Google Docs exports the document as a PDF and downloads it to your device automatically.
How to Convert on iPhone
If you have the Microsoft Word app installed on your iPhone, you can export directly from within it. Open your document, tap the three-dot menu in the top-right corner, select Export, and choose PDF. Word generates the PDF and gives you sharing options — save to Files, send via email, or share to another app.
If you do not have the Word app, the quickest method is to use Convixy Word to PDF in your iPhone's browser. Upload the file from your Files app or iCloud Drive, convert, and download — the entire process takes under a minute without installing anything.
How to Convert on Android
The Microsoft Word app for Android supports PDF export the same way as iOS — open the document, tap the menu, select Export, and choose PDF. For Android devices without the Word app, a browser-based converter is the most practical option. Open Convixy in Chrome, upload your DOCX from your device storage, and download the resulting PDF directly to your phone.

Before You Convert: A Quick Checklist
-
01Accept or reject all tracked changes. Any Track Changes markup in your document will appear in the PDF exactly as it looks on screen. If you have revision marks showing, accept or reject them all before converting so the PDF shows only the clean final text.
-
02Check your page breaks. Scroll through the document at 100% zoom and confirm that section headings, tables, and figures are sitting on the correct pages. What you see before converting is what the PDF will show.
-
03Embed your fonts. In Word for Windows, go to File → Options → Save and check Embed fonts in the file before exporting. This ensures the conversion engine has access to every font used, including custom or purchased typefaces.
-
04Remove personal metadata if needed. Word documents embed author name, revision history and other metadata. If you are sharing the PDF externally and want to remove this, go to File → Info → Check for Issues → Inspect Document before converting.
-
05Compress after converting if the file is large. Documents with many high-resolution images can produce large PDFs. Run the output through a PDF compressor to reduce the size before emailing or uploading — typically 40–70% smaller with no visible quality difference on screen.
When to Keep the DOCX Instead
PDF is the right format for sharing a finished document, but there are situations where keeping it as a DOCX is the correct choice. If you are sending the document to someone who needs to edit it, add comments, or continue building on it, a DOCX is what they need. PDF is a read-only presentation format — editing within it is possible but cumbersome compared to working directly in Word.
The standard professional workflow is to keep the DOCX as your working file and produce a PDF only when the document is finished and ready to share, submit, or archive. Think of the PDF as the output and the DOCX as the source. If you need to make changes later, edit the DOCX and generate a new PDF — never try to edit the PDF back into a working document if the original source is available.
