Convert Word to PDF Online Free
PDF is the go-to format when you need to share a document that looks the same for everyone — no fonts shifting, no layout reflow, no surprises. If you have a Word document and need it as a PDF, here's how to do it free in your browser without installing anything.
How to convert Word to PDF in your browser
- Open the Word to PDF tool.
- Click the upload area or drag your .docx file onto the tool.
- Click Convert to PDF — the tool extracts the text using Mammoth.js and builds the PDF with pdf-lib.
- Your PDF downloads automatically. No upload, no server, no account needed.
What gets converted — and what doesn't
The Irreva Word to PDF converter extracts the text content from your .docx file and lays it out in a clean, readable PDF. All the words, paragraphs, and line breaks come through correctly.
What it doesn't transfer: bold, italic, heading styles, tables, images, columns, and precise font choices. The output uses a standard Helvetica font. For most plain documents — cover letters, notes, reports, summaries — this is fine. For documents where the visual formatting is critical, use Word's own export instead.
When to use Word's built-in PDF export instead
If you need a pixel-accurate PDF — one that looks exactly like the Word document — Microsoft Word's File → Save As → PDF is the right tool. Google Docs' File → Download → PDF works the same way. Both have full access to the document's rendering engine and produce a faithful visual copy.
Irreva's converter is best when you don't have Word or Google Docs handy, when you need a quick plain-text PDF from a document, or when you're processing a document on a device that doesn't have Office installed.
Common questions
- .doc files — not supported. Open in Word or Google Docs and save as .docx first.
- Password-protected .docx — remove the password in Word (File → Info → Protect Document) before converting.
- Large files — up to 50 MB accepted. Very large documents may take a moment.
- Scanned documents — if you have a scanned PDF and need it in Word format, use PDF OCR first, then PDF to Word.
Frequently Asked Questions
Does this tool require Microsoft Word?
No. The conversion runs entirely in your browser using Mammoth.js and pdf-lib. You don't need Word, Google Docs, or any other software installed.
Why doesn't the PDF look like my Word document?
This tool extracts plain text only — formatting like bold, tables, and images doesn't carry over. For a visually accurate PDF, use Word's File → Save As → PDF or Google Docs' download option.
Can I convert .doc files (older Word format)?
No — only .docx (Word 2007 and newer). Open the .doc file in Word or Google Docs and save as .docx before converting.
Is my document uploaded anywhere?
No. Mammoth.js extracts the text locally in your browser and pdf-lib builds the PDF in browser memory. Nothing leaves your device.
The PDF has question marks instead of some characters — why?
Standard PDF fonts don't support every Unicode character. Emojis, special symbols, and some non-Latin characters get replaced with a ? to keep the PDF readable. For full Unicode support, export from Word or Google Docs directly.
