Why PDFcrest
Compared to Adobe Acrobat, ilovePDF, SmallPDF, Zamzar, and Nitro — PDFcrest gives you more for free with zero friction.
Fonts, colors, tables, headers, footers, and images are reproduced closely to your original Word document — the same LibreOffice-based conversion engine used by many professional tools.
Most conversions finish in well under a minute, even for longer documents with images and complex formatting.
No account, no credit card, no watermarks — and no daily limit on how many files you convert.
Works in Safari on iPhone or any Android browser — no app to install, and nothing to configure.
Converts both the legacy Word 97-2003 (.doc) format and the modern Word 2007+ (.docx) format — upload either one and conversion is handled automatically.
All uploads are TLS-encrypted, and your file is deleted from our server as soon as conversion finishes — see exactly how in "How Word to PDF Conversion Works" below.

Use Cases
From job seekers to legal professionals — anyone who needs a document that displays the same everywhere reaches for a PDF.
Convert your CV to PDF before sending it to employers — it prevents accidental edits and keeps your formatting consistent on any recruiter's screen.
Convert contracts, invoices, and proposals to PDF — a format that's widely preferred for signed documents and displays identically across devices.
Convert a dissertation or journal article draft to PDF before submitting it — most institutions require PDF, and citations and footnotes carry over.
Convert to PDF before sending to a printing service — most professional printers require PDF format for consistent colour and layout.
Convert Word documents to PDF for court filings, compliance reports, and NDAs — a fixed format that can't be casually edited after the fact.
Convert annual reports, marketing decks, and client presentations to PDF — sharing a PDF avoids the missing-font issues that can distort a Word file on other machines.
Technical Detail
No black box — this is what actually happens when you click Convert. PDFcrest's server saves your upload, then hands it to unoconv, a well-established open-source tool built on LibreOffice's own document engine, with a single command:
Word to PDF — server-side pipeline (Flask, unoconv):
file = request.files['file'] # your uploaded DOC/DOCX
subprocess.run(['unoconv', '-f', 'pdf',
'-o', output_path, input_path]) # LibreOffice's own DOCX/DOC import
# and PDF export, run headless
os.remove(input_path) # uploaded file deleted right after conversion
LibreOffice's importer reads your document's real structure — paragraph and character styles, tables, embedded images, headers, footers, page margins — and its PDF exporter writes that structure out directly. It's the same open-source conversion engine used inside many other document tools, and it handles the vast majority of Word documents very well. It isn't Microsoft Word itself, though, so documents with unusual fonts, tracked changes, or intricate embedded objects can occasionally shift slightly — worth a quick check before you rely on the output for something like a signed contract.
Once your PDF is ready, you can further compress it to reduce file size or merge it with other PDFs using PDFcrest's other free tools.
