Convert DOCX to PDF Online Free

Word to PDF, with a check before it leaves your hands.

A PDF freezes the page exactly as the recipient will see it: including anything you forgot was there. We scan the document first and let you decide what goes out.

What each format does to your document.

We converted one source document into every major output format and measured the file that came out. The source was a 37.4 KB DOCX with headings, bold and italic text, a table, numbered and bulleted lists, and one embedded image.

289%PDF, the largest output
166%RTF, bloated but portable
3%Markdown and TXT, image dropped

.dbk Markup 3.5 KB · 9% Structured Text, structure Technical documentation only
Plain text is tiny because the image goesMarkdown and TXT both came out at 3% of the source, against 100% for DOCX: the embedded image is the bulk of the file, and neither format can hold it.
PDF pays for a fixed pageAt 289% of the source, PDF was the largest output. That is the cost of fixing the layout, fonts and image into a page that looks identical everywhere.
RTF is the surpriseIt keeps formatting but grew to 166% of the DOCX, so it is only worth using when the receiving program cannot read anything better.

Sizes are from one representative document converted with Pandoc and LibreOffice. Your own files will differ, especially with more images, but the relative ordering holds.

~/is-your-pdf-really-text

Why PDF to Word is the hard direction.

A PDF has no paragraphs. It stores “draw these glyphs at x, y in this font”, often one word or one line at a time, and a scanned page stores only a picture. Drop any PDF to see which kind you have and what its page instructions look like.

~/fonts-go-inside

Your brand font only survives if it's packed in.

A Word file just names its fonts and hopes the next computer has them. A PDF can carry the fonts inside it, so the page looks the same everywhere. We embed only the characters you actually used, which usually adds 20-60 KB.

The font travels inside the PDF, so the headline keeps its weight, spacing and line breaks on any computer.
~/a4-or-letter

Sending abroad? Check the paper size.

The PDF keeps whatever page size Word used. The US and Canada print on Letter; almost everywhere else uses A4. Print one on the other and the printer either shrinks the page or cuts off an edge.

Frequently Asked Questions

Is converting DOCX to PDF free?

Yes, DOCX to PDF conversion is completely free with no signup, no watermark, and no usage limit. Convert as many files as you need.

Are my files uploaded to a server?

Your DOCX to PDF file is sent over an encrypted connection to our servers, converted, and returned to you. Files are processed only to perform the conversion and are not stored or retained afterward, so they are removed automatically once your download is ready.

How long does DOCX to PDF conversion take?

Most DOCX to PDF conversions finish in under a minute. Expect a longer wait for a bigger file. It runs on your own device either way, with no account step in front of it.

Will the conversion reduce file quality?

It depends on the pair. Lossless gives you the same thing back, byte for byte. Lossy makes the file smaller and costs you something, though whether you can actually see or hear it is another question.

Does this work on mobile devices?

Yes. The DOCX to PDF converter works on phones, tablets, and desktops in any modern browser including Chrome, Safari, Firefox, and Edge.
