DOC to PDF is on the release list
A real layout engine — the same one that renders the document on screen — draws the document onto fixed-size pages and writes them out as a PDF. That needs a full document rendering engine, so it will run on our servers rather than in your browser. It is next in the queue and it will be free.
Do it now, on your device
No DOC conversion runs on-device yet — but these do
We would rather point you at something that works than at a queue. These conversions run entirely inside your browser right now — no upload, no account, no watermark.
The details
What happens when you convert an office document to PDF
The original binary Word format, from before 2007. Still everywhere, still awkward. A real layout engine — the same one that renders the document on screen — draws the document onto fixed-size pages and writes them out as a PDF. The result is a the portable document format. fixed layout, universal, and the reason everyone can open the file you send them, produced on our conversion servers.
What survives
- The text, which stays selectable and searchable
- The layout, including tables, columns, headers and footers
- Images, charts and embedded fonts
- Page breaks chosen by the author
What changes
- Editing features are gone: there are no tracked changes, comments or styles to change
- Dynamic elements — a linked spreadsheet, a live chart — are frozen as they appeared
- Interactive form fields usually become static text
Where it goes wrong
- A font installed on the author's machine but not yours will be substituted, and the line breaks will move
- Long documents paginate slightly differently on different engines, so check the page count
- A document with tracked changes shows the markup unless the changes are accepted first
Why anyone would do this
A PDF looks the same on every device, which is the difference between a document that is read and one that is retyped.
About the format
The original binary Word format, from before 2007.
A single binary compound file with streams of structured data. A small header identifies the Word version and points at the text, formatting and table streams.
- Where it is good
- Opens in almost any word processor, including very old ones
- Keeps the original layout of documents from the 1990s and 2000s
- A single file with no container around it
- Where it falls short
- Dated and rarely created by anything new
- Larger than the DOCX equivalent
- More fragile — one damaged stream can lose the whole document
- You will find it on
- Legacy systems, old archives, some government portals
The thing people miss
Microsoft kept a hidden converter inside Word for years so that opening a .doc never lost anything.
About the target
The portable document format.
A tree of objects describing pages, fonts, images and scripts, with a cross-reference table and a file trailer. Text and vector graphics are stored separately from the page layout.
- Looks identical on every operating system and every device
- Holds text, images, vector art, forms, signatures and 3D
- Can be locked, compressed, tagged for accessibility and archived as PDF/A

Questions
DOC conversion questions
What actually happens to my DOC file when I convert it to PDF?
A real layout engine — the same one that renders the document on screen — draws the document onto fixed-size pages and writes them out as a PDF. So the DOC file is unpacked, the content is laid out, and the result is written out as PDF. The text, which stays selectable and searchable survives unchanged.
Will converting DOC to PDF reduce the quality?
Partly. Some formatting is approximated because the two formats describe layout differently. The text itself is never re-typed, so no words are lost.
Is my DOC file uploaded to a server?
This particular conversion needs a full document rendering engine, so it is processed on our servers. Your DOC file is deleted automatically within an hour of the download being ready, and it is never opened or reviewed by a person.
Do I need an account or will there be a watermark?
Neither. There is no sign-up step, no email capture and no watermark on the output. The only limits are the ones your own device imposes.
What is the most common mistake people make when converting DOC to PDF?
A font installed on the author's machine but not yours will be substituted, and the line breaks will move
Why would somebody convert DOC to PDF at all?
A PDF looks the same on every device, which is the difference between a document that is read and one that is retyped. In short: opening a document received from an old system
Something most people do not know about DOC?
Microsoft kept a hidden converter inside Word for years so that opening a .doc never lost anything.
