About This Tool
Word to PDF converts a .docx, .doc or .odt document into a PDF with LibreOffice compiled to WebAssembly, running in your browser tab. Add the file, select Convert to PDF and download the result. Page size, margins, orientation, headers and page numbers all come from the document itself, as there are no layout settings here.
LibreOffice is a large program. Opening this page starts loading it straight away, with a progress panel on screen while it prepares. The engine files add up to roughly 260 MB before any compression, so use a steady connection the first time. Once loaded they are stored in your browser's cache storage, and later visits read them from there unless you clear the site's data.
LibreOffice reads Word formats closely but not identically. It cannot see the fonts installed on your computer: it uses the fonts bundled with it, plus Noto Sans SC for Chinese text, and substitutes anything else, which can shift line and page breaks. There is no password prompt, so a document that needs a password to open must be unlocked in Word first. Files over 50 MB are refused, and a conversion still running after five minutes stops with an error.
The document is converted inside the tab and is not uploaded. Below the main converter, a Batch Word to PDF panel takes several files and converts them one after another, with a ZIP download at the end. Before converting an SOP, batch record or report for review, accept or reject tracked changes and update fields such as the table of contents, then compare the page count of the PDF with the Word file.

How to Use
Open the tool and let it prepare
A progress panel appears as soon as the page loads while the conversion engine starts. The first visit takes longest because the engine has to download.
Add your document
Drag a .docx, .doc or .odt file onto Upload Word Document, or click to browse. One file goes in the main converter at a time.
Select Convert to PDF
The progress bar advances while LibreOffice lays out the pages. You can cancel at any point.
Download and check
Select Download when the success message appears, then look over page breaks, tables and headers in the PDF.
Converting several files
Use the Batch Word to PDF panel: add the documents, select Start batch conversion, then Download all or Download ZIP.
Use Cases
Issuing an approved procedure
Produce the PDF copy of a finalised SOP or work instruction for circulation, so readers see a fixed layout rather than an editable file.
Submitting to a portal that wants PDF
Grant, tender and regulatory portals often accept PDF only. Convert the response document on your own machine before uploading it to the portal yourself.
Opening old .doc files
Turn legacy .doc reports from a shared drive into PDFs that open on any device, without needing a copy of Word.
Sending a CV or cover letter
Lock the layout of a CV before applying, so recruiters see the same line breaks and spacing you saw.
Frequently Asked Questions
Which file types can I convert?
The converter accepts .docx, .doc and .odt files, each up to 50 MB. For spreadsheets and slide decks use Excel to PDF and PowerPoint to PDF.
Why is the first conversion slow?
The tool runs LibreOffice in your browser, and its files total roughly 260 MB before compression. They download when you first open the page and are then kept in your browser's cache storage, so later visits load the engine locally. Clearing site data for this site removes them.
Will the PDF look exactly like my Word document?
Usually close, but check it. LibreOffice lays the document out itself and can only use its bundled fonts, so a font it does not have is replaced and text may wrap differently. Complex text boxes, unusual fields and some Word-only features can also shift.
What does compatibility mode mean?
LibreOffice needs a browser feature called SharedArrayBuffer. If your browser cannot provide it, the tool switches to a simpler converter that handles .docx only and rebuilds the text, headings and tables itself, so the layout will differ more from Word. .doc and .odt files cannot be converted in that mode.
Can I convert a password-protected document?
No. There is no way to enter a password, so open the file in Word, remove the password, save, and convert the saved copy.
Is my document uploaded?
No. The file is read and converted inside the tab on your device. The only things downloaded are the engine files from this site.
