Drop your Word files (.docx) here, or click to select

Supported formats: .docx / multiple files supported
Your PDF keeps the exact Word layout — page size, margins, fonts, tables, images and page breaks. An invisible text layer is added on top, so you can still select, copy and search the text.
What the Word to PDF converter (.docx to PDF) can do
This free online tool converts Word documents (.docx) to PDF entirely inside your browser. You can batch-convert several files at once and choose whether to merge them into a single PDF or export one PDF per file. Nothing you add is ever uploaded.
Supported Word file format (.docx)
Supports .docx files from Word 2007 and later. For legacy .doc files, re-save them as .docx in Word first. You can add many files at once in a single batch.
Your PDF looks exactly like the Word document
Page size, margins, fonts, text size, alignment, line spacing, table borders, embedded images and page breaks are reproduced exactly as Word displays them, including headers and footers — close to what Word`s own "Save as PDF" produces.
Pixel-perfect look, and the text stays selectable and searchable
Each page keeps exactly what Word draws, with the document text laid over it invisibly. You get Word's layout untouched while still being able to copy text out of the PDF or find it with Ctrl+F (⌘F on Mac). Expect a few hundred KB per page.
How to batch convert multiple Word files to PDF in 3 steps
- Drag and drop your .docx files, or click to select several at once
- Choose "Merge into one PDF" or "One PDF per file" (when merging, drag the rows to set the page order)
- Press convert and download the result — individually, or all at once as a ZIP when exporting separate files
Choose between merging into one PDF and exporting one PDF per file
Sometimes you want several Word documents bound into a single PDF; other times you want to keep one file per document. This converter supports both, and the choice appears as soon as you add two or more files.
Combine multiple Word files into a single PDF
Chapters of a manuscript, weekly reports collected into a month, or a full contract package are joined into one PDF in the order shown in the list. Drag the rows to rearrange them; each document starts on a new page. No separate merging step afterwards.
Batch convert each Word file into its own PDF
This is the default. Every .docx you add is exported as an independent PDF that you can download per file, or grab together with "Download all as ZIP". It replaces repeating Word's Save As for every single document.
Your Word documents are never sent anywhere
How the conversion stays inside your browser
Parsing the .docx and generating the PDF both run as JavaScript in your own browser. The contents of your files are never transmitted to sakutto's servers, and there is no upload step at all.
Why it is safe for contracts, résumés, and confidential files
Because no network request carries your content, you can safely convert confidential proposals, contracts, résumés, and meeting minutes. Close the browser tab after converting and nothing remains.
When converting .docx to PDF is useful
- Submitting documents: turn résumés, CVs, and application forms into PDF so the layout cannot shift on the recipient's machine
- Binding several drafts together: merge chapter-by-chapter proposals or manuals into one PDF for distribution
- Processing many files at once: add a folder's worth of reports or minutes and convert them all into individual PDFs in one pass
- Sharing with people who do not have Word: convert .docx to PDF so it opens on any computer or phone

Why Word to PDF Converter on sakutto is safe
Many online tools upload your files to external servers for processing. This tool never sends your Word files (.docx) to any server — everything is processed entirely in your browser.
* Some AI-powered tools require server-side processing. Tools that send data to a server will always notify you beforehand.
| Comparison | Typical online tools | sakutto |
|---|---|---|
| Where data is sent | Uploaded to external servers | Nowhere — processed in your browser |
| Data leak risk | Risk during transfer and server storage | No risk — no network transfer occurs |
| External traffic | File data travels over the internet | No file data appears in network logs |
| Offline use | Not possible (server required) | Works offline after initial load |
How browser-based processing works
- WebAssembly (WASM): Processes Word files (.docx) in your browser at near-native speed. No server communication occurs.
- Web Workers: Runs on a background thread separate from the main thread, so your browser stays responsive during processing.
- After processing, your browser automatically frees the data from memory. No Word files (.docx) remains outside your device.
For IT security teams: How to verify
You can verify that sakutto never sends your Word files (.docx) externally by checking the Network tab in your browser's DevTools while using the tool. You'll see that no requests involving your Word files (.docx) are made. This can also serve as documentation for your IT security team.
Word to PDF converter FAQ
Can I combine several Word files into one PDF?
Yes. Once you add two or more files you can choose "Merge into one PDF" or "One PDF per file". Merging joins the documents in the listed order, and dragging the rows changes that order.
Can I convert each Word file into its own separate PDF instead?
Yes, and that is the default. Each file is exported as its own PDF, downloadable individually or together as a ZIP archive.
Does it support the older .doc format?
Only .docx (Word 2007 and later) is supported. Re-save a legacy .doc file as .docx in Word first, then convert it here.
Is the Word layout preserved in the PDF?
Yes. Page size, margins, fonts, tables, images and page breaks are reproduced exactly as Word shows them, and an invisible text layer keeps the text selectable, copyable and searchable.
Are my documents or the generated PDFs stored on a server?
No. The whole conversion happens in your browser, so neither the .docx files you add nor the PDFs that are produced are ever sent to or stored on sakutto's servers.
