The formats
Word and PDF at a glance
What is a Word file?
DOCX is the document format Microsoft Word has used since 2007. It stores editable text with styles, tables, images, comments, and tracked changes, and it's what most people mean when they ask for a Word file. It opens in Microsoft Word, Google Docs, Apple Pages, LibreOffice Writer, WPS Office, and the Word app on phones.
What is a PDF file?
PDF is the standard format for sharing documents that should look the same everywhere. It fixes the layout, fonts, and images of every page, which is great for reading and printing but makes editing hard. A PDF can contain real text or only scanned pictures of pages. It opens in every browser, Adobe Acrobat Reader, macOS Preview, Microsoft Edge on Windows, phones, and Google Drive.
Good to know
What changes when you convert Word to PDF
- LibreOffice lays out the pages, so text, images, tables, headers, and footers look like they do in the original.
- Fonts that aren't built in are replaced with similar ones, which can shift line breaks slightly.
- The first conversion downloads LibreOffice compiled to WebAssembly (77 MB). It's cached, so later visits start quickly.
- Chinese, Japanese, and Korean text may appear in a fallback font.
- Password-protected documents can't be converted.
- It works best on a computer, because LibreOffice needs a lot of memory.
FAQ
Questions, answered
Are fonts preserved when Word is converted to PDF?
Common fonts and the fonts bundled with the converter are preserved closely. A document that uses a font unavailable in the browser may use a metrically similar substitute, which can change line and page breaks.
Is this Word to PDF converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with LibreOffice compiled to WebAssembly, so your files never leave your device. Once the page and the engine have loaded, it even works offline.
Will my PDF look like the original Word file?
In most cases, yes. LibreOffice lays out every page, including fonts, images, tables, headers, and footers. If the document uses fonts that aren't built in, similar fonts are used, which can shift line breaks slightly.
Why is there a download the first time?
The conversion uses LibreOffice, the open-source office suite, compiled to run inside your browser. It's about 77 MB, downloads once from Ethical Tube's own server, and is cached for next time. Your documents are never uploaded.
Can I convert several Word files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each PDF file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
It works in Chrome, Edge, Firefox, and Safari, but it's built for computers. LibreOffice needs about 1 GB of memory, which many phones can't spare.
What can open a PDF file?
Every browser, Adobe Acrobat Reader, macOS Preview, Microsoft Edge on Windows, phones, and Google Drive.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle documents with hundreds of pages.
