Your document is laid out by this browser and saved as a PDF, without being uploaded. Simple documents come out close to identical; complex layouts and unusual fonts can shift, and the page says where.

Files are not uploaded - everything happens in your browser.
Your browser is already a capable layout engine - it lays out web pages for a living. This tool reads the .docx, turns its contents into HTML and CSS that reproduce the document, lets the browser lay that out at the real page width, and then draws each page onto a canvas and places it in a PDF.
That design has one clear advantage and one clear cost. The advantage is that nothing is uploaded: your CV, contract or letter stays on your device. The cost is that the PDF contains pictures of pages, so the text in it is not selectable or searchable.
If you have Word on the same machine, its own "Save as PDF" will always be more faithful, because it knows the document model. This tool exists for the times you do not: a borrowed computer, a phone, a Linux laptop, or simply an unwillingness to upload the document to someone else's server.
Paragraphs, headings, bold and italic, bullet and numbered lists, line and paragraph spacing, tables with borders, embedded pictures, page size and margins, and left, right, centre and justified alignment all come across reliably.
That covers most real documents: letters, CVs, essays, invoices, minutes, school assignments, reports. For these, the PDF is close enough to the original that nobody will notice the difference.
Right-to-left text, including Arabic, is laid out correctly, because the browser handles bidirectional text properly. Devanagari and Cyrillic are drawn with whichever matching font your device has installed.
Fonts are the main source of difference. A .docx names the fonts it wants but does not usually contain them. If your device has no Calibri, the browser substitutes something else, and a substituted font has different letter widths - so lines break in slightly different places, and a document that filled exactly two pages might spill onto a third.
Field codes are the second source. Page numbers, a table of contents, cross-references and dates are instructions that Word evaluates when it opens the file. We cannot evaluate them, so you get the text that was there when the document was last saved in Word. Usually right; occasionally a page number that no longer matches.
Beyond that: text boxes and shapes positioned absolutely, text wrapped tightly around images, columns, footnotes, tracked changes, comments and embedded objects such as charts and equations are all either approximated or left out. The honest summary is that the simpler the document, the better the result.
Because the pages are drawn rather than described, resolution matters. At 150 dpi the pages look clean on screen and print acceptably. At 200 or 300 dpi printed text is crisper, and the file is correspondingly larger.
A ten-page document at 150 dpi lands at roughly one to two megabytes. The same document at 300 dpi can be four times that. For something you are emailing, 150 dpi is almost always the right answer.
If the result is still too large, PDF Compressor will reduce it further, and for a document that is going to be read on screen you can drop to 120 dpi without it looking wrong.
The modern .docx format is a ZIP of XML files, which can be read with a reasonable amount of code. The old binary .doc format from before 2007 is an entirely different thing: a compound binary document whose structure needs far more code than belongs in a web page.
So .doc files are refused with a clear message rather than being half-converted. Open the file in Word, Google Docs or LibreOffice and save it as .docx first, and this tool will handle it.
The same applies to .odt, .rtf and Apple Pages documents. Any of those programs will export .docx, which is the common ground.
There are two routes. Word's own export produces a PDF with real text, and is the best option when you have Word to hand. Failing that, convert here and then run OCR PDF on the result: it recognises the words in the page pictures and adds an invisible text layer, which makes the PDF searchable.
OCR is not free of errors, so for anything legal or financial, prefer Word's own export. We would rather point you to a better tool than pretend this one does something it does not.
Going the other way, PDF to Word converts a PDF into an editable document, with its own trade-offs explained on that page.
Open the PDF and look at the last page. Pagination is where substituted fonts show up first, and a CV that was a tidy two pages in Word occasionally gains three lines on a third page. If it has, shortening a paragraph in the document is quicker than fighting the layout.
Check anything that was a field: page numbers, a table of contents, a date that updates itself. Those keep the values Word last saved, so a document edited elsewhere and never re-saved can show stale numbers.
Finally, check the tables. Wide tables that fitted the page in Word can wrap differently once a font is substituted, and that is easier to fix in the document than in the PDF. None of these are common, but all three take ten seconds to confirm and save sending the wrong file to someone who matters.
Choose the .docx here and press Convert. The PDF is built in your browser and downloads straight away.
Usually very close. Differences come from fonts your device does not have, and from field codes such as page numbers that only Word can recalculate.
No. The pages are drawn as pictures. Use Word's own "Save as PDF" for searchable text, or run OCR PDF on the result.
Not directly. Open it in Word, Google Docs or LibreOffice and save it as .docx first.
A substituted font has different letter widths, so lines break in slightly different places. Installing the font the document asks for fixes it.
No. It is read and laid out inside your browser. Nothing is sent to a server.
Yes, both. Tables with borders and embedded pictures are reproduced; text boxes and tightly wrapped text are the weak spots.
