Open a Word document without Word, check it looks right, and save it as a PDF. The document is opened on your own device, so a contract or a CV never goes anywhere.
Drop in a .docx file. It is unzipped and laid out in this tab, so nothing is sent anywhere, and you can read it even if you have no Word on this device.
The preview is the finished layout, page by page. Look at where the pages break and whether any table has shifted before you go further.
The button opens your browser's print window. Choose Save as PDF as the destination and set margins to None, because the document already carries its own.
The hard part of this job has never been reading the file. A .docx is a zip of XML and its structure is documented. The hard part is deciding where every line, table row and page ends, which is the thing Word spends most of its effort on.
A browser already does exactly that work, for every page you have ever printed. Laying the document out with the browser's own engine and then printing means the pagination is computed by software that does nothing else all day, and the result is a PDF with real selectable text rather than a picture of each page.
The one thing that genuinely moves a page break is a missing font. Word documents usually ask for Calibri, which almost no device outside Windows has, and a substitute with different letter widths changes where every line wraps and therefore where the pages divide. We ship a font with the same letter widths, so the breaks land where the document intended even though the shapes are slightly different.
No. The work happens inside this tab, on your own machine. Open your browser's network tab while you use the tool, there is no request carrying your file.
Practical limits depend on the tool, browser and available device memory. Large files can fail even when no explicit limit is shown. Keep an original and use a smaller job if this device cannot finish it.
No, and there is no daily limit either. There is nothing to sign up for.
Because the print engine is what produces the correct pagination. Choosing Save as PDF there gives you a proper text PDF, not an image of the pages.
No. The binary format Word used before 2007 is a different thing entirely. Open it in anything that reads it and save it as .docx first.
For letters, CVs, reports and most documents, yes. Text in columns, images that text flows around and very complex tables are where any converter drifts, so check the preview before sending anything that matters.
That is a much harder problem and we do not pretend to do it. A PDF stores placed text rather than paragraphs, so turning one back into an editable document means guessing at the structure, and the guesses are usually wrong.
The document is laid out in the page by reading the .docx structure, and then your browser's own print window does the final step. Choose Save as PDF as the destination and set margins to None, because the document already carries its own. The text in the result is real text, and headers, footers, footnotes and page breaks are drawn where the document put them.
When a document uses Calibri, which most devices do not have, a font with the same letter widths is used so lines wrap in the same places. A notice tells you when that happens.
Only the .docx format opens. An older .doc file needs to be saved as .docx in a program that reads it first. Text in columns, pictures that text wraps around and very complex tables are where any converter can drift from Word, so check the preview page by page before you save.
The Save as PDF choice in the print window is available on computers in current browsers. Some phone browsers do not offer it, in which case use a computer.
