How to Convert Word to PDF

Turning Word and Excel into PDF

Word and Excel files are easy to edit and hard to share. Send a .docx to someone without Word, or open it on a phone, and the layout shifts — fonts change, tables move, and the document you wrote is not the document they see. A PDF fixes that: it looks the same everywhere, on every device, and it cannot be edited by accident. Converting Office files to PDF is the step between writing and sharing, and this tool does it in your browser.

Word files (.docx) are read with mammoth.js, and spreadsheets (.xlsx, .xls, .csv) with SheetJS; the PDF itself is built with jsPDF. The result is a real PDF with selectable text — not a picture of the document. From a Word file, headings, paragraphs, bold and italic, lists, tables, and images all carry over. From a spreadsheet, each sheet becomes one table, with the first row as the header, and each sheet becomes its own section, in order. You can convert up to 20 files at once, 100 MB in total.

The honest limit is the layout. It can shift. Page breaks may fall in different places, the fonts are the standard PDF fonts rather than the ones in your Word file, and a very wide spreadsheet becomes small text as it squeezes onto an A4 page. For reading, sharing, and printing, the result is a correct PDF. For a layout that must look exactly the same, keep the original Office file — the PDF is for distribution, not for pixel-perfect reproduction. Two formats are not supported at all: PowerPoint (.pptx) cannot be converted, and old .doc files (not .docx) must be saved as .docx first.

A few practical tips. Check the PDF after converting, especially the first and last pages, where page breaks cause the most surprises. If a spreadsheet is very wide, consider splitting it into two sheets before converting, or accept the small text and print it on A3. If a Word document has a complex table, check the table in the PDF — most tables convert cleanly, but a table with merged cells can shift. And keep your originals: converting is non-destructive, but the Office file is the one you edit, and the PDF is the one you send.

It also helps to know what converts well and what does not. A simple Word document — headings, paragraphs, a few tables, a few pictures — converts cleanly almost every time. A document with complex formatting — text boxes, floating images, footnotes, headers and footers on every page — will convert, but the pieces may land in different places, because a PDF page is a fixed sheet and a Word page is a flow of text that re-flows as it goes. A spreadsheet with a few columns converts cleanly; a spreadsheet with twenty columns becomes small text, because the whole table must fit the width of one page. If the table matters more than the page, print it on a larger page or split it. And a file with tracked changes or comments will convert the visible text — the comments themselves do not carry over, so resolve them before you convert.

One more practical note: the PDF you download is yours to keep, but it is a snapshot, not a living document. If the Word file changes next week, convert it again — the PDF does not update itself. Keep the Office file as the master copy and the PDF as the version you send out, and name the PDF clearly so you know which version it came from. A file called report-final.pdf is easier to trust than a file called document.pdf, and a date in the name — report-2026-11-10.pdf — tells you at a glance whether it is the latest one.

Everything runs in your browser. Your files are never uploaded to a server, so a contract, a report, or a salary sheet stays on your device. There is no account, no daily limit, and no watermark. Open the tool, drop your Office files, and download real PDFs.

How to use this tool

1. 1Drop a Word (.docx) or spreadsheet (.xlsx, .xls, .csv) file onto the Office to PDF page — up to 20 files, 100 MB in total.
2. 2Press Convert to PDF and wait while the file is read and rebuilt.
3. 3Download the PDF and open it.
4. 4Check the layout: page breaks may differ, and very wide spreadsheets become small text.
5. 5If the layout must look exactly the same, keep the original Office file — the PDF is for reading, sharing, and printing.
