How to convert Office files to PDF
Most Office-to-PDF tools are really file upload services: your document goes to a server, gets converted there, and comes back. This tool does the whole job in your browser. A Word document (.docx) is read with mammoth.js, a spreadsheet (.xlsx, .xls, .csv) is read with SheetJS, and the PDF is built on the spot with jsPDF. Nothing is uploaded, and the result is a real PDF with selectable text — not a picture of your document.
Word files keep their structure: headings, paragraphs, bold and italic text, lists, tables, and images all come through. Spreadsheets become one table per sheet, with the first row as the table header. If your spreadsheet has several sheets, each one gets its own section in the PDF, in order.
One honest limitation: the layout can shift. Word and Excel render documents with their own engines, and this tool rebuilds the layout from the content — page breaks land in different places, fonts are the PDF standard set, and very wide spreadsheets get small text. For reading, sharing, and printing, the result is a proper PDF. For a document that must look exactly like the original, keep the Office file. PowerPoint (.pptx) is not supported at all: converting slides needs a server, and this tool runs entirely in your browser. Old .doc files (not .docx) are not supported either — save them as .docx first.

Frequently asked questions
Will the PDF look exactly like the original?
No — and this is the honest trade-off. The tool rebuilds the layout from the document content: headings, text, tables, and images come through, but page breaks and spacing can shift, and the PDF uses standard fonts. For reading, sharing, and printing it is a proper PDF; for a pixel-perfect copy, keep the Office file.
Can I convert PowerPoint (.pptx)?
No. Converting slides needs a server-side Office engine, and this tool runs entirely in your browser with no server. PowerPoint files are rejected with a clear message.
What about old .doc files?
Old .doc files (before .docx) are not supported. Open the file in Word or LibreOffice, save it as .docx, then convert it here.
What happens to my Excel sheets?
Each sheet becomes its own table in the PDF, in order, with the first row as the table header. Empty sheets are skipped. Very wide sheets get small text so all columns fit on the page.
Is my document uploaded anywhere?
No. The file is read and converted in your browser tab, and the PDF is built there too. Nothing leaves your device.
