Why convert XLS to PDF?
Convert XLS to PDF to turn an old binary Excel spreadsheet into a clean, fixed-layout document anyone can open and print — no Excel required, and no risk of someone editing your cells or formulas. Your .xls is uploaded over an encrypted HTTPS connection, rendered server-side with LibreOffice exactly as its print settings define, then returned as a PDF and deleted right after. It's free, with no sign-up and no watermark.
- Sharing a legacy .xls file from an older Excel version with someone whose software can't reliably open the format.
- Locking down an invoice, quote or financial report so the numbers and formulas can't be altered after you send it.
- Archiving or attaching a spreadsheet as a print-ready PDF that always looks the same on every device, browser and operating system.
XLS vs PDF
XLS · Legacy Excel Spreadsheet
XLS is the older binary Excel format. Still readable everywhere, but XLSX is the smaller, modern standard.
PDF · Portable Document Format
PDF is the universal format for finished documents — fonts, layout and images are locked in so it looks identical on every device and printer. Perfect for sharing and printing, harder to edit.
XLS to PDF — frequently asked questions
Will my columns and rows stay on the page?
Wide sheets are paginated using the workbook's existing print area and page setup, so columns can split across pages. For the tightest result, open the .xls in Excel first and set a print area or 'Fit to Width' before converting.
Does this handle the old .xls format, not just .xlsx?
Yes. The server uses LibreOffice, which reads the original binary .xls format (Excel 97–2003) directly, so you don't need to re-save it as .xlsx first.
Is my file private?
Your spreadsheet is sent over an encrypted HTTPS connection to our conversion server, converted, and deleted immediately afterward. We don't keep, open or share it, and the PDF has no watermark.
