Why convert XLS to PDF?

Converting from XLS (Microsoft Excel Binary Spreadsheet) to PDF (Portable Document Format) helps you create a universally readable document. XLS and PDF serve different purposes, and converting between them bridges the gap.

XLS vs PDF: technical comparison

XLS (Microsoft Excel Binary Spreadsheet, introduced in 1987) uses None (OLE2 compound binary) compression. PDF (Portable Document Format, introduced in 1993) uses Flate, JPEG, JPEG2000, JBIG2, CCITT for embedded content compression. XLS browser support: None (requires office application). PDF browser support: Universal (built-in PDF viewers in all major browsers).

What happens to quality?

The quality impact depends on the specific settings used during conversion. PDF uses compression that may affect quality depending on the chosen settings.

File size impact

Typical XLS file size: A 10,000-row spreadsheet: ~1-5 MB. Typical PDF file size: A 10-page text document: ~100-300 KB; with images: ~1-10 MB. Expect a dramatic file size reduction — often 5-20x smaller — when converting from uncompressed XLS to PDF.

Common use cases

  • Sharing final documents that should not be accidentally edited
  • Submitting XLS files to systems that require PDF format
  • Converting XLS files to PDF for compatibility with specific applications or workflows
Pro tip

Before converting to PDF, embed all fonts in your XLS document to prevent font substitution issues on the recipient's device. Also review page margins and headers/footers, as they can shift slightly during conversion.
