About Legacy Excel Spreadsheet
Binary Excel 97-2003 format.
About Portable Document Format
Predictable layout on every device, strong print fidelity, universal viewers, and support for signatures and forms. Editing is harder than editing a word processor document; reflow, accessibility, and text extraction depend on how the PDF was produced.
Format referenceWhy convert XLS to PDF?
- PDF is more appropriate for the target application, device, or delivery channel than Excel.
- Compatibility is the main reason to convert when another person or service cannot open the source.
- The new format may support a feature the source container does not.
- The result can be reviewed without changing the file that other people still use.
Will quality change?
Text may become editable, but page breaks and spacing can differ from the original. Review the output before sharing it. Keep the source if you may need to adjust the conversion later.

When not to convert
