Why convert office files to PDF
Editable office formats are best while you are working. PDF is better when the file is ready to submit, print, archive, or share with someone who should see a fixed layout.
OpenDocument files
Use ODT to PDF for LibreOffice Writer and OpenOffice text documents. Use ODS to PDF for Calc spreadsheets. Use ODP to PDF when a presentation deck needs a stable handout or upload file.
Microsoft Office files
Use DOCX to PDF for Word documents, XLSX to PDF for spreadsheets, and PPTX to PDF for slide decks. Review page breaks, fonts, tables, charts, and image placement after conversion.
Keep the editable source
Use PDF for final delivery and keep the original office file for future changes. That gives you a stable submitted copy and an editable master.
