Quick Verdict
Use PDF when…
Use PDF for distributing final documents — invoices, contracts, reports, forms, academic papers. PDF ensures the recipient sees exactly what you designed, with no font substitution or layout shift.
Use ODT when…
Use ODT for working documents that need to be edited — drafts, templates, collaborative writing. ODT is fully editable in LibreOffice (free), and an open standard less tied to Microsoft than DOCX.

| Opens in browsers | Yes (built-in PDF viewer) | No (requires LibreOffice or conversion) |
| Track changes | Not natively | Yes (LibreOffice Writer) |
| Printing fidelity | Exact | Good but printer-dependent |

Frequently asked questions
Can LibreOffice open and edit PDF files?
LibreOffice Draw can open PDF files and let you edit text and objects, but the result is often imperfect — PDF's fixed layout doesn't map cleanly to editable objects. For minor edits, it works; for significant re-editing of a PDF, you're better off finding the original source document (ODT, DOCX) and editing that, then re-exporting to PDF.
Is ODT compatible with Microsoft Word?
Microsoft Word can open and save ODT files, but compatibility is imperfect — complex formatting, styles, and features may not translate exactly between ODT and DOCX. For documents shared primarily with Word users, DOCX is the safer format. For documents you control and edit in LibreOffice, ODT preserves more features accurately.
How do I convert ODT to PDF?
LibreOffice: File → Export as PDF. Command line: `libreoffice --headless --convert-to pdf input.odt`. On Linux servers, this works without a display. Pandoc: `pandoc input.odt -o output.pdf` (requires a LaTeX installation). Online converters (CloudConvert, Smallpdf) handle ODT to PDF for files you can upload.
