Frequently asked questions
Can I convert PDF back to ODT for editing?
Yes, but with caveats. LibreOffice can import PDFs as editable documents, and online converters also do this. Complex layouts (multi-column, tables) often don't convert cleanly. PDF-to-ODT is approximate; the more complex the document, the more manual cleanup is needed.
Which is better for legal and official documents?
PDF — specifically PDF/A for archival. PDF/A embeds all fonts, removes JavaScript, and creates a self-contained document suitable for long-term archiving and legal submission. ODT is not accepted by most courts or government agencies.
