How to Convert ODT to PDF

ODT (OpenDocument Text) is the default format for LibreOffice Writer and OpenOffice. While ODT is excellent for editing, PDF is the universal standard for sharing documents — it preserves layout, fonts, and formatting across every device regardless of what software the recipient has. Converting ODT to PDF is a one-click operation in LibreOffice, or instant with an online tool.

Step-by-step instructions

  1. 1

    Upload your ODT file

    Select your .odt file. ODT documents from LibreOffice Writer, Apache OpenOffice, or Google Docs export all convert cleanly to PDF.

    Go to converter
  2. 2

    Choose PDF as the output format

    Select PDF. The converter renders the document to PDF exactly as it would appear in LibreOffice — fonts embedded, images included, formatting preserved.

  3. 3

    Download the PDF

    The resulting PDF is a fixed-layout document that looks identical on any device. Share it via email, upload to a form portal, or print it — the layout will never shift.

Why convert ODT to PDF?

ODT is the open-standard document format; PDF is the open-standard presentation format. Converting ODT to PDF means your document will look exactly right on any device, without requiring LibreOffice.

Your files never leave your device

FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.

Frequently asked questions

Will ODT to PDF preserve my fonts and formatting?
Yes, with caveats. If your ODT uses common system fonts (Times New Roman, Arial, Calibri), they'll be embedded in the PDF and appear correctly. If you used a custom font that the converter doesn't have, it will substitute a similar font. For guaranteed font accuracy, use LibreOffice locally which uses the same fonts as your system.
How do I convert ODT to PDF using LibreOffice on the command line?
`libreoffice --headless --convert-to pdf input.odt`. To specify an output folder: `libreoffice --headless --convert-to pdf --outdir /path/to/output/ input.odt`. Batch conversion: `libreoffice --headless --convert-to pdf *.odt`.
Can I make the PDF editable (PDF/A or fillable)?
In LibreOffice: File → Export as PDF → check 'PDF/A-1a' for archival or check 'Create PDF Form' for a fillable PDF. From the command line, LibreOffice exports standard PDF by default; use a PDF editor like pdftk to add form fields afterward.
