Convert ODT to PDF
Up to 3 files at once, 100 with Pro. Mixed formats are fine.
ODT is LibreOffice's own format and LibreOffice is what converts it here, which makes ODT to PDF the most faithful document conversion on the site — the same software reading a file it defined, with nothing interpreted or guessed. Drop the file above; it is converted on our server and deleted the moment the job finishes.
Why ODT converts more faithfully than DOCX
Every document conversion involves one program reading a file another program wrote, and most of the difficulty lives in that gap. This one does not have the gap. ODT is the OpenDocument format, LibreOffice is what produced it, and LibreOffice is what converts it — the same software reading a file it defined.
A DOCX arriving at LibreOffice has to be interpreted: styles resolved, layout rules mapped from one model onto another, Microsoft fonts substituted with metric-compatible stand-ins. It works well, but there are decisions being made. With ODT there are no decisions. The file already describes itself in the terms the converter uses.
The one place a difference can still creep in
Fonts. Our server carries the common open families — Liberation, DejaVu, Noto — plus metric-compatible versions of the usual Microsoft ones. A document set in any of those converts exactly.
A document using a font that exists only on your own machine will be substituted, and because the substitute has different letter widths, lines can break in different places. If your document uses something unusual, exporting from your own LibreOffice is the safer path.
When to use this instead of LibreOffice itself
If you have LibreOffice open, use File → Export as PDF. It is the same engine, it happens instantly, and nothing leaves your computer.
This page exists for when LibreOffice is not in front of you — a borrowed laptop, a phone, a locked-down work machine, or a file somebody sent you in a format you have no software for. That is a real situation and it is the one this is for.
What comes through the conversion
Headers, footers, page numbering, tables, embedded images, hyperlinks, and a table of contents generated by LibreOffice keeps its internal links. Tracked changes render as the document displays them, so accept or reject them first if you want a clean copy.
Where your file goes
This is one of the conversions that runs on our server rather than in your browser, because reading an office document properly means running an office suite. The file is uploaded over an encrypted connection, converted, and deleted the moment the job finishes. No copy is kept and nobody looks at it.
Most of this site never touches your files at all, and where that is not true we would rather point at it than let you assume.
How to convert an OpenDocument file to PDF
- Drop your ODT onto this page, or click to choose it.
- It is converted with LibreOffice — the same program that wrote the format.
- Download the PDF. Your original is deleted as soon as the job finishes.
ODT vs PDF: the same engine on both sides
| ODT | ||
|---|---|---|
| Full name | OpenDocument Text | Portable Document Format |
| File extension | .odt | |
| Media type | application/vnd.oasis.opendocument.text | application/pdf |
| Compression | — | Either, depending on the setting |
- Quality
- The result is a close reconstruction rather than an exact copy. Check it before relying on it.
- Where it runs
- This conversion runs on our server, because it needs software a browser cannot run.
- What can be lost
- Layout is reproduced with metric-compatible substitute fonts. Macros, comments and tracked changes are not carried over.
ODT to PDF: fidelity, fonts and your file
- Are my ODT files uploaded anywhere?
- Yes — this conversion needs software that cannot run in a browser, so the file is uploaded over an encrypted connection. It is deleted as soon as the job finishes, and the result is removed after 60 minutes.
- Will the PDF look exactly like my document?
- Yes, closer than for any other document format here. ODT is LibreOffice's own format and LibreOffice is what does the conversion, so it is the same program reading a file it wrote. There is no interpretation between them.
- Why not just use File → Export as PDF?
- You should, if LibreOffice is in front of you — it is the same engine and it is faster than an upload. This page is for when it is not: a borrowed computer, a phone, a machine where you cannot install anything.
- Do my fonts come through?
- Fonts installed on our server are used directly, and the common open families are all there. A document using a font that only exists on your own machine will be substituted, which can move line breaks. If the document uses something unusual, exporting from your own LibreOffice is the safer route.
- Are tables, headers and images preserved?
- Yes. Headers, footers, page numbering, tables, embedded images and a generated table of contents all survive, with internal links intact.
- What happens to my file?
- It is uploaded over an encrypted connection, converted, and deleted as soon as the job finishes. Nobody reads it. Most conversions on this site never leave your device; document conversions are the exception and we would rather say so.
