Convert ODT to PDF

No — this conversion pins the layout. An ODT adapts its line breaks to whatever width and font size the reader is using; the PDF fixes page geometry at conversion time, so on a phone you get the whole page scaled down rather than text rewrapped to the screen. That is the right trade when the layout must not move, and the wrong one when the file is for reading on a small device. ODT is the mandated format in several national and EU public administrations and carries no vendor lock-in. PDF is Adobe’s Portable Document Format from 1993, standardised as ISO 32000 and now the universal fixed-layout document.

Not the way you edit the ODT. The PDF is a delivery format: it fixes the layout so it renders identically everywhere, which is exactly why it resists editing. Keep the ODT as the working copy and regenerate the PDF whenever the content changes — round-tripping back out of PDF always loses something.

Body text, headings, lists and simple tables move across cleanly in both directions. The known casualties are the same ones LibreOffice has always had: tracked changes, comments anchored to ranges, footnote numbering schemes and nested table borders. Check those specifically rather than assuming the whole document made it.

Yes, and the ODT would not have. Browsers ship a decoder for PDF and none for ODT, so an ODT link forces a download while a PDF renders inline. That is usually the deciding factor when the file is going onto a web page rather than into an application. A PDF looks byte-for-byte identical on every machine and every printer, which is why contracts, invoices and academic papers all live in it.

Headings, lists, tables and images are kept, and the fonts used are embedded in the PDF, so it looks the same in every viewer. A font that is not installed on our conversion servers (Calibri, for example) is replaced with a similar one, so line breaks can shift. An image file becomes a PDF page that shows the image.

Not on this page: each ODT you upload becomes a separate PDF. To combine them, convert them here first, then join the PDF files into one document with /pdf-merge/.

A document keeps the page size and orientation saved in it, so a Word file set up as US Letter landscape stays that way. A plain text file has no page setup and comes out as A4 portrait. The converter has no page size or orientation setting, so change the page setup in the original file before converting if you need something different.

Yes when the ODT contains real text (DOCX, ODT, HTML, TXT). Image-based ODT produces an image-only PDF — to make it searchable, use /pdf-ocr/ after conversion to run optical character recognition.

Not on this site. The converter has no password or permission settings, and epub.to does not have a PDF password tool. Download the PDF and add a password in a PDF editor that supports it, such as Adobe Acrobat.

It depends mostly on the pictures. A text document usually gives a small PDF, because only the text and the parts of the fonts it uses are stored, while photos and scanned pages make up most of the size of a larger file. The converter has no compression setting; to shrink a finished PDF, run it through /pdf-compress/.
