ODT is LibreOffice's document format, and plenty of apps still cannot open it. Filemorph converts an ODT file to PDF on your iPhone, so it opens for anyone.

ODT files come out of LibreOffice, OpenOffice and a handful of other open-source suites, and while Word and Pages can sometimes open them, plenty of viewers and upload forms cannot. A PDF removes the guesswork, opening the same way in every browser, phone and desktop.
Filemorph renders the ODT with WebKit, Apple's browser engine, to reproduce text, tables and images from the original document. Complex layouts, macros and embedded fonts may differ from how the document looks in LibreOffice itself, so review anything with heavy custom formatting before treating the PDF as final.
In the app: Convert → To PDF.
PDF opens reliably everywhere, while ODT support varies from one app to the next. Converting an ODT document to PDF is the safer choice any time it is headed to someone whose software you cannot predict.
Yes. Unlike web converters that upload your files to a server, Filemorph converts every file locally using Apple's frameworks. Nothing leaves your device, and it works with no internet connection. This operation is part of Filemorph Pro ($29.99/year, 7-day free trial on monthly and annual plans).
It renders the document's text, tables and images closely, but complex layouts, macros and embedded fonts may differ from how the file looks in LibreOffice. Review heavily formatted documents before sending.
No. Filemorph reads the ODT file directly and does not require LibreOffice or any other office suite.
No. The conversion renders the document as it appears on the page, not comments, revision history or track-changes markup.
