How to open .OTI files on iOS
To open .OTI files on iOS, iOS may not natively preview .OTI; if it won’t open in Files/Quick Look, transfer the file to a desktop OpenDocument suite (e.g., LibreOffice/OpenOffice) to open it as a template.
Step-by-step instructions
- iOS may not natively preview .OTI; if it won’t open in Files/Quick Look, transfer the file to a desktop OpenDocument suite (e.g., LibreOffice/OpenOffice) to open it as a template.
Common issues
The .OTI file opens in the wrong app (or shows as an unknown file)
The system may not have an OpenDocument-capable suite installed or may not have the correct MIME mapping/app association for .oti.
- Install an OpenDocument-compatible suite that supports .OTI (commonly LibreOffice or Apache OpenOffice).
- Set the default app for .OTI (or for the MIME type application/vnd.oasis.opendocument.image-template) to your office suite via your OS file association settings.
- On Linux, ensure your desktop MIME database (shared-mime-info) is up to date so .oti maps correctly.
It opens, but I can’t edit or it keeps overwriting the template
Templates are meant to be used as a starting point; some apps open templates in a mode intended for creating a new document rather than editing the template itself.
- Use the application’s “New from Template” or equivalent function to create a new file based on the .OTI.
- If you need to modify the template, save a copy first so the original template remains unchanged.
The file won’t open or reports it is damaged
The OpenDocument package may be incomplete (bad download/transfer) or not actually an .OTI file despite the extension.
- Re-download or re-copy the file and try again.
- Confirm the sender/source and ask for the file to be re-exported as an OpenDocument image template (.OTI).
- Try opening it in a different OpenDocument-compatible suite to rule out an application-specific parsing issue.
Still can’t open your .OTI file?
Recover a deleted or lost .OTI file
If the file was deleted by mistake or the drive was formatted, data recovery software may be able to get it back. Stop writing to that drive right away, because new data can overwrite what you want to recover.

Security note
.OTI is an OpenDocument package type; treat it like any complex document format and only open templates from sources you trust, because malformed documents can trigger vulnerabilities in document parsers.
