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

  1. 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.

  1. Install an OpenDocument-compatible suite that supports .OTI (commonly LibreOffice or Apache OpenOffice).
  2. 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.
  3. 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.

  1. Use the application’s “New from Template” or equivalent function to create a new file based on the .OTI.
  2. 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.

  1. Re-download or re-copy the file and try again.
  2. Confirm the sender/source and ask for the file to be re-exported as an OpenDocument image template (.OTI).
  3. Try opening it in a different OpenDocument-compatible suite to rule out an application-specific parsing issue.

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.
