About IBK files

The .IBK extension typically identifies a backup archive created by the now-defunct IncrediMail email client or an e-book file used by ICE Book Reader.

For IncrediMail users, this format presents a significant hurdle: the service shut down in 2020, making the proprietary restoration tools obsolete. These files are often just renamed ZIP archives containing your email history, contacts, and attachments, but they are inaccessible to modern clients like Microsoft Outlook or Mozilla Thunderbird without modification. Users frequently encounter these legacy files when migrating data from old hard drives and discover they cannot simply "open" them to view old correspondence.

For ICE Book Reader users, the .IBK format is a highly compressed digital book container. While efficient for storage, it lacks the broad compatibility of EPUB or PDF. You cannot open an IBK e-book on a Kindle, iPad, or standard web browser, locking your library to a specific Windows application.

Best Conversion Targets:

For Email Recovery: Rename to ZIP to extract contents, or convert individual message files to EML or PDF for long-term archiving.
For E-Books: Convert to EPUB for e-readers or PDF for universal viewing across mobile and desktop devices.
For Databases: If your file is an InterBase or Firebird backup, it must be restored using the respective database management tools rather than converted.

Convert.Guru analyzes your IBK file, detects the exact format, and lets you read the text inside.
