Extract text from 3uTools contact backups (3UC)
To convert 3UC backups to another format, you need 3uTools or other Backup software.
To convert other file formats to the "Contact Backup File" file type, you need software like 3uTools or a similar tool.
A .3UC file is an iOS contact backup created by 3uTools, a Windows-based device management utility for Apple hardware. These files store address book data exported from an iPhone or iPad. Under the hood, a .3UC file is simply a standard ZIP archive containing structured contact data.
The main disadvantage of the .3UC format is its proprietary extension. It is designed specifically for a closed ecosystem. Standard operating systems do not recognize it, meaning you cannot natively open or import a .3UC file into Google Contacts, Apple Contacts, or Android devices without first restoring it through the original software. Furthermore, standard online converters often fail to process this format because they do not expect a standard archive hiding behind a niche backup extension.
To make the data universally usable, you should extract the contents and convert them to standard VCF (vCard) or CSV files. Because our analysis detects the supported underlying ZIP format embedded within the .3UC file, viewing the internal structure or extracting your contacts is still easily possible.
Convert.Guru analyzes your 3UC file, detects the exact format, and lets you read the text inside.
Users also converted CONTACT, VCF, 7, PK and APB files.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our 3UC converter.
