About UBK files
The .UBK file extension is primarily used as a backup file format, but it is heavily fragmented across completely unrelated software ecosystems. The three most common sources are Samsung S Note, Ubiquiti UniFi network controllers, and Uni Micro accounting software. This fragmentation causes immense confusion for users who find a .UBK file on their system and cannot open it natively. The main disadvantage of .UBK files is their proprietary nature, which artificially locks user data inside specific applications. For example, Ubiquiti uses .UBK to store router and network configuration settings. If the controller hardware fails, reading the raw data inside the .UBK file is exceptionally difficult without restoring it to an identical UniFi device. Similarly, Uni Micro uses this format to archive accounting databases, making the data completely inaccessible without an active software license. However, many .UBK files are simply standard file formats in disguise. Samsung S Note .UBK image backups are actually standard PNG files, while Uni Micro accounting backups are often standard ZIP archives. Because standard online converters rely entirely on the file extension rather than the internal file signature (magic bytes), they fail to process .UBK files and return an unsupported format error. To reclaim your data, the best target formats are PNG (for Samsung images) and ZIP (for Uni Micro archives). Just drag and drop your file into convert.guru to identify the format, view it, and convert it when possible. Our analyzer ignores the deceptive .UBK extension, inspects the underlying binary header, and extracts the embedded standard formats so you do not lose access to your own information.
Convert.Guru analyzes your UBK file, detects the exact format, and lets you read the text inside.
Users also converted UBKY, TK3, TR3 and XEB files.

The UBK Converter Story
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 UBK converter.
