About OZIP files
The .ozip file format is a proprietary, encrypted Over-The-Air (OTA) firmware update package used by OPPO and Realme Android smartphones. These files are designed to be processed internally by the stock recovery environment on the mobile device. Users often need to convert or extract these files when they want to install the firmware using custom recovery tools like TWRP, or when they need to extract individual system partitions such as .IMG files for rooting and modding. The main disadvantage of the .ozip format is its proprietary encryption. Standard archive managers like 7-Zip or WinRAR cannot read or extract the internal contents. They are locked behind device-specific cryptographic keys, making standard conversion virtually impossible without specialized community decryption scripts like ozip2zip. Because this is a closed, proprietary format, standard online converters fail to process it. Drag and drop your file to see what it is and convert it if supported. convert.guru can identify the file format, inspect the headers, and show internal metadata. If our analysis detects an unencrypted variant or a supported underlying format, viewing or conversion to standard .ZIP or .IMG may still be possible.
Convert.Guru analyzes your OZIP file, detects the exact format, and lets you read the text inside.
If you want to convert OZIP file to ZIP, SYS, DLL, EXE, DRV, VXD, 386, COM, BAT, CMD, SCR or PIF, you can use OPPO Stock Recovery or similar software from the "Android Firmware Update" category. In the File menu, look for Save As… or Export….
To convert MSI, EXE, REG, MST, LNK, CAB, CAT, DRV, INF, SYS, MSU or DLL files to OZIP, try OPPO Stock Recovery or another comparable tool in the "Android Firmware Update" category.
The OZIP 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 OZIP converter.
