Extract text from forensic disk images (AD1)
To convert AD1 disk images to another format, you need AccessData FTK Imager or other Disk Image software.
To convert other file formats to the "Forensic Logical Image" file type, you need software like AccessData FTK Imager or a similar tool.
The .AD1 file is a proprietary logical forensic disk image container created by AccessData FTK Imager. Digital forensic investigators use this format to securely store targeted files and folders, preserving their exact directory structure, metadata, and cryptographic hashes (such as MD5 or SHA1) to guarantee evidence integrity in court.
To view or extract data natively, you must use FTK Imager or AccessData's Forensic Toolkit.
The main disadvantage of the .AD1 format is its rigid, proprietary nature. Standard operating systems like Windows, macOS, or Linux cannot mount .AD1 files out of the box. You are forced to install specialized forensic tools just to view a single document inside the container. Additionally, sharing an .AD1 file with someone who does not have a digital forensics background guarantees they will not be able to open it.
For general data extraction, you should convert the .AD1 contents to a standard ZIP archive so anyone can open it. For cross-platform forensic analysis using open-source tools like Autopsy, convert the image to RAW or DD. Drop your file here to view and convert it securely right in your browser - free, online, and without installing heavy forensic software.
Convert.Guru analyzes your AD1 file, detects the exact format, and lets you read the text inside.

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 AD1 converter.
