About ASICS files
An .ASICS file is an Associated Signature Container (Simple) defined by the ETSI standard, widely used in Europe (under eIDAS regulations) to bundle a document with its digital signature. Technically, it is a standard ZIP archive containing the original file (often PDF or DOCX) and a signature file (usually XML or P7S conforming to XAdES).
The primary challenge users face is that standard operating systems do not recognize the .ASICS extension, leaving the file "unopenable" without specialized government software like DigiDoc. Furthermore, while the container verifies authenticity, most users simply want to read the enclosed document. Because it is a proprietary-labeled ZIP file, it can be difficult to view on mobile devices or web browsers without conversion.
Best Conversion Targets:
To Extract Content: Convert (or rename) to ZIP. This allows you to unzip the container and access the inner PDF or DOCX file immediately.
For Viewing: Extract the inner document to PDF for universal compatibility on all devices.
For Archiving: Keep the original .ASICS file if legal verification of the signature is required; otherwise, archive the extracted payload.

The ASICS 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 ASICS converter.
