Convert a file to ATR

To convert other file formats to the "Emulator Disk Image" file type, you need software like Atari800 or a similar tool.

About ATR files

The .ATR extension is a multi-purpose filename used by three distinct technical communities, often leading to confusion. Primarily, it functions as a Disk Image for Atari 8-bit computers (400/800/XL/XE series), encapsulating the raw data of a legacy floppy disk (typically 90KB to 128KB) into a single file. These files are essential for retro-gaming but suffer from significant interoperability issues: they cannot be mounted by modern operating systems like Windows 11 or macOS without specialized emulator software like Altirra or Atari800.

Secondarily, .ATR files are used by ANSYS for engineering simulation results and by PhysioNet tools (like WFDB) for annotating physiological signals (ECG/EEG). The friction here is proprietary lock-in; ANSYS files require expensive enterprise licenses to open, and PhysioNet annotations are binary files unreadable in standard text editors.

Conversion Recommendations:

For Atari Emulation: If you need to access specific files inside the disk image, convert or extract the contents to XEX (executable) or raw binary. If archiving, keep as .ATR.
For Data Analysis (ANSYS/PhysioNet): To make the data usable in reports or spreadsheets, the ideal workflow is converting the internal data tables to CSV, XLSX, or TXT. This allows for immediate analysis in Microsoft Excel or MATLAB without needing the original host software.

Convert.Guru analyzes your ATR file, detects the exact format, and lets you read the text inside.

Users also converted ART, ZIP, DAT, DSK, DMG, AD1 and PDF files.

The ATR 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 ATR converter.
