Convert ATLAS to another file type
To convert ATLAS Texture atlases to another format, you need TexturePacker or other Game software.
Convert a file to ATLAS
To convert other file formats to the "Texture Atlas Coordinate File" file type, you need software like TexturePacker or a similar tool.
About ATLAS files
An .ATLAS file is a plain text or JSON data file used in 2D game development to map coordinates for a texture atlas or sprite sheet. It contains the exact X, Y, width, and height values for individual sprites that have been packed into a single, larger image file, which is usually a PNG. This format is heavily utilized by tools like TexturePacker, the libGDX game framework, and Spine 2D animation software. The biggest frustration with .ATLAS files is that they are not actual image files. If you double-click one, you will just see lines of text or code. Without the accompanying texture image, the .ATLAS file is completely useless. Furthermore, different game engines use entirely different syntax inside their .ATLAS files. A Spine atlas will not natively work in a Unity or Godot project without parsing or conversion. To actually use the graphics, you need to extract them. For editing and web use, unpack the .ATLAS file to individual PNG or WEBP images. If you are migrating game engines, convert the coordinate data to a standard JSON or XML format.
Convert.Guru analyzes your ATLAS file, detects the exact format, and lets you read the text inside.
If you want to convert ATLAS file to JPG, PDF, PNG, GIF, BMP, TIFF, TIF, WEBP, ICO, CUR, PSD or PSB, you can use TexturePacker or similar software from the "Game Sprite Texture Mapping" category. In the File menu, look for Save As… or Export….
To convert RAW, PNG, AI, NEF, PSB, DNG, SVG, GIF, EPS, JPG, ARW or PDF files to ATLAS, try TexturePacker or another comparable tool in the "Game Sprite Texture Mapping" category.
The ATLAS 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 ATLAS converter.
