What is an ATF File?

How to Open, Edit, & Convert ATF Files

ATF Files.

A file with the ATF file extension is most likely an Adobe Photoshop Transfer Function file. These types of files store settings that allow pictures transferred to film to be printed in the proper color.

Unrelated to Photoshop, some ATF files you find may be Adobe Texture Format files, a container format used to store image data for Adobe Flash/Air games created using Stage3D. Since it's a container format, a single ATF file can deliver textures to multiple platforms, like iOS, Android, and Windows.

ByteArray.org has a good explanation of this format.

The ATF extension is also used by GenePix analysis software as Axon Text files, a plain text format.

Alternativa Texture files use the ATF extension too, as a format to store 3D model textures.

How To Open an ATF File

ATF files that are Adobe Photoshop Transfer Function files can be opened with Adobe Photoshop.

You should be able to open ATF files that are Adobe Texture Format files in any game engine that supports Stage3D, like Starling. Otherwise, you can just use a converter program to save the ATF file to a more common format supported by any image viewer (see how to do this below). Another option for opening this format is to use ATFViewer (part of ATF Tools).

Axon Text files are plain text files similar to a database or spreadsheet file. This means that Microsoft Excel, as well as most free spreadsheet software programs, are probably the best bet for these.

Since they're text files, any text editor will do the job too, like Notepad++. ATF files of this format are also used by the Molecular Devices GenePix software.

Note: Even though Axon Text files can most likely be viewed correctly using a spreadsheet program like Excel, it's important to understand that Excel (and probably most other spreadsheet tools) doesn't recognize files ending in .ATX.

This means instead of double-clicking the file to open it, you have to open the program first and then use the Open menu to find the ATX file.

The only way I know to open ATX files that are Alternativa Texture files is with the AlternativaPlayer 3D model viewer, but that website doesn't seem to work anymore. Chances are, though, that your ATF file belongs to one of the other formats I already mentioned.

Considering the number of different formats that use the ATF extension, you may find that the program that opens the one you need access to isn't the one that supports the format. If you think that might be the case, and you know the program that should open it, see my How To Change File Associations in Windows tutorial for help.

Note: If your file isn't opening with the programs I've already mentioned, double-check to make sure you're reading the file extension correctly. Some files, like AFT (Ancestry.com Family Tree Database) files, share the same letters as ATF files but really have nothing at all to do with the format.

How To Convert an ATF File

Adobe Texture Format files can be converted to PNG images using the free ATF2PNG tool. Once the ATF file is in the PNG format, you can use just about any free image converter to save the PNG to JPG, GIF, BMP, and other image formats.

Also, see this tutorial at Starling Wiki for help converting an ATF file using Adobe AIR and command-line commands.

Any text editor can convert an Axon Text file to another text-based format. You might also be able to use the GenePix software to save the ATF file to some other format.

I don't see any reason for converting Adobe Photoshop Transfer Function files. Also, given that I don't know of any way to open Alternativa Texture files, I also know of no converter that can be used in that format.
