Use the lowest bit depth that can handle all colours in your image, although some image editing programs cannot create 2-bit colour images. If you are converting an image with many colours (perhaps because somebody saved the original as a JPEG, avoid this) to a PNG, you may want to reduce the number of colours at the same time; see Wikipedia ...
The GDF format is often used in brain–computer interface research. [4] [5] [6] However, since GDF provides a superset of features from many different file formats, it could be also used for many other domains. The free and open source software BioSig library provides implementations for reading and writing of GDF in GNU Octave/MATLAB and C ...
JPEG compresses images down to much smaller file sizes, and has become the most widely used image file format on the Internet. [28] Its highly efficient DCT compression algorithm was largely responsible for the wide proliferation of digital images and digital photos, [29] with several billion JPEG images produced every day as of 2015.

TIFF/EP, TIF, TIFF – Tag Image File Format / Electronic Photography, ISO 12234-2; tends to be used as a basis for other formats rather than in its own right. VTF – Valve Texture Format; WEBP – WebP, an image format designed for the web that can provide both lossless and lossy compression. XBM – X Window System Bitmap
The Neuroimaging Informatics Technology Initiative (NIfTI) is an open file format [1] commonly used to store brain imaging data obtained using Magnetic Resonance Imaging methods. References [ edit ]
The raw IMG file format is used by several tools: RaWrite and WinImage use the IMG disk image format to read and write floppy disk images. ImDisk and Virtual Floppy Drive can mount a raw image of a floppy disk to emulate a floppy drive under Microsoft Windows. Nero Burning ROM supports reading IMG files for creating bootable CDs.
Intel hexadecimal object file format, Intel hex format or Intellec Hex is a file format that conveys binary information in ASCII text form, [10] making it possible to store on non-binary media such as paper tape, punch cards, etc., to display on text terminals or be printed on line-oriented printers. [11]
CIF (Common Intermediate Format or Common Interchange Format), also known as FCIF (Full Common Intermediate Format), is a standardized format for the picture resolution, frame rate, color space, and color subsampling of digital video sequences used in video teleconferencing systems. It was first defined in the H.261 standard in 1988.
