Image File Formats 4/17

Bitmap 

(jpg, png, gif, bmp, psd, tiff, heic, psb, camera raw): 

jpg : (joint photographic expert graphics) a digital image format which contains compressed image data, typically the file format for sharing photos/images on the internet between mobile platforms and pc. 

png : (portable network graphics) is a compressed, raster (bit-mapped) image, a file format used for lossless image compression. This file tends to have a larger file size and can handle a high amount of colors while keeping the load time fast enough to use online.

gif : (graphic interchange format) a raster file format designed for relatively basic images that appear mainly on the internet. can support up to 8 bits per pixel and can contain 256 indexed colors. allow images or frames to be combined, creating basic animations.

bmp : (bitmap) a simple raster graphics image file format designed to store bitmap digital images independently of a display device and it can handle multiple color depths, profiles, and alpha channels. It also can be data compressed. 

psd : (photoshop document) an image file format native to Adobe's Photoshop Application. These files are commonly used for containing high quality graphics data. File supports multiple image layers and various imaging options.

tiff : (tag image file format) is a file format for storing and interchanging raster images. TIFF files can have a bit depth of either 16-bits per channel or 8-bits per channel, and multiple layered images can be stored in a single TIFF file.

heic : (high-efficiency image format) an updated variant of the High Efficiency Image Format (HEIF), traditionally used by Apple across its mobile devices. A typical HEIC file is about half the size of a JPEG file of the same image quality. 

psb : (photoshop big) similar to a PSD, a raster file format, it allows for a considerably bigger file size. The Adobe Large Document Format supports documents up to 300,000 pixels in any dimension and file sizes can range up to 4 exabytes. 

camera raw : contains raw or minimally processed data from a digital camera's image sensor, a motion picture film scanner, or another image scanner.

Vector

(ai, pdf, svg, indd, eps, ait):

ai : (adobe illustrator) the native vector file type for Adobe Illustrator. You can't usually open an AI file without design software. 

pdf :(portable document format) a file format that has captured all the elements of a printed document as an electronic image that users can view, navigate, print or forward to someone else. 

svg : (scaleable vector graphic) is a platform for two-dimensional graphics. Key features include shapes, text and embedded raster graphics, with many different painting styles. These files are extremely flexible, easy to update, and don't lose quality when resized.

indd : (indesign document)  is the default file type for InDesign. These are both vector & bitmap file compatible. This is used to create books, magazines, brochures, flyers and other print or web items with a strong design element 

eps : (encapsulated postscript) is ideal for scaling images. image data it retains ensures the resolution remains high, even when stretched to larger proportions. This file also benefits from a lossless form of compression.

ait : (adobe illustrator template) is an Illustrator template file that's used to create multiple Adobe Illustrator (. AI) files. This file can contain artwork like a logo, textframes, not only an artboard.

Layout 

(imdd, idml): 

indd: (indesign document)  is the default file type for InDesign. These are both vector & bitmap file compatible. This is used to create books, magazines, brochures, flyers and other print or web items with a strong design element 

idml: (indesign markup language) is an exchange format in order to open InDesign documents in older InDesign versions or in other DTP(desktop publishing) programs. This file also uses a ZIP container. This file also contains meta data, formatting attributes, layout properties and multimedia content objects.
