JPG (Joint Photographic Experts Group)
A JPG file is a very common file format for digital photos and other graphics. When these types of files are saved they use a format known as 'lossy compression' or 'lossless compression' this means that the quality of the image is lost when the file starts to decrease. This format is the most common file for taking images with a digital camera, and is also used for photos and other graphics on websites.
TFF (Tagged image file format)
TFF format is the most common file for images, especially the ones used for graphic design for example photo shop. This type of file can be saved without compression, for example it doesn't allow the file to get smaller therefore the file will be very large, on the other hand this type of file can also be compressed to a lower file size to allow more memory space for other things but cannot be compressed as much as a JPG. This type of file is commonly used in print design and desktop publishing because they allow storage of large high quality images such as photos.
PNG (pronounced ping for portable network graphics)
PNG is a file format used for image compression that is widely used on todays modern internet. The PNG used losless compression just like JPG, this means it doesn't have any blurriness or loss of quality, which means all the image information is restored when the file is decompressed during viewing. This type of format can be put onto any transparent background rather than specific colours.
BMP (bitmap)
This file type doesn't need to contain colour-coded information for each picture element, it is known as a matrix of dots or as a raster format. A BMP has limited use because of its simple nature, it doesn't have any colour depth therefore the image will be blurry when zoomed in.
PSD (photoshop document)
This type of file format is used in adobe photoshop for saving data. This file format allows the user to work with the images individual layers even when the file has already been saved. Once the image is finished the layers are flattened by conversion so it can be shared, once finished the file cannot be converted back so the user cannot work with the individual layers anymore.
AI (adobe illustrator)
Adobe illustrator is a programme used by artist and graphic designers to create vector images. Once these images are finished they are used for things like company logos and even personal work both in print and digital form. The programme is very hard to use and to understand but once you get your final piece it is well worth the learning curve.
WMF (windows metafile)
A metafile is a file that contains information regarding one or more files, it is commonly a graphic file format and containing vector graphics or bitmap files. A WMF file can contain both image and text it is usually found in Microsoft packages such as word, powerpoint and publisher but is not usually used in the world of professional design.
