Now when you open , save , import or export anything in Photoshop one thing always matter that is their Format.

Formats means type of file, sometime some formats open in only specific software only. Like .psd file only opens in Photoshop for re edit. But sometime these formats can be import in other software, like .ai files of adobe illustrator can be import in photoshop.
Every format has an extension. like Photoshop has its extension .psd.
Every extension starts with DOT “.” just like .psd, .ai, .max etc as they are written with file name like an image named as flower of JPEG format so its name will be flower.jpg

Regular formats used in Photoshop are:-

  • PSD is format of Photoshop file in which you will save all your working so that you can re-edit it anytime .These files are also called as master files. Only disadvantage of these files are that they are really big in size.
  • JPEG is widely used image format.  You can see it becomes default format in digital media. It is most favorable format for sharing pics on web. Whether it is photo sharing websites or facebook. Advantage of this format is that it is compressed so low on size but on other hand downfall is also same that as it is compressed you have to compromise with the quality.
  • PNG  is another important format in today’s media world. As it has transparent background it is very effective format in editing. As it has transparent background you can save your clip arts in it or you need png pics to merge multi pics easily. We will use it many time in coming tutorials.
    Biggest advantage over JPEG is that it compress image with lossless file format so that you can save it multiple times without losing quality.
    Its Disadvantage in web media is that it is not supported by old browsers, but you can ignore this as if you are making media for today’s and future technology.
  • GIF is older format than jpeg also. It is first choice for web graphics but not for web photos as it can only display 256 colors.
    For Web Designing it is for sure that GIF is #1 as  it is suited for banner and buttons , it is small in file size and supported by all popular browsers.
    It supports transparency but not like PNG it supports one level transparency means either it is fully transparent or fully opaque so because of this image get harsh impression.
  • PDF – To share files and document it is very popular format. It is like electronic document folder.
