This format is also able to save images in several modes provided by Photoshop color. You can save this file format if you want to edit it back.
BMP (Bitmap Image)
This file format represents a flexible graphics format for the Windows platform so it can be read by any graphics program. This format is capable of storing information in a quality level of a bit till 24 bits. The weakness of this file format is not able to save the alpha channel, and there are obstacles in the exchange platform. To create an object as a desktop wallpaper, save your document with this file format. You can compress this file format with RLE compression.
This file format is capable of storing images in color modes RGB, Grayscale, Indexed Color, and Bitmap.
EPS (Encapsuled Postcript)
This file format is frequently used format for document exchange between graphics program. In addition, this file format is often used when wanting to print pictures. The advantage of this file format using postscript language so that this file format recognized by almost all print preparation programs.
The weakness of this file format is not able to save the alpha channel, so that many users of Adobe Photoshop using this file format when the images are done already final.Ã⠀ SA, this file format capable of storing images with color modes RGB, CMYK, Lab, Duotone, Grayscale, Indexed Color and Bitmap. Besides the file format is also capable of storing clipping path.
JPG / JPEG (Joint Photographic Expert Group)
This file format can compress the object with a level of quality in accordance with the options provided. The file format is often used for storing images to be used for web pages, multimedia, and other electronic publications. This file format is capable of storing images with color modes RGB, CMYK, and Grayscale. This file format is also able to save the alpha channel, but because of its orientation to the electronic publication of this format is relatively smaller size compared to other file formats.
GIF (Graphic Interchange Format)
This file format can only store in 8 bit (color mode only supports Grayscale, Bitmap and Indexed Color). This file format is a standard format for electronic publications and the Internet. File format capable of storing two-dimensional animation that will be published on the internet, web page design and electronic publications. This file format can compress with a smaller size using LZW compression.
TIF (Tagged Image File Format)
This file format is capable of storing images with quality up to 32 bits. This file format can also be used for the exchange of cross-platform (PC, Machintosh, and Silicon Graphics). This file format is one of the selected format and is preferred by computer users, especially graphics-oriented publications (print). Almost all programs that can read bitmap file format is also able to read the TIF file formats.
PCX
This file format was developed by a company called Zoft Cooperation. This file format is a format that is flexible, because almost all programs in the PC able to read the image with this file format. This file format capable of storing information for one bit depth to 24 bit but was unable to save the alpha channel. This file format is capable of storing the image with color mode RGB, Grayscale, and Indexed Color Bitmpa.
PDF (Portable Document Format)
This file format used by Adobe Acrobat, and can be used by the pixel and vector-based graphics. This file format is capable of storing images with color modes RGB, CMYK, Indexed Color, Lab Color, Grayscale and Bitmap. This file format is not able to save the alpha channel. This file format is often used JPG and ZIP compression, except for Bitmap color mode that is using CCIT.
PNG (Portable Network Graphic)
This file format serves as an alternative to the GIF file format. This file format used to display objects in web pages. The advantages of this format compared to the GIF file is its ability to save files in the bit depth to 24 bit and capable to generate the background (background) transparent with smooth edges. This file format is able to store an alpha channel.
PIC (Pict)
This file format is standard in the Macintosh graphics applications and text-processing program with a quality medium for the transfer of documents between applications. This file format is capable of storing images with the RGB color mode with an alpha channel as well as Indexed Color, Grayscale and Bitmap without alpha channel. This file format also provides a choice between 16 bit and 32 bit in RGB color mode.
TGA (Targa)
This file format is designed for platforms that use the True Vision Targa Video Board. This file format is capable of storing images in RGB color mode with 32 bits and an alpha channel, as well as Grayscale, Indexed Color, RGB and in 16 or 24 bits without alpha channel. This file format is useful untukÃ⠀ SA, save the document from the rendering of an animation program with the output of sequences such as 3D Studio Max.
IFF (Interchange File Format)
This file format is commonly used to working with the Video Toaster and the process of exchanging documents from and to Comodore Amiga System. This file format recognized almost all the programs contained in PC graphics and be able to save a bitmap image with color mode. This file format is not able to save the alpha channel.

RAW
This file format is a flexible file format for exchanging documents between applications and platforms. This file format is capable of storing color modes RGB, CMYK, and Grayscale with an alpha channel and color mode Multichannel, Lab Color and Duotone without alpha channel.
DCS (Desktop Color Separation)
This file format was developed by Quark and is a standard format for. Eps. This format is able to store pictures with Multichannel and CMYK color mode with an alpha channel and a lot of spot channels. This file format is capable of storing clipping path and is often used for process printing (publishing). When saving files in this format will be saved is the fourth channel of the image and a preview channel.
COMPRESSION FORMAT
Some programs are oriented primarily on electronic publications and multimedia file format always requires a small size so that when opened will not be slow. For this purpose the necessary compression.
Here is the file format of electronic publications and multimedia-oriented with each compression.
RLE (Run Length Encoding)
This compression can compress files without losing detail. Used by Adobe Photoshop, TIFF and most of the programs included in Windows.
LZW (Lemple-Zif-Welf)
Just like RLE compression, compression is also able to compress files without losing detail. Compression is used by the TIFF, PDF, GIF and postscript format that supports the language. Compression is very good for compressing images with large areas using a color.
JPG (Joint Photographic Experts Group)
This format compresses the file by eliminating detail. This file format is often used by JPG, PDF, and postscript formats using the language. Compression is very good for images with continuous tones like photos.
CCIT

NOTES
- When storing documents in file formats that can not save the information layer, then you must convert the image into the image flaten first.
- The file format that can store only Duotone color mode EPS, RAW, and PSD. Therefore, when want to save in another format, you must first change the color mode, the RGB when the document does not want printed, because his Duotone information will be resolved into RGB.
- The file format can store yan Color Lab color mode is PSD, RAW, TIF, PDF, and EPS. File format that can store only CMYK color mode PSD, RAW, EPS, TIF, JPG, PDF, dams SCT.
Indexed Color Mode Color # can save a file format based on its color-indexed setting. - RGB color mode can saved on all existing file formats in Adobe Photoshop.
- The format recommended by the professional designer is :
- PSD = for documents still want to be edited again
- EPS = for the document is final preparation for printing
- JPG = to print with the above 8-bit compression and for image compression in the web under
- GIF = for illustration and animation on web pages
- IF = to print, cross-platform document exchange as well as animated sequences
This time is still active in the work
