GIF (Graphics Interchange Format) is a
useful 8-bit-per-pixel bitmap image format created by
CompuServe in 1987. Since then it has become wide used for
its wide support and portability. GIF supports online
drawings, pictures with blocks of solid colors, and pictures
with sharp boundaries between colors. GIF is unsuitable for
photographs due to its 256 distinct colors from the over 16
million representable in 24-bit RGB limitation. However,
there is a hack that can overcome this limitation under
certain circumstances. On the process of compressing, there
is no information lost in GIF files.
ICO is a image file extension for
small Windows icon. *.ICO can store more than one images
with different sizes or colors. Normally it is 16*16 and
32*32 pixels square with 16 colors. Windows XP or VISTA
supports bigger size like 48*48 or 256*256 and 32-bit color
depth.
BMP (Bitmap) is very popular nowadays due
to the common use of Windows. That is because BMP is the
standard format used by Windows for saving image files. It
contains more image information than the JPEG, and there is
almost no compression of images. So it takes a larger disk
space. Presently, 24 bits per pixel BMP files are the most
common in all the 1, 4, 8, 15, 24, 32, 64 bits per pixel BMP
files.To convert gif ico to

PSD/PDD is the special format for Photoshop (an image
designing software) developed by Adobe Cop. PSD files could
be saved in RGB or CMYK mode, which couldn’t only customize
and save the color, but also save information on layer,
channel and path of Photoshop. It’s the only format that
could support all color modes for images. As big as its size
is, it could be applied in most plane software and some
editing software. |
