CompressIt can help you to select the
most effective compression format for storing your image files!

This utility will
allow you to free a disk space of your computer by reducing a file
size of stored images even if the images have been already
compressed.
CompressIt has an
intuitive easy-to-use interface. All you need to do is just open an
image you want to be compressed, compare file sizes of created JPG,
GIF, PNG, TIF images and then save the most optimal result.
|
It is also a good
tool for preparing images for the Web. You will be able to
create: |
|
|
progressive JPG files and
interlaced GIF files, in which
a
low-resolution version of the image appears in a
browser
while the full image is downloading |
|
|
transparent GIF files, in
which you blend the edges of
the image
with a Web page background color |
|
|
lossless true color PNG
files, which can be used when
you need
to show an image on a Web page without
any
quality losses |
|
To get more compression you can change initial
JPG, GIF, PNG or TIF settings.
JPG settings:
JPG is a
lossy compression format, it means that a compressed image will lose
its quality anyway, yet you can significantly reduce file size with
relatively low quality loss. You can change JPG quality and
Smooth factor to get best quality and smallest file size of
compressed image. JPG quality
can vary from 1% (lowest quality and smallest file size) 100%
(highest quality and largest file size).
Smooth factor can vary from 0 (no
smoothing) to 100 (max smoothing). If
Smooth factor is not zero then an
image will be smoothed before compression. Smoothing improves
compression ratio.
GIF settings:
GIF is a
lossy compression format, an image you want to be compressed will be
converted to 2, 4, 8, 16, 32, 64, 128 or 256 colors. The less number
of colors you choose, the more compression you can get. Use
differing option can improve quality of compressed image but it
will increase the file size.
PNG settings:
There are
two types of PNG files: lossy and lossless. You can choose
Lossless compression
option if you need compress an image without any
quality losses. However, lossless PNG files are often much larger
than JPG or GIF files of the same image. So if you do not need a
lossless compression you can uncheck
Lossless compression box and specify
number of colors similar to GIF compression.
TIF settings:
TIF is a
good lossless compression format especially for black&white images
(scanned faxes, scripts, books). You can also create color TIF
files, note that such files will be much larger than PNG files.
Choose Convert to black&white option if you want compress an
image using very effective for black&white images compression
methods: CCITT Group 3, 1D; CCITT Group
3, 2D; CCITT Group 4, 2D. You can also
specify a dpi resolution for TIF file, it will not affect the file
size.
