Image Resizing and File Compression
For Edline pictures need
to be no more than 314 pixels wide (the height does not matter), smaller
than 75 Kilobytes (larger pictures are difficult to display for families
using dial-up modems), and type .jpg, or .gif
And file compression
allows for faster viewing as the file Kilobyte size gets lower.
Below are my reviews and results using
free and online programs I found on Google.
Free
Resizing Software
IrfanView Free, easy to use and many
graphic features. I really like using
this for photo adjustments. Works with
many formats and can save as icon files. However while it does good for quality for resizing the compression
results are not as good as others since quality is prime concern. Even tested
the several Resample options but no difference in results.

PIXresizer – FREE http://bluefive.pair.com/pixresizer.htm
This is one recommended by
the district.
It is easy to use with
many options. In fact it is probably the easiest to use.
Nice that allows for
different format savings, rotation, grayscale, and Save As
However, the compression
is not as good until to get to much smaller sizes. This is due to the default
compressions being high quality. The
trick to changing is to click on the “boxed” full format name to reveal the
compression settings, but seemed to only work with jpeg. The Default is 90. I tried at 50 for the 640 size and it
dropped from 107 K to 45 K without noticeable drop in quality. So if you are willing to take the time to
make these settings then PIXresizer is the
compression winner.
Microsoft PowerToys for Windows XP
http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx includes
Image Resizer
This PowerToy enables you to resize one or many image files with a
right-click on the file icon. So very
easy to use. Compression was acceptable for larger images but as you got to
smaller sizes, they were disappointing.
Recommended for ease of
use.
Visualizer Photo Resize http://www.freeimagebrowser.com/resize/ or http://www.snapfiles.com/get/vphotoresize.html
At first I was put off by the interface as not
Windows standard and not clear on how to use.
It seemed to me only good for batch jobs
But after playing around I found that if use
preview button on front page the program
becomes easy to use even though it does do follow standard Windows menus
I liked that the
aspect ratio was automatic and you could select others than 4 x3. Another feature I liked was it showed the
document size in inches or cm after setting your pixels. Another good feature was you had four
Compression Quality choices. For the
chart I used Max quality but high might be acceptable if even lower compression
needed. Even at Max quality was one of
the best in lowering the KB. Also does
watermarks (even images), grayscale, color auto adjust, and creates albums
with choices of skins. It takes a little to learn but recommend as great
compression and many good features.
Fotosizer http://www.snapfiles.com/get/fotosizer.html
Of the programs does best compression result but
not easy to use for the general user being not so user friendly.
To open a file need to “Add Image”
There is no Save As, uses Start so be sure to
change “Destination settings” to different folder to prevent losing original
image as no option to rename
Only
effect is “convert to greyscale’ which reduces size
even more.
VSO Image Resizer http://www.vso-software.fr/products/image_resizer/image_resizer.php
Have to create “profile” for sized not listed. Does add size to
name to leave original
Compression only fair but bad if doing more
that one as closes after doing job. Not recommended.
Picasa – I did not find it friendly for the basic user. Not easy to open one image and I could not
find a resize so not included.
Several of these are also downloadable at http://www.snapfiles.com/Freeware/gmm/fwgcomp.html

ONLINE IMAGE RESIZING
Online Image
Resizer - http://resizeimage.4u2ges.com/
Good that after entering one dimension, click elsewhere
and it converts aspect ratio. It has
some quality settings too. Also shows and tells result before saving. Best of
several I found online and compares with the better programs in ease of use
and results.
ShrinkPictures.com http://www.shrinkpictures.com/
It does give choices of - set sizes, %, custom;
3 quality settings, and greyscale or Sepia effects.
The results in the charts are the middle one “better” of
quality choices. Results not
impressive.
The cool thing about this site is the information it gets from the photo
Example: the 314 pixel of test photo –

Has some effects, including “Border” styles but be careful
to set as pixels, even on the “optional” height, for correct size and to
prevent distortion

For images not needing resizing but just file compression,
online.
There are other programs for compression.
