Many times when you want to put images on the net they are not compressed and so have a large file size.
For example the images at the top of the page that I have added I always compress to make as small as possible.
Sometimes however if I am not at home I can't reduce an image down using my own programs.
This is where this interesting online tool comes in. Save the image to your computer then find it and upload it to this site, it will compress it down
to a smaller size so you can then email it, post it, whatever with an easier to download size.
