PhotoRazor 2.5 makes high quality copies of your photos at a smaller size so you can share easily. It does not overwrite the original photos which you may need for printing the photos. PhotoRazor saves the smaller resized copies to a separate folder.
There is a trick to setup the size more then 600px. The slider only go up to 600px but you can use textbox to make it larger. I was confused when I used it for the first time.
PS: My brother-in-law shown me this too long time back and I started using it. I am a big fan of this tool now and would like to share with others.
