Convert, rename, resize, adjust contrast, and much more with many photos all at once with FastStone’s Photo Resizer. Occupying only ~1Mb of disk space this tool is perfect for your computer or to carry around on a flash drive. Did I mention it is free!? I use it to convert, lighten, rotate, and resize photos when I need to send people notes that I have "photo-scanned."

FSResizer allows the user to convert any image into a JPG, GIF, PNG, BMP, TIFF, or JP2 file. Simply specify what you want to do and what the output format should be and where it should go and hit Start. It processes the images quickly and accurately.

The "Advanced Options" menu provides a list of options to add to the process and includes a preview window of the picture when trying to adjust the contrast or brightness.

Of course, if you are professional photographer you probably have Photoshop or CS3 or equivalent that might do this for you. However, FSResizer’s quick and easy to use interface makes this a tool for all.

Need to resize those giant pictures that you have so that they can send in email? Resize them, adjust the quality if necessary, and hit Start to produce small email-able files that still look decent.

Check out FSResizer and put it on your flash drive for those quick converting needs. FastStone offers many other awesome products.
