What is the quickest tool that can let me choose a rectangle (of a predefined size) within any picture file, and it should crop it to that. Something like the tool you get when uploading a Gravatar ... remember?
Typical image editing software like Paint.NET or Photoshop is too slow, you have to open the image file, select a rectangle manually, crop, save, close ....
There is JPEGCrop, which is a Windows GUI application for most of the jpegtran features:
A new -crop option has been added to jpegtran for 'lossless' cropping of JPEG images:
-crop WxH+X+Y Crop to a rectangular subarea
I made a free tool to do that:

Just select the part of image you want to crop and press X to crop or Z to crop and go to the next image.
my tool of choice:
PhotoFiltre, dead fast, free and portable.
I use MSPaint for this, and it's pretty quick. It's almost a reflex.
The fact that it loads quickly and is available on any (windows) machine you use makes it particularly appropriate.
After a lot of searching and evaluating, i eventually found a tool called "Click 2 crop". Its simple and dead fast for manual cropping. It have the options you are asking for. Its not free but offers a 15 day evaulation.
If you have microsoft office it's quick and easy: 'Open with' Microsoft Office Picture Manager, Click 'edit pictures' at the top, A window will open to the right with 'crop'
There are lot of online tools to do that quickly: http://www.cutmypic.com http://www.cropmyimage.net
It doesn't get any simpler than in Google's Picasa.
Draw the box, hit the button and you are done.
Be aware that Picasa does not make permanent changes to the image - it stores the edits and re-applies them when you view the image.
If you want to send the cropped image, or view it in another app, you would export a copy of the image.
