Rsizr is a Flash application that lets you resize JPG, PNG, and GIF images on your computer. With rsizr, in addition to normal image rescaling and cropping, you can also resize images using a new image resizing algorithm called seam carving (a method of image retargeting) that tries to keep intact areas in your image that are richer in detail.When you first come to rsizr.com, you will see a large folder icon in the center of the window. Click on this icon and a file browser will pop up. Choose any JPG, PNG, or GIF image from your computer and open it. Due to restrictions in Flash, neither the image width or height can exceed 2880 pixels.
Seam carving is a brilliant image resizing technique pioneered by Shai Avidan and Ariel Shamir. For their rockstar YouTube video and paper, click here.
