A dead simple application, Make A Thumbnail does exactly what its name suggests: generate a thumbnail from any picture that you have around. Using this site is as simple as uploading the image that you want to have minimized, and picking the exact size for the application to work its magic.
Four different thumbnail sizes are provided: 100 x 100, 150 x 150, 200 x 200 and 300 x 300. And if you have no idea which one would work out best for you, then that is not ba problem. Since you can create as many thumbnails as you want (Make A Thumbnail can be used for free), it is possible to generate one in each size and see which would suit your needs best.
And the site is not only free to use, it can also be employed without having to create an account or anything like that. Things are kept definitely simple here.
