A solution that has an unequivocal name, this is a free web-hosted service that might get you out of trouble when you least expect it. Through the site, you can upload any picture and proceed to modify its size until you obtain what you are looking for.
The mechanics of the site can be more or less described as follows. You choose a picture, you upload it, and then you alter its size. In order to do so, you can have your pick from three main options – “Small”, “Medium” and “Large”. For its part, an “Original” option is included for you to go back to where you started from if something went haywire and you have to start from scratch again, without having to repeat the whole upload process.
On the other hand, an advanced editor is provided in the event you wish to handle the task at hand as minutely as possible. In any case, the current file size is highlighted so that you can have a good idea of how much will the finished piece amount to.
Once the editing process is done, you simply save the file and download it to your desktop. Easy, simple, but very effective nonetheless.
