Your photos will look better on Facebook if you resize them before you upload
Unless you are uploading photos from your iPhone or Android you should resize them before you upload to Facebook for the best quality. The optimum and recommended size for Facebook photos is 720 pixels and if you upload a larger file Facebook will resize it automatically. But, the quality of the resizing algorithm is not as good as in CorrectPhoto or Photoshop or Elements. Resizing is easy to do in either photo editor, although it is a bit easier and faster in CorrectPhoto. Here are simple resizing instructions for both CorrectPhoto and Photoshop Elements.
With the photo open in CorrectPhoto click on the resizing icon to the left of the OneClick Color icon. In the case of this photo I changed the “Width” to 720 pixels and the height changed proportionately. Click OK and Save the resized photo. The resizing algorithm in CorrectPhoto is very good a will preserve the quality of your photo.
