Picasa is marketed as being easy to use and it offers many one click effects such as color enhancement, red eye reduction and cropping. Other features include slide shows, printing and image timelines.

Pictures can be organized into albums. Albums can be organized into collections. Pictures can be rearranged in albums by drag and drop. Images can be resized and exported for external use, be e-mailed or printed. There is also an integrated facility to order photo prints.

One fundamental principle of Picasa is that it never overwrites original images. This means that any changes applied to images using Picasa are stored only as differences relative to the original file, and only appear within Picasa. To see any changes in other software, the user must Export the images.
