GIMP
is a good idea to save image stages under different names or make backups in
another directory so you can easily restore a previous state.
When saving for the first time or using ‘Save as’, a dialog opens in which to
specify the file name and type. The current directory in shown in a box centered
above the two columns. Select another directory by double-clicking it in ‘Folders’.
To save the image as an existing file, select it in ‘Files’. Otherwise, enter a new
name in the field at the bottom. It is recommended to leave ‘Determine File Type’
set to ‘By Extension’. With that setting, GIMP determines the file type based on
the extension appended to the file name. The following file types are frequently
useful:

XCF
This is the native format of The GIMP. It saves all layer and path informa-
tion along with the image itself. Even if you need an image in another for-
mat, it is usually a good idea to save a copy as XCF to simplify future modi-
fications. Information about layers is available in Layers on page 248.

PAT
This is the format used for GIMP patterns. Saving an image in this format
enables using the image as a fill pattern in GIMP.

JPG
JPG or JPEG is a common format for photographs and web page graphics
without transparency. Its compression method enables reduction of file
sizes, but information is lost when compressing. It may be a good idea to
use the preview option when adjusting the compression level. Levels of 85
percent to 75 percent often result in an acceptable image quality with rea-
sonable compression. Saving a backup in a lossless format, like XCF, is also
recommended. If editing an image, save only the finished image as JPG. Re-
peatedly loading a JPG then saving can quickly result in poor image quality.

GIF
Although very popular in the past for graphics with transparency, GIF
is less often used now because of license issues. GIF is also used for ani-
mated images. The format can only save indexed images. See Image Modes on
page 249 for information about indexed images. The file size can often be
quite small if only a few colors are used.

PNG
With its support for transparency, lossless compression, free availability,
and increasing browser support, PNG is replacing GIF as the preferred
format for web graphics with transparency. An added advantage is that
PNG offers partial transparency, which is not offered by GIF. This enables
smoother transitions from colored areas to transparent areas (antialiasing).
