10.3. Saving Files

There are several commands for saving images. A list, and information on how to use them, can be found in the section covering the File menu.

GIMP allows you to save the images you create in a wide variety of formats. It is important to realize that the only format capable of saving all of the information in an image, including layers, transparency, etc., is GIMP's native XCF format. Every other format preserves some image properties and loses others. When you save an image, GIMP tries to let you know about this, but basically it is up to you to understand the capabilities of the format you choose.

As stated above, there is no file format, with the exception of GIMP's native XCF format, that is capable of storing all the data in a GIMP image. When you ask to save an image in a format that will not completely represent it, GIMP notifies you of this, tells you what kind of information will be lost, and asks you whether you would like to "export" the image in a form that the file type can handle. Exporting an image does not modify the image itself, so you do not lose anything by doing this.

[Note] Note

When you close an image (possibly by quitting GIMP), you are warned if the image is "dirty"; that is, if it has been changed without subsequently being saved. Saving an image in any file format will cause the image to be considered "not dirty", even if the file format does not represent all of the information from the image.
