    Hi Group,
    Is there a free software program available that will allow me to crop photos
    without the resulting photo being degraded?

    Thanks,
    Brigitte

  3. Brigitte,

    In most cases image degradation is not due to the software used for
    cropping, but the image file format. When you edit photos, do NOT use
    JPEG, because it is compressed each time you save it, losing quality.
    If you use non-compressed formats such as TIFF or PSD, the software
    should not matter--they will not degrade.

    JPEGCROP is freeware that uses a GUI front end to JPEGTRAN. It performs
    lossless cropping of JPEG images (i.e without re-encoding the image after
    the crop operation).

    Do remember though that when you crop you are throwing away pixels, so
    the resolution will reduce!

    Charlie,

    Thanks for this. Something I really have to study up on. Good
    question, Brigitte.

    Correct. But utilities like jpegcrop will not introduce any additional
    compression artifacts as a result of having cropped and saved the file.
