  1. What are the system requirements?
    • Intel Pentium III / AMD Athlon XP
    • 512 MB RAM (2 GB recommended)

    Operating system:
    • Windows 10 / 8 / 7 / Vista / XP (SP3)
    • 32 or 64 bit

  2. I don't want to resize. How do I just change the image format?
    Select the second profile from top, called <Original Resolution>. Then in the General options, select the format you want to convert to.

  3. How do I output my images to a subfolder of the original folder?
    As Destination enter a dot, followed by a backslash, and then the folder name, e.g.: .\Resized

  4. Why does Light Image Resizer create .bak files?
    By default, backups are created whenever files are overwritten in the current version. This behavior can be turned off via settings (see Processing tab).

  5. How do I get correct dimensions for images in portrait and lanscape mode?
    Light Image Resizer will take care of the orientation for you, if you enable "Adjust resolution for portrait" on the Misc tab (under Advanced).

  6. Is it possible to use the same date of the original file?
    Yes, enable the option "Keep original file date" on the Misc tab (under Advanced).

  7. How can I select color space or color depth for my images?
    Make sure that one of the following image formats is selected (see section Advanced > General > File Type):
    • Bitmap (BMP)
    • JPEG
    • PNG
    • TIFF

    If one of the above formats is selected, the Colors option will allow you to select your preferred color depth (for BMP and PNG), or color space (for JPEG and TIFF).

  8. I can't start processing because of the "Recreate folder structure on destination" option?
    If this option is enabled, you need to specify a full path (e.g. C:\Pictures\Christmas). If you want to overwrite originals, just disable "Recreate folder structure on destination" (see Settings, General).

  9. Why doesn't Light Image Resizer ask for a profile name when saving?
    Earlier versions had a different behavior when saving a profile. If you want to create a copy of an existing profile, see the next question.
