Image Normalizer is a cross-platform command-line batch-processing tool that resizes and compresses images, transforming each image by:
- removing its CICP, EXIF, ICC, IPTC and XMP profile data, if present
- resizing it to fit within the maximum width/height supplied, if necessary
- compressing it to the provided image quality level
- saving it in the JPEG format with the .jpg file extension
Image Normalizer is intended to support the storage of images produced by digital cameras in a consistent and disc space conserving manner.
Image Normalizer targets .NET 8 on Linux, Windows and macOS.
