Technical note

KRO to JPEG: what carries over and what does not

KRO carries 16 bits per channel and JPEG carries 8, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to an 8-bit format only at the very end. KRO stores pixels without compression loss and JPEG does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.

FAQ

KRO to JPEG Conversion

What are KRO files?

KRO (Kolor Raw) is a simple, uncompressed image format created for the Kolor software, best known for its Autopano panorama stitching programs. Panoramas can be gigantic, and many common formats cannot hold pictures larger than about 30,000 pixels on a side, so the authors designed a format without such a limit. It stores color pictures with 8 or 16 bits per channel, or with floating-point numbers for high dynamic range images, with or without transparency. Because the pixels are saved without any compression, files are large, and the format is intended for temporary work between stages of processing rather than for sharing finished pictures. The panorama publishing tools of krpano can also read and write it.

What are JPEG files?

JPG or JPEG is a commonly used method of lossy compression. JPEG compression is used in a number of image file formats.
