HDRU to XBM Conversion: FAQ

What are HDRU files?

HDRU is a rare image format associated with a currently obsolete image handling program called Apollo HRDU. HDRUs are considered old and uncommon, and are difficult to open with regular image viewers, but in case you found one it's probably best to convert to a more accessible extension, such as JPG or PNG.

What are XBM files?

The XBM (X BitMap) format represents a monochrome image file usually used for storing cursor and icon bitmaps in the X graphical user interface.
