How do I convert a PNG to DRF step by step?

Upload your PNG file to the converter, choose the 256-color palette option (or keep the adaptive default), turn on dithering if the image has gradients, then click Convert. Download the resulting .drf file and open it in Dr. Halo or any compatible DRF viewer.

Why would I convert PNG to DRF instead of keeping PNG?

DRF is the native palette-based bitmap format used by Dr. Halo and other legacy DOS graphics programs. Converting PNG to DRF lets you open modern images in those systems, and the indexed 256-color palette often creates a much smaller file than a 24-bit PNG while staying visually recognizable.

What PNG data is preserved when converting to DRF?

PNG alpha transparency, ICC color profiles, and 24/32-bit pixel depth are not preserved. The conversion flattens transparency onto a background color (usually white), quantizes all colors to a 256-color DRF palette with optional dithering, and discards metadata. Pixel dimensions stay the same, but color and alpha information is reduced.

PNG-TO-DRF

PNG loses its alpha and 24-bit color when converted to DRF: output is a 256-color indexed bitmap with dithered gradients for Dr. Halo compatibility.
