Frequently Asked Questions
Which conversion method should I use?expand_more
Luminosity (HDTV) is the most accurate for most photos, since it weighs colors the way human eyes perceive brightness. Average gives a flatter, more uniform look. PAL/NTSC is the classic formula used in broadcast television and older image processing software.
What does the intensity slider do?expand_more
At 100%, the image is fully desaturated. Lower values blend the grayscale result with the original colors, useful for a subtle, partially-desaturated effect.
Does this reduce image quality?expand_more
No, resolution is fully preserved. PNG output is lossless; JPG uses a high-quality setting to keep detail intact.
