Why Convert BMP to PNG64 file?

PNG64 is a very high-color-depth version of the PNG format, storing 64 bits per pixel, while a standard BMP holds ordinary color. Converting BMP to PNG64 places your image into this lossless, high-depth PNG, useful when a professional workflow specifically expects deep-color PNG output.

Keep in mind that converting a standard BMP to PNG64 cannot add color depth the image never had; it provides the picture losslessly in the higher-depth container those workflows expect, in a larger file. For everyday viewing, sharing, and the web, a standard PNG is far more practical and compact. Reach for PNG64 only when a specific deep-color workflow requires it.
