Frequently Asked Questions
Is the conversion lossless?
The color-to-grayscale mapping is deterministic and high quality. Exporting as PNG keeps every pixel, while JPG output applies normal JPG compression.
Why convert to grayscale?
Black and white images are often used for print, documents, artistic photography, and reducing file size where color is not needed.
