Frequently Asked Questions
Is grayscale the same as black and white?
In digital imaging, yes — “black and white” typically means grayscale, with 256 shades from pure black to pure white.
Can I convert back to colour?
No — colour information is discarded. Your original upload is untouched, so re‑upload the colour version if needed.
Does grayscale reduce file size?
Usually yes. Grayscale images store one channel instead of three, so files are typically 50–70% smaller in lossless formats.
Does it work with transparent PNGs?
Yes. Transparency is preserved; only the visible pixels are converted to grayscale.
