Black and white: common questions
How is black and white calculated?
From each pixel’s luminance (more weight on green, as the eye perceives it), not a plain average, so tones look natural.
Can I just raise the brightness?
Yes: choose “Original colour” and move brightness, contrast or saturation.
Is quality lost?
The photo keeps its size and is saved at high quality. PNG transparency is kept.
Are my images uploaded to a server?
No. The tool runs inside your browser: files are read and processed on your device and are not sent to Cocuyo or to any third party. You can check it in your browser’s network tools: your file is not sent.
Is it really free?
Yes. You can try it before signing up; to download the result we ask for a free account, with no subscription. Your free account comes with 30 welcome uses; after that, each use costs 1 credit (top-ups from US$1), and they are unlimited with Basic or Pro. It never adds a watermark.
What are the limits?
JPG, PNG or WebP up to 30 MB and 40 megapixels per file, not animated. Files are processed one at a time so the tab stays responsive, even on a phone.
