FAQ
Does converting to B&W lose original detail?
Processing creates a new file from the original — the original is not modified. JPEG adds slight compression; PNG is lossless.
What is grayscale strength?
100% is full black-and-white, 0% is the original color image; values in between keep some color for a look between color and B&W.
Are my images uploaded to a server?
No — everything runs locally in your browser, so your images never leave your device.
