Questions, answered.

How is this different from grayscale?⌄

Thresholding has only black and white. Grayscale retains intermediate gray levels and more tonal detail.

No. Images are processed on your device. Your image files are never sent to a server.

Will my original file change?⌄

No. Export creates a separate file and leaves your original unchanged.
