Does it reduce image quality?

The internal processing is lossless. The download is PNG which is lossless, so there is no quality loss regardless of how many adjustments you make.

What does the Invert toggle do?

It performs a classic photo negative — each channel value is subtracted from 255. Black becomes white, white becomes black, and all colours flip to their complementary colours.

What is the Warmth slider?

Warmth shifts the colour temperature. Positive values increase red and reduce blue (warmer, golden tones). Negative values do the opposite (cooler, blue tones).

Does Night Mode make a photo look like it was taken at night?

The Night Mode preset reduces brightness and shifts warmth cool, giving a dark muted look. It is a stylistic filter, not an AI day-to-night conversion.
