    About the Auto Fix Photo tool

    The fix analyzes each photo individually. It stretches the tonal range so blacks are black and whites are white, removes color casts such as the yellow of indoor lighting or the blue of shade, adjusts exposure toward a natural mid-tone and adds a gentle contrast curve.

    Corrections are deliberately limited, so a sunset stays warm and a moody photo stays moody; the goal is a natural look, not a filter.

    Frequently asked questions

    What does auto fix change?

    Brightness and exposure, contrast, white balance (color casts) and a very slight boost in color. Nothing else in the photo is altered.

    Can I make the correction weaker?

    Yes. The strength slider blends between your original and the fully corrected photo. 50% gives a subtle improvement.

    Does it work on many photos at once?

    Yes. Add up to 50 photos; each is analyzed and corrected separately, and you can download them all as a ZIP.

    Are my photos uploaded?

    No. All processing happens on your device in the browser. Your photos are never sent anywhere.
