Can it fix the green or yellow eyes in pet photos?

No. This tool only reduces red — it pulls down the amount by which red exceeds green and blue — and ignores green or yellow reflections. Pets have a reflective layer behind the retina that bounces back green or yellow under flash; recolour that patch by hand in the full editor («Pro editor», top right). It doesn't recognise eyes either: reddish skin inside the brush circle gets reduced too, so keep the brush not much larger than the pupil.

Will the pupil turn into a flat black blob?

No. Only the red channel is reduced, so the pupil keeps its original shading and the highlight on the eyeball stays — it still looks like a real eye.

Do I need an account? Is it paid?

Neither. Free, no sign-up, no usage cap, and no watermark.

Is my photo uploaded?

No. The whole thing runs in your own browser — we never receive the file.

Red-eye shows up in essentially one situation: indoors, low light, direct flash. The camera's pre-flash often doesn't get there in time, and by the time you notice, the people have scattered and the moment is gone — so it's a fix you make afterwards, and happily it's one of the easiest flaws to fix well.

Red-eye is the flash lighting up the blood vessels at the back of the retina. The fix is not to paint it black — that leaves a dead hole where the eye was. Here only the amount by which red exceeds green and blue is pulled down, so the pupil keeps its original shading and the catchlight stays put, and it still reads as an eye. Everything runs in your own browser and the photo is never uploaded. It only reduces red and ignores green or yellow reflections — the green and yellow eyeshine pets get under flash needs manual recolouring in the full editor («Pro editor», top right). It doesn't recognise eyes either: reddish skin inside the brush circle gets reduced too, so keep the brush not much larger than the pupil.
