About the Red Eye Remover
Red eye happens when a camera flash lights up the back of the eye through wide-open pupils. This tool fixes it in a few taps: tap the centre of each red eye and the strongly red pixels inside a small circle are turned back into a natural dark pupil, with a soft edge so the result blends in. Skin, eyelashes and the coloured iris are left alone because only clearly red pixels change. Adjust the circle size, undo any tap, and download the corrected photo at full size. The photo never leaves your device.

Getting a natural result
Make the circle just larger than the red area, then tap its centre. For close-up portraits use a larger circle; for group photos with small faces, a circle of 1 to 2% of the photo is usually right. If one tap isn't enough, tap again on any remaining red; each tap only darkens red pixels.
How the correction works
For each pixel in the circle, the tool measures how much redder it is than its green and blue. Strongly red pixels have their red brought down to the level of the other channels, which leaves a dark, neutral pupil while keeping the catch-light reflection. The effect fades towards the edge of the circle so there's no visible ring.
Avoiding red eye next time
A few simple habits prevent it.
- Turn on more room lights so pupils are smaller
- Use the camera's red-eye reduction pre-flash
- Bounce the flash off a ceiling, or move it away from the lens
- Ask people not to look straight into the flash
Group photos
Zoom in with two fingers on a phone before tapping small eyes, then tap each eye in turn. The counter shows how many fixes you have made, and Undo removes the last one.
When red eye is very strong
In some flash photos the whole pupil is bright orange or pink, almost white in the middle. The tool darkens all clearly red and orange-red pixels, but very pale centres may stay light. Tap again with a slightly smaller circle on the remaining area, or accept a little brightness: real eyes have a catch-light reflection, and a completely black pupil can look unnatural.
Saving and sharing
The download keeps the original file type where possible: PNG photos are saved as PNG and everything else as a high-quality JPG with -red-eye-fixed added to the name, so your original file is never overwritten.
Phone and computer
The photo fills the screen on a phone so eyes are easier to tap. On a computer, click with the mouse; the result is saved at the original size either way. Red eyes are one flaw, and the rest of the photo may need work too. Use the Photo Editor for general fixes, Crop Image to frame the face, and Sharpen Image to bring back detail.

Frequently asked questions
What causes red eye?
In dim light pupils open wide, and the camera flash reflects off the blood-rich retina at the back of the eye straight into the lens.
Will it change the colour of the iris?
No. Only pixels that are clearly red change, so blue, green and brown eyes stay as they are.
Why didn't anything happen when I tapped?
The circle may have missed the red area, or the red may be too pale. Tap the exact centre, or make the circle a little bigger.
Can it fix pets' eyes?
Pets usually get green, yellow or white eye shine instead of red, which this tool doesn't change, because it only targets red.
Does it lower the photo quality?
Only the pixels inside the circles change. JPG photos are saved again at high quality, and PNGs stay lossless.
