Is the Red-Eye Remover free?
Yes. The Red-Eye Remover is free to use with no account and no watermark on the exported photo.
Does this upload my photo to a server?
No. The correction and export happen entirely in your browser, so your photo stays on your device the whole time.
Does it automatically find faces or eyes?
No. Targeting is manual: you click the center of each eye that needs correction, then export the result. This keeps you in full control.
What file types does it support?
The Red-Eye Remover works with JPG photos and exports a corrected JPG, the common format for flash photos that show red eye.
Can I adjust how strong the correction is?
Yes. You can adjust both the correction radius and the intensity before exporting, so you can match the size of the red area and how much it is reduced.
Why does the correction sometimes miss part of the pupil?
Because a pixel has to be measurably red to be touched. The test is that the red channel exceeds 1.08 times the mean of green and blue. If the flash reflection has blown out to near white, red, green, and blue are all high and the ratio never crosses the line, so that pixel stays. Raising the intensity does not help there. The blown-out core needs a paint tool, not a red-eye filter.
What happens if I make the circle too big?
Very little. Only red-dominant pixels inside the circle are corrected, and the strength falls off toward the circle's edge, so a radius that overlaps the iris, the eyelid, and some skin still only touches the red glow. A radius that is too small is the more common mistake, because it leaves a bright ring around a corrected center.
Does the fix change the rest of the photo?
Only through re-encoding. Pixels outside your circles are copied through untouched, but the whole image is re-saved as a JPG at 90% quality, which is one extra generation of lossy compression. If you are editing a keeper, work from the original file rather than a copy that has already been saved several times.
Can I fix red-eye in a photo of a group?
Yes. Click each eye in turn and each click becomes its own point with its own radius, so you can use a wide circle for the person in front and a small one for someone in the back row. All the points are applied in a single pass when you run the correction.
Does my photo get uploaded anywhere?
No. The JPG is decoded, corrected, and re-encoded inside the page on your own device, which matters because red-eye photos are usually pictures of family and children. The only network call is a credit counter carrying the tool name.
