Chromatic Aberration Remover
Red and cyan or blue and yellow fringes along high-contrast edges can make sharp photos look soft. The Chromatic Aberration Remover realigns an image's red and blue channels horizontally by up to 20 pixels, giving photographers a quick fix for consistent sideways color fringing, with the corrected file saved as a lossless PNG.

Frequently asked questions
What does the Chromatic Aberration Remover do?
It reduces lateral chromatic aberration, the colored fringes that appear when a lens focuses red, green and blue light to slightly different positions. The tool shifts the red and blue channels horizontally in opposite directions by the number of pixels you choose, while leaving green untouched, so the three channels line up again. The corrected image downloads as a PNG named fixed-image.png.
How do I remove chromatic aberration from a photo?
Click the upload area or drop your image on it. When it loads, the Shift Intensity (Red/Blue Channel) slider appears, set to 2 pixels. Choose a shift from 0 to 20 pixels, then click Process Image to download the corrected PNG. There is no live preview, so zoom into a high-contrast edge in the result, then adjust and process again if needed.
What shift intensity should I use?
Start with 1 or 2 pixels. Most fringing in modern lenses is only a pixel or two wide, especially on downsized images. Higher values suit full-resolution files from older or wide-angle lenses with obvious fringes. If the result shows new fringes in the opposite colors, the shift is too strong, so lower it. A value of 0 leaves the image unchanged.
What kind of color fringing can it fix?
It works best on fringing that runs consistently in one horizontal direction across the frame, such as red and cyan edges on vertical lines. The same shift is applied to the whole image and only horizontally, so it does not address vertical fringes or purple halos around blown highlights, which come from a different lens effect and are better handled with defringing in a raw editor.
When does chromatic aberration show up most?
Look along high-contrast edges near the corners of the frame: tree branches against a bright sky, window frames in interiors, building edges and backlit hair. Wide-angle and older zoom lenses produce it most, and it becomes more visible when you crop or print large. Correcting it early in your edit keeps fine detail looking crisp in architecture and landscape work.
Is the Chromatic Aberration Remover free to use?
Yes. It is free, adds no watermark and needs no installation. Your photo is processed in your browser on your own device and is never uploaded. The first time, you confirm you are a photographer and create or log into a free Imagen account, which unlocks every tool. Imagen also makes AI editing software that learns your personal editing style.
