Image Chromatic Aberration Effect settings
Choose a non-zero whole-pixel channel displacement from 1 to 24 pixels; larger values create wider red and blue fringes.
Create the channel-offset PNGThe source is not overwritten. Export creates a separate channel-offset PNG.
Keep this page open until the download begins.01No server upload
The selected image is decoded and re-encoded inside this browser tab.
02Working copy released
After download, the preview URL, decoded bitmap, canvas, and selected source reference are cleared.
03Your download remains
Nirmion cannot remove the finished file from your device or browser download history.
Workflow guide
Use image chromatic aberration effect with an inspectable review path
Red samples shift left and blue samples shift right by a bounded whole-pixel distance, with edge coordinates clamped to the canvas. Compare the result with the untouched source before using it downstream.Social-ready choices
Build a glitch-style campaign derivative while checking coloured fringes around logos, faces, and high-contrast typography.
What you receive
Download a separate channel-offset PNG; the original file on your device remains unchanged.
Decision guide
What image chromatic aberration effect measures or changes
Red samples shift left and blue samples shift right by a bounded whole-pixel distance, with edge coordinates clamped to the canvas.
This stylized channel displacement does not simulate a measured lens, wavelength-dependent optics, demosaicing, or camera calibration. Browser-local processing avoids a Nirmion file upload, but it cannot remove copies stored elsewhere.
MDN Canvas pixel manipulationUseful checks for image chromatic aberration effect
- Build a glitch-style campaign derivative while checking coloured fringes around logos, faces, and high-contrast typography.
- Create a bounded review result while retaining the original for comparison, correction, or a different method.
- Test representative flat areas, gradients, edges, text, transparency, and high-frequency texture before accepting the output.
Good to know
Important image boundaries
- Why might a PNG not become smaller?
- PNG is lossless and browsers do not expose a quality control for it. Choose WebP or JPEG when reducing file size matters more than exact lossless pixels.
- Are animated images supported?
- No. The workspace accepts still JPEG, PNG, and WebP files. Re-encoding an animated source would otherwise keep only one frame.
- What does clearing the file mean?
- Because processing is local, there is no Nirmion server copy to delete. The tab releases its working references after success; your downloaded output remains on your device.
Questions answered
Frequently asked questions
Does Image Chromatic Aberration Effect upload my image?
No. Supported JPEG, PNG, and WebP decoding, pixel inspection, transformation, and export run in your current browser tab. Nirmion does not send the selected image to its API for this workflow. The result is a separate derivative or JSON report, while the original file on your device remains unchanged and should be retained for comparison.
How does Image Chromatic Aberration Effect work?
Red samples shift left and blue samples shift right by a bounded whole-pixel distance, with edge coordinates clamped to the canvas. Fully transparent samples are excluded from numerical reports, while visual effects preserve source alpha. The method does not infer subjects, restore missing detail, calibrate a display, or develop raw camera data. Compare edges, gradients, text, texture, and transparent areas with the original before relying on the result.
What are the limits of Image Chromatic Aberration Effect?
This stylized channel displacement does not simulate a measured lens, wavelength-dependent optics, demosaicing, or camera calibration. The workspace accepts one supported still image up to 20 MB and caps this pixel-intensive operation at 12 million decoded pixels for predictable browser memory use. Results depend on browser decoding and encoding support. Animation, raw development, ICC calibration, layer editing, and batch processing are outside this tool's verified scope.
