Image RGB Channel Balancer
Scale red, green, and blue channels independently with bounded gains, preserve alpha and dimensions, and export in the browser.

Adjust each channel from -100 to +100; zero preserves it, positive values amplify it, and negative values reduce it. Processing stays in this browser tab.

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 rgb channel balancer with a reversible review path
Three independent gain controls multiply decoded red, green, and blue values before each channel is clamped to the output range. Compare the derivative with the untouched source before using it downstream.Social-ready choices
Test a manual colour-balance derivative for a scanned illustration while comparing neutrals and saturated areas with the source.
What you receive
Download a separate RGB-balanced image; the original file on your device remains unchanged.
Decision guide
What image rgb channel balancer changes
Three independent gain controls multiply decoded red, green, and blue values before each channel is clamped to the output range.
Independent RGB gains are not automatic white balance, colour-chart calibration, selective colour editing, or ICC profile conversion. Browser-local processing avoids a Nirmion file upload, but it cannot remove copies stored elsewhere.
MDN Canvas pixel manipulationUseful checks for image rgb channel balancer
- Test a manual colour-balance derivative for a scanned illustration while comparing neutrals and saturated areas with the source.
- Create a review derivative while retaining the original for correction, comparison, or a different export.
- Test the operation on representative shadows, midtones, highlights, edges, text, and transparent areas.
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 RGB Channel Balancer upload my image?
No. For supported JPEG, PNG, and WebP inputs, decoding, pixel transformation, canvas rendering, and export run in your current browser tab. Nirmion does not send the selected image to its API for this workflow. The output is a new derivative, while the original file on your device remains unchanged and should be retained for comparison or later editing.
How does Image RGB Channel Balancer change pixels?
Three independent gain controls multiply decoded red, green, and blue values before each channel is clamped to the output range. Existing alpha values are preserved. The operation does not infer subjects, recover clipped detail, calibrate a display, or develop raw camera data. Inspect fine edges, gradients, text, skin tones, and transparent pixels in the exported file before relying on the result.
What are the practical limits of Image RGB Channel Balancer?
Independent RGB gains are not automatic white balance, colour-chart calibration, selective colour editing, or ICC profile conversion. 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. Output depends on browser decoding and encoding support. Animation, raw development, ICC calibration, layer editing, and batch processing are outside this tool's verified scope.
