Image Radial Blur Effect
Average RGB samples along short rays toward the image centre to create a repeatable centre-directed blur with source alpha retained.

Image Radial Blur Effect settings
Choose 1 to 20 samples along each centre-directed ray; more samples create smoother averaging.

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 radial blur effect with an inspectable review path
Each output samples several positions along a twelve-percent ray toward canvas centre and averages RGB without moving output alpha. Compare the result with the untouched source before using it downstream.Social-ready choices
Create a restrained zoom-like treatment for authorised campaign art while checking the centre, corners, text, and subject edges.
What you receive
Download a separate centre-directed radial-blur PNG; the original file on your device remains unchanged.
Decision guide
What image radial blur effect measures or changes
Each output samples several positions along a twelve-percent ray toward canvas centre and averages RGB without moving output alpha.
This geometric sampling is not lens blur, depth-aware bokeh, camera motion recovery, optical calibration, or detail restoration. Browser-local processing avoids a Nirmion file upload, but it cannot remove copies stored elsewhere.
MDN Canvas pixel manipulationUseful checks for image radial blur effect
- Create a restrained zoom-like treatment for authorised campaign art while checking the centre, corners, text, and subject edges.
- 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 Radial Blur 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 Radial Blur Effect work?
Each output samples several positions along a twelve-percent ray toward canvas centre and averages RGB without moving output alpha. 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 Radial Blur Effect?
This geometric sampling is not lens blur, depth-aware bokeh, camera motion recovery, optical calibration, or detail restoration. 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.
