How to reduce blur in an image online
Upload an image, choose Motion Blur or Defocus Blur, adjust the restoration strength and refinement passes, and start processing. The image is sent to the server, where edge-preserving filtering and controlled sharpening are applied. Review the result before continuing to the download page.
Motion Blur mode
Motion mode applies bilateral filtering to reduce noise while retaining stronger edges, followed by conservative unsharp masking. This can make blurred edges look clearer, but it cannot reconstruct detail that was never captured in the original image.
Defocus Blur mode
Defocus mode uses a similar edge-preserving filtering process with a slightly broader sharpening comparison. It is intended for images that look generally soft or out of focus rather than images affected mainly by directional camera movement.
What the Strength control does
Strength controls how strongly the sharpening stage is blended into the processed image. Higher values can make edges appear more pronounced, but excessive sharpening may introduce halos, harsh transitions, or visible noise. Start with a moderate value and compare the result before increasing it.
What refinement passes do
Each refinement pass repeats the filtering and sharpening process. Additional passes can increase the visible effect, but they do not guarantee more recovered detail. Too many passes may exaggerate noise or edge artifacts, especially in already compressed or low-resolution images.
What this tool can improve
- • Soft-looking edges in mildly blurred photos
- • Moderate motion-related softness
- • Slight defocus blur
- • Images that benefit from controlled edge enhancement
What it cannot reliably recover
- • Detail completely lost to severe blur
- • Unreadable text that was never captured clearly
- • Missing facial or object detail
- • Information removed by heavy compression or clipping
Why sharpening is not the same as restoring lost detail
Sharpening increases local contrast around edges, which can make an image appear clearer. It does not recreate exact information that was lost when the photo became blurred. Results therefore depend heavily on the original image, blur severity, noise, compression, and the selected settings.
Tips for better unblur results
Unblur Image FAQ
Can this tool completely fix a blurry photo?
Not always. It can reduce the appearance of moderate blur and strengthen edges, but severely lost image detail cannot be reliably reconstructed.
What is the difference between Motion and Defocus mode?
Motion mode is intended for motion-related softness, while Defocus mode is intended for more general out-of-focus blur. Both use edge-preserving filtering and controlled sharpening with slightly different settings.
Should I use the highest strength?
Not necessarily. Higher strength increases sharpening and can also increase halos, noise, or harsh edges. Moderate settings are usually a better starting point.
Do more refinement passes always improve the result?
No. Additional passes repeat the restoration process, but excessive processing can introduce artifacts. Compare each result rather than assuming more passes are better.
Is the image processed in my browser?
No. The selected image and settings are sent to the server for processing.
What format is produced?
The current processing route creates a JPEG output image.
