How does image dehazing work?

The tool uses a dark channel prior algorithm. It estimates the haze density by finding the darkest pixel in small patches of the image, then subtracts the estimated haze layer to recover the original scene colors and contrast.

Does dehazing increase file size?

Yes, slightly. Dehazing adds local contrast and detail, which increases the amount of data in the image. Expect output files to be 10-30% larger than the input.

Will it work on indoor photos or portraits?

The algorithm is tuned for outdoor atmospheric haze. On indoor or portrait photos, high strength values may produce unnatural color shifts. Use low settings (20-30%) for subtle contrast enhancement only.

What output format does the tool produce?

Results are exported as JPG at 92% quality, which preserves fine detail while keeping file sizes reasonable.

Is there a size limit for uploaded images?

All processing runs in your browser. Images up to 20MB process fine on most devices. Very large images (50MB+) may be slow depending on your hardware.
