Frequently Asked Questions

How does the oil painting effect work?

For each pixel, the algorithm examines a radius R neighborhood, categorizes colors into intensity bins, finds the most frequent intensity level, and replaces the pixel with the average color of that bin. This creates the characteristic brush-stroke look.

Is Oil Painting Effect free?

Yes, PivaBox Oil Painting Effect is completely free. All processing runs locally in your browser using Canvas API — your images never leave your device.

What settings give the best results?

For a subtle effect, try Brush Size 4-6 with Intensity Levels 16-24. For a bold painterly look, use Brush Size 8-14 with Intensity Levels 8-12. Higher intensity levels preserve more detail.
