FAQs
How does this tool isolate the subject from the background?
Pixelora uses customizable focus coordinates (X and Y) with a radial feathering mask, keeping the designated focal region sharp while progressively applying Gaussian blur to surrounding background areas.
How do I position the sharp focal region on my subject?
Use the Focus X and Focus Y sliders in the tool panel. For example, if your subject is standing on the left side of the frame, set Focus X to approximately 30%.
Can I control how blurry the background appears?
Yes. The blur radius slider allows you to choose anything from a gentle lens softening (5px) to a dramatic dreamy bokeh blur (30px+).
What formats can I save the portrait photo in?
You can download the finished portrait as JPEG, PNG, or WebP at customizable quality settings.
Is my personal portrait private during processing?
Yes. All radial blur and masking calculations occur 100% locally on your machine inside your browser.
