Frequently Asked Questions
How does the blur effect work?
Vizua applies a box blur algorithm that averages pixel colors within a configurable radius. Higher intensity values produce a stronger blur effect.
Can I blur just part of an image?
This tool applies blur to the entire image. For selective blurring (e.g., blurring a face or license plate), use a dedicated photo editor.
What blur intensity should I use?
For a subtle soft focus, try 3-5. For privacy blurring (hiding text or details), use 10-20. The maximum is 20.
