Frequently Asked Questions

Does my image get uploaded to a server?
No — everything runs in your browser using the HTML Canvas API. Your photos are never sent anywhere, stored, or seen by anyone.
What's the difference between Manual and Radial mode?
Manual mode lets you paint exactly which areas stay sharp using a soft brush. Radial mode automatically keeps a circular area in focus (great for portraits) with no painting needed.
Will the output be full resolution?
Yes. The on-screen editor works at a scaled-down resolution for speed, but when you click Download the tool processes your full-resolution original and outputs it at maximum quality.
Can I undo mistakes?
Yes — click Undo to revert the last brush stroke. You can also reset the entire mask with the Reset button, or switch to Erase mode to clean up specific areas.

Blur Image Background Online — Free Tool

A blurred background creates the professional "bokeh" effect that makes your subject stand out beautifully in photos. Our free blur background tool applies this effect instantly in your browser, perfect for portraits, product photos, and social media content.

💡 Subject detection

For best results, ensure good contrast between the subject and background. Well-lit photos with clear edges produce the most accurate blur.

💡 Adjust blur intensity

Light blur preserves some background detail for a natural look. Heavy blur creates a dramatic studio-style effect.

💡 Portrait photos

Blur works exceptionally well for portrait photography, drawing attention to the face and reducing distracting backgrounds.

💡 Product photography

E-commerce product photos with blurred backgrounds look more professional and are more effective than flat white backgrounds.

Background blur (also known as "bokeh" from the Japanese word for haze) is a photographic effect traditionally achieved with wide aperture lenses. Computationally, it is applied by detecting the subject using edge detection algorithms, creating a mask that separates foreground from background, and applying a Gaussian blur to the background layer only. Our tool performs this segmentation and blurring entirely in your browser using Canvas API operations, keeping your photos private and delivering instant results without server processing.
