Free Ai Background Blur Tool — No Limits, No Upload
Apply professional bokeh background blur to any photo using AI subject detection. imgavio processes everything locally in your browser using WebAssembly technology — your images never leave your device at any point. This gives you the privacy of desktop software with the convenience of an online tool.
Unlike tools such as iLoveIMG, TinyPNG, or remove.bg that send your files to their servers, imgavio's AI background blur tool works entirely on your device. This means: no waiting for uploads, no privacy risks, no file size restrictions, and no slowdowns from server queues.

Creating Professional Portrait Photography
DSLR photographers achieve background blur (bokeh) by using wide aperture lenses (f/1.2, f/1.8) that create a shallow depth of field. Smartphones now simulate this with portrait mode using computational photography. imgavio brings the same capability to any photo, regardless of how it was taken.
Frequently Asked Questions
-
What is bokeh effect?Bokeh is the aesthetic blur applied to out-of-focus areas in photographs, created naturally by cameras with large aperture lenses. imgavio simulates this effect digitally using AI to separate subject from background.
-
How accurate is the subject detection?The AI model is trained specifically for portrait and object segmentation, achieving excellent edge accuracy especially for people, animals, and products.
-
Can I control the blur intensity?Yes. The blur strength slider goes from subtle (1x) to extreme (20x).
-
Does it work on group photos?Yes. The AI detects all people or subjects in the frame and keeps them sharp while blurring the background.
-
Can I apply different blur effects?Yes. Choose from Gaussian blur (smooth and natural), bokeh simulation, or radial blur (depth of field style).
-
Does it work for product photography?Yes. Products are detected and kept sharp while the background is blurred for a clean studio-style look.
-
Is the output quality maintained?Yes. The full resolution image is processed with no quality reduction.
