How to Blur and Remove Background in Windows 11 Photos

The Microsoft Photos app in Windows 11 includes built-in, AI-powered editing tools that allow users to easily isolate, blur, remove, or replace the background of any image without requiring third-party software. This guide details the specific background editing features available in the app, their capabilities, and how you can use them to modify your photos directly within the Windows operating system.

Accessing the Background Editing Tools

To access these features, open any image in the Windows 11 Photos app and click the Edit image icon (or press Ctrl + E). In the editing toolbar at the top of the window, select the Background tab. The app will automatically analyze the image and detect the primary subject, isolating it from the background.

Background Blur

The Background Blur tool softens the area behind the subject to create a shallow depth-of-field or “portrait mode” effect.

• Automatic Detection: The app automatically creates a mask separating the subject from the background.
• Blur Intensity Slider: You can adjust the strength of the blur from subtle softening to a heavy bokeh effect using a dedicated slider.
• Selection Brush Tool: If the automatic selection misses any parts of the image, you can toggle the Selection Brush on to manually paint over areas to add or remove them from the blur mask. You can adjust the brush size and softness for precision.

Background Removal

The Background Removal tool completely erases the background from the image, leaving only the detected subject.

• One-Click Transparency: Clicking the Remove option immediately strips away the background, replacing it with a transparent canvas (checkerboard pattern).
• Exporting Transparent Files: Once the background is removed, you can save the edited file as a PNG to preserve transparency for use in graphics, presentations, or compositing projects.
• Mask Refinement: Like the blur tool, the Selection Brush remains available to clean up edges or include objects that the AI may have initially excluded.

Background Replacement

The Background Replacement feature allows you to swap out the original background for a solid color backdrop.

• Color Palette Selection: After selecting the Replace option, you can choose from a preset palette of solid colors to instantly fill the area behind the subject.
• Custom Color Picker: A full color spectrum and hex code input allow you to select any custom color, making it useful for creating professional headshots, ID photos, or product listings.

Manual Selection and Masking Controls

Across all background modes, the Photos app provides precise masking controls:

• Invert Selection: Inverts the mask so that the applied effect (blur, removal, or replacement) affects the subject instead of the background.
• Brush Size and Softness: Customizable brush parameters give you fine control when adjusting complex edges such as hair, clothing textures, or detailed foreground objects.
