Portrait Background Blur
Choose a portrait, paint over the subject to protect it, and export a copy with the remaining background blurred. No automatic segmentation or upload is used.
Use the brush on the subject; unpainted areas are blurred.
A QUICK WALKTHROUGH
How to use this tool
- Choose a JPEG, PNG, or WebP image within the limits.
- Paint the subject mask with the brush, adjust blur, and review the preview.
- Export a new image after checking the subject edges and background.
Manual mask by design
This tool does not claim to detect people or subjects. You paint the area to keep sharp; unpainted pixels receive the blur.
Local canvas processing
The selected image and mask stay in this browser. Canvas export does not retain source metadata, ICC profiles, or animation.
GOOD TO KNOW
Common questions
Does it detect the subject automatically?
No. Paint the subject yourself so the boundary is under your control.
Is my image uploaded?
No. Decoding, masking, blur, and export happen locally in this browser.
