What Blur Background does
Blur the background of a photo while keeping the subject sharp, using an AI mask that runs in your browser.
The browser decodes the image and performs the change on a Canvas. ToolkitPoint does not receive the pixels. For Blur Background, the operation is specifically to blur the background of a photo while keeping the subject sharp, using an AI mask that runs in your browser.
Worked example
A phone photo of a person in front of a busy street keeps the person sharp while the street behind becomes a soft blur, similar to a phone's portrait mode, without uploading the photo anywhere.
When Blur Background is the right tool
- Making profile photos and headshots look more professional.
- Hiding a messy room or sensitive details behind a subject.
How to verify the result

Important limitations
Browser decoding support varies by format. Re-encoding can remove metadata and may change color profiles or introduce lossy compression. This matters here because Blur Background is designed to blur the background of a photo while keeping the subject sharp, using an AI mask that runs in your browser, not to repair unrelated source problems.

Frequently asked questions
How does it know what to blur?
An AI segmentation model (RMBG, run with ONNX in your browser) estimates which pixels belong to the subject. Everything else is replaced with a blurred copy of the original photo.
Is my photo uploaded?
No. The model file is downloaded once and runs on your device; the photo never leaves it.
Why is the first run slow?
The AI model is a large download the first time and needs memory to run, so older phones may struggle. Later runs are faster.
What if the edges look wrong?
Use the erase and restore brush and the edge feather controls to fix hair, glasses or gaps before downloading.
Does it keep the full resolution?
Yes. The mask is made at up to 1024 px and then refined and applied to the original full-size photo.
