Scaled to the photo: the same blur looks alike on a small or a large image.
How to blur the background of a photo
- Drop a portrait with one clear subject: a person or a pet.
- The model finds the subject in a few seconds. Drag the slider to compare.
- Set the blur strength, add black and white if you like, then download the JPG.
Questions
Is my photo uploaded?
No. The AI model downloads once to your browser and runs there. The photo is processed on your device and is never sent anywhere.
Is this real depth of field?
No. A camera with a wide aperture or a depth sensor measures real distance. This tool estimates the subject from one image and blurs the rest, so hair, glasses or objects that overlap the subject can look less natural at the edge.
Why is the first run slower?
The first time, your browser fetches the runtime and the model, about 16 MB before compression. After that they are cached, and the tool works offline.
Does it keep the full size?
Yes. The JPG has the same width and height as the photo. If your device cannot process a very large photo, it is reduced to fit and the tool says so.
