About the AI Person Background Remover
Remove the background of a person photo with locally running AI segmentation. A pretrained TensorFlow.js BodyPix model detects human silhouettes, keeps those pixels and makes the remaining photo transparent. This tool is designed for one or more people, not product photos or animal portraits.
Formula or method
The browser downloads a pretrained MobileNet-based BodyPix segmentation model and runs inference on a scaled copy of your chosen JPEG, PNG or WebP image. The predicted person/background mask is applied to the image alpha channel and a transparent PNG is generated locally.
Worked example
Choose a photo showing a person against a busy wall, set a detection threshold of 0.65 and select Remove background. Check the output and save the transparent PNG for a presentation.
How to use the tool
- Choose a photo with clearly visible people under 8 MB.
- Allow the browser to download the AI model and process the image locally.
- Inspect the cutout and download the transparent PNG.
Common uses
People portraits, profile photos and presentation slides.
Assumptions and limitations
This is AI person segmentation only. It is not suitable for pets, products, vehicles or generic photo objects. Hair edges, overlapping people and transparent accessories may be imperfect. The model has an Apache-2.0 license and its weights must be downloaded from a model-hosting service. The photo itself is not uploaded.
Frequently asked questions
Can this AI remove backgrounds from product or pet photos?
Not reliably. The BodyPix model detects people. Use a differently trained and appropriately licensed segmentation model for arbitrary objects.
Privacy and support
Your photo stays on your device. The browser downloads TensorFlow.js model weights from an external host on first use, then processes the photo locally. ToolMosaic does not upload or store your photo.
