Automatic subject mask
A local ONNX model identifies the main foreground without manual tracing.
Cut out the main object and export it on a transparent background without uploading the photo.
About this tool
Separate the main subject from its surroundings and export a transparent PNG. The segmentation model runs locally after its first download.
A local ONNX model identifies the main foreground without manual tracing.
Inspect the cutout over a checkerboard before accepting the result.
The model processes the image in browser memory; only the model file is fetched.
Use a subject with visible edges and reasonable contrast from the background.
The first run loads the local model, then generates the transparent preview.
Check fine edges and save the cutout as a transparent PNG.
PNG
People, animals and products with a clear foreground/background boundary generally work best; hair, glass and similar colors are harder.
The browser must download and initialize the segmentation model once before it can process the image locally.
Images are processed in browser memory and are not uploaded. Only settings you explicitly save remain on this device.
