What this tool is for
Remove backgrounds locally with a fast portrait model or a finer general model, then reuse the mask with transparency, a solid colour, or another image.
How to use it
Choose the fast portrait or detailed general model, allowing the first download and integrity check to finish. Review the alpha mask, then reuse it for transparent, solid, or custom backgrounds; hair and translucent edges still need zoomed inspection.
Results and next steps
The default result is a transparent PNG, or the same mask can be composited onto a solid or custom background. Zoom and compare before download.
Privacy and local processing
Processing runs in your browser. Source images are not uploaded by this tool.
Before you start
Your browser must decode images into memory. Very large files, long animations, and large batches may require substantial memory. Check the preview and export details, and verify the latest official requirements before submitting identity, application, or print-ready images.
