Frequently Asked Questions
Everything you need to know about processing files securely in your browser
How does the offline background removal tool work?
This tool runs an AI segmentation model directly in your web browser. All image processing and calculations are performed locally on your device, ensuring your photo never leaves your computer.
Is my image uploaded to any server for background removal?
No. Unlike other background removal services, we process 100% of the data locally inside your web browser. No servers receive, view, or store your images, making this completely private and secure.
Can I save the result as a transparent PNG?
Yes! Once the background is removed, the cut-out image is automatically generated as a PNG with transparent transparency, keeping your subject isolated.
Is there a limit on the number of images I can process?
There are absolutely no usage limits, paywalls, or registrations. You can remove backgrounds from as many images as you need.
