Batch behaviour: Multiple files supported

How the browser process works

Cut out the subject and export a transparent PNG using an on-device AI model. The page sends the selected file and settings to its ai-bg-remove browser engine, creates a new output and downloads it without overwriting the source.

The segmentation model (~40 MB) downloads on first use and then runs completely offline in your browser.

Privacy, quality checks and limitations

Keep the original file until the downloaded output has been opened and checked.
Verify page count, orientation, dimensions, text legibility, audio/video duration and metadata relevant to your use.
Browser-local processing reduces routine upload exposure, but your device, browser extensions and download location still matter.
A converted preview is not proof of legal authenticity, archival compliance, accessibility or digital-signature validity.
