How to Use

  1. Upload your photo (JPG or PNG — up to 50MB per file) that has a distinct foreground subject.
  2. Click 'Remove Background'. The first execution downloads a ~30MB AI model locally, which then caches for instant subsequent runs.
  3. Wait for the on-device AI model (@imgly/background-removal) to process the image inside your browser sandbox.
  4. Review the transparent preview and download the output as a transparent PNG file.
  5. Perfect for creating e-commerce product listings, profile photos, custom avatars, or marketing collateral.
  6. All processes are GPU-accelerated and run locally, ensuring your private photos never reach an external server.

All processing is done in your browser, and files are never sent to a server.

The browser needs to download the ~30MB AI model parameters into its cache. Once downloaded, subsequent runs load instantly in a fraction of a second.
It excels at subjects with clear borders (people, products, vehicles). For complex scenes, fuzzy hair, or low-contrast borders, some edge refining or manual touch-up may be required.
Yes. The tool automatically removes background pixels and exports the result as a PNG with an alpha transparency channel.

To prevent browser memory depletion, the tool processes one image at a time. Please wait for the current image to complete before uploading another.
The AI model performs best at typical web resolutions. Extremely large megapixel images will be downscaled slightly during processing to maintain browser stability.
