To instantly remove the background from any image on iOS, you can use third-party image editing apps available on the App Store. One such app is "Remove.bg" [note: link not available], which allows you to easily remove the background from your images. Here's how to use it:

  1. Download and install the "Remove.bg" app from the App Store.
  2. Launch the app and either take a new photo or open an existing image from your gallery.
  3. The app will automatically detect and remove the background from the image.

If the app doesn't work perfectly, you can try other third-party image editing apps from the App Store. Some popular options include PicsArt, Adobe Lightroom, and Canva. These apps offer various photo editing tools, including background removal features. Simply upload your image to the app, select the background removal tool, and follow the app's instructions to remove the background from your image.
