To remove the background of a picture, the process typically involves three simple steps:

1. Upload the image file (often JPG, PNG, or HEIC) to an online background remover tool or a photo editing software with background removal features.
2. The tool or software automatically detects and removes the background area, leaving the main subject isolated.
3. Download the resulting image with a transparent background, or add a new background color or image if desired.

Several online tools make this quick and easy using AI technology, such as Pixelcut, Adobe Express, Remove.bg, and others. These tools often work in seconds without requiring manual editing, and you can refine the edges if needed. Some tools also offer apps for mobile devices to remove backgrounds directly from phone photos. For example, Pixelcut's background remover instantly removes backgrounds automatically in less than 3 seconds and allows downloading the image with a transparent background or adding a new one. Adobe Express also offers a free, no-sign-up-needed background removal that works well by uploading an image and automatically erasing the background. Additionally, Microsoft Office has a background removal option for pictures inserted in Office documents, where you can manually mark areas to keep or remove if the automatic detection needs adjustment. Overall, the best approach depends on the user's needs and the software or tool available, but online AI- powered background removers provide a fast and simple solution for most users. This summarized method applies to many current popular tools and software as of 2025.
