Say goodbye to the cumbersome background removal! Four free applications can easily solve the picture background

Want to make a beautiful emoji or Slack emoji? Simple screenshots can no longer meet the needs. At this time, you need a tool that can efficiently remove the background of the picture.

In the past, removing the background of the picture required proficient PS skills. Now, the latest iOS system and some image editing tools can help you easily and for free without any professional skills.

"Copy Subject" function of iOS 16

Blessed iPhone users! If you upgrade to the latest iOS system, the "Copy Subject" function can directly help you extract subjects from images and remove backgrounds.

How to use it is as easy as copying and pasting text. Open the photo, press and hold the image body, and select Copy (or select Copy subject when copying the image from the web page) or Share. Once copied, you can paste the extracted subject anywhere, such as chat groups, memos, and social media. If you select the File app, the body will be automatically saved as a PNG file with a transparent background.

The accuracy of this function depends on the subject's contrast to the background and the clarity of the subject's profile. For example, for brides photographed in the snow, AI may have difficulty distinguishing wedding dresses from snow; clear Pett contours are easier to extract than furry German Shepherds.

Although the "Copy Subject" function is convenient and fast, its accuracy still needs to be improved, especially in scenarios with low contrast. However, it is definitely the best choice for quick emoji production.

Picsart

Picsart's web version provides free background removal tools that automatically identify and remove image backgrounds using AI.

Visit Picsart's Quicktools website, click "Select File", upload the picture, and the platform will automatically remove the background immediately.

Picsart's background removal function is quite accurate, but if there are still imperfections, you can use the manual editing tool to fine-tune it. Click the eraser icon in the upper left corner of the picture preview to erase the excess with the brush; if too much erase, you can use the "Recover" function. The Size slider controls the brush size, and the Hardness slider controls the erase strength. There are also zoom-in (up to 300%) and undo/redo functions at the bottom.

After finishing, click "Apply", select the appropriate size, or click "Download" to save to your computer.

Although the web version is free, the full functionality of the mobile app requires a Picsart Gold subscription ($4.66 per month). The mobile app version can only use the automatic background removal function and cannot be manually edited.

How to use mobile app: Open the App, log in, click the " " at the bottom, select the picture, and click the "Remove BG" button at the bottom to automatically remove the background. The biggest advantage of the App version is that it can customize the replacement background, you can choose solid colors, gradient colors, or select pictures from the material library.

The manual editing method is the same as the web version, but the mobile phone screen is smaller and may not be convenient to operate. It lacks rotation and angle adjustment functions, and can only rely on zoom gestures, which are easy to operate incorrectly.

After finishing, click the check mark in the upper right corner to save the changes, and then click the arrow icon to continue. Picsart will prompt you to publish your work, click "Skip" and "Save" to save the picture to your mobile album.

Picsart will not add watermarks.

Remove.bg

As the name suggests, Remove.bg focuses on removing the background of the image. It is simple and easy to use and free. Upload or drag and drop the picture and the platform can automatically remove the background.

Remove.bg's accuracy is surprising, and even furry hair or fluttering clothing can be easily identified. If you are satisfied with the results, click "Download" or "Download HD version" (HD version charges). If you are not satisfied, click the "Edit" button in the upper right corner to adjust manually.

The manual editing tool is similar to Picsart, but the function is more simplified. Only the "Size" slider controls the size of the brush, there is no undo button, and you can only use the "Recover" function to restore the accidentally deleted part. There is a zoom option at the top.

When finished, click "Download" (or "Download HD") to save as a PNG file. Remove.bg also does not add watermarks.

Adobe Express

Adobe also offers free background removal tools without an Adobe subscription. It is easy to use and powered by Adobe's AI, with the effect comparable to Photoshop.

Visit the Adobe Express background removal page and click "Upload Photos" to upload the picture. The platform is powerful, but if you only need to quickly remove the background, this shortcut is enough.

Adobe Express will automatically remove the background and the effect is accurate. If you are satisfied, click "Download" to save. If you are not satisfied, click "Custom" to use all the features of Adobe Express.

To perform manual editing, you need to create or log in to an Adobe account. Click on the body and then click "Edit Crop". You can use a tool like Remove.bg to adjust the outline, you can adjust the brush size, switch the "Erase" and "Recover" modes, but you cannot adjust the hardness or opacity. In addition, there is a "Inverted Clipping" feature that preserves the background and removes the subject.

When finished, click the check mark in the upper right corner. You can continue to add text, filters, strokes and other pictures. After being satisfied, click "Download" in the upper right corner and select "PNG (Transparent Background)" format to save.
