Processing photos directly on a smartphone has long ceased to be the lot of professionals with cumbersome software. Today, you can remove an unnecessary object in the background or replace it with an abstract blur in a couple of clicks. Users of Android devices are often faced with the need to hide distracting details in order to focus on the main subject.
There are many methods, from simple built-in editors to powerful neural networks. In this article, we will look in detail at how to effectively cover up the background using various tools at your disposal.
Built-in capabilities of Google Photos and manufacturers' editors
First of all, you should pay attention to the basic software that is already pre-installed on your device. The application Google Photos for Google One subscribers is available with the “Magic Eraser” function. This tool uses machine learning algorithms to automatically remove objects.
To use this option, open a photo, click the button Edit and select the tools tab. Find the eraser icon and activate the mode Erasing objects. Just swipe your finger over the area you want to hide, and the system itself will fill the space with environmental pixels.
⚠️ Attention: The Magic Eraser function is fully available only with a Google One subscription. Without a subscription, the number of free saves per month may be limited by the developer.
Smartphone manufacturers such as Samsung and Xiaomiare also introducing their own solutions. Samsung Gallery has an Object Eraser tool that works on a similar principle. It often does a better job than third-party applications due to its deep integration with the phone's hardware.
If automatic removal does not give an ideal result, try using the function Blurring the background. It does not completely remove the object, but makes it indistinguishable, which often looks more natural than low-quality retouching.
For the best performance of the algorithms, try to select the object with a small margin, capturing a couple of pixels of the background around it.
Using specialized applications for retouching
When the built-in tools are not enough, third-party apps from Google Playcome to the rescue. The leaders in this niche are Snapseed, PicsArt i TouchRetouch. Each of them has a unique approach to image processing.
The application Snapseed from Google uses the Spot tool. It's ideal for removing minor imperfections or small objects in the background. The principle of operation is simple: you touch the screen in the place that needs to be corrected, and the algorithm replaces this area with the texture of nearby pixels.
More complex tasks, such as removing large people or buildings, are better solved in TouchRetouch. This paid application specializes specifically in frame cleaning. It allows you to delete objects by contour, lasso, or even remove power lines with one touch.
- 📸 Snapseed: A free, powerful tool with professional curves and spot correction.
- 🎨 PicsArt: A creative combine that allows you not only to remove, but also to replace the background with other images.
- 🧹 TouchRetouch: A highly specialized solution for perfectly clearing the frame of debris.
It is important to understand the difference between removing an object and replacing the background. If your goal is to completely change the location of a person, you will need functions for working with layers, which are available in PicsArt or PhotoRoom.
Working with blur and Bokeh effect
Sometimes the task is not to remove an object, but to create an artistic blur that imitates the work of expensive optics. This effect is called Bokeh. On Android, you can add it both during shooting and after.
Many modern smartphones have a “Portrait” mode, which automatically blurs the background. However, if the photo has already been taken in normal mode, it is more difficult to change the depth of field after the fact. Apps like AfterFocus allow you to manually select the focus area.
The process goes like this: you outline the object that you want to remain sharp, while the rest of the image becomes blurry. The intensity of the effect can be adjusted with the slider. This is a great way to save a shot taken against a chaotic background.
⚠️ Attention: When manually selecting the boundaries of an object, be extremely careful. Uneven edges can reveal the artificiality of the processing and ruin the impression of the photo.
Some editors offer ready-made blur filters: Gaussian, radial or motion blur. The choice of a specific type depends on the artistic task. For portraits, radial or imitation optics are better suited.
The Bokeh effect helps to visually separate the object from the background, even if it is impossible to physically remove the background without loss of quality.
The use of neural networks and online services
Artificial intelligence technologies have revolutionized mobile photography. Neural networks are capable of analyzing a scene and understanding where the person is and where the background is with high accuracy. This allows you to remove the background completely, making it transparent.
Services like Remove.bg or built-in functions in new versions of Android (starting from version 12 in some implementations) do this in seconds. You do not need to select anything manually - the algorithm finds the contours itself.
After removing the background, you can substitute any other color, gradient or photo. This opens up enormous possibilities for creating stickers, avatars or collages. The quality of cropping in modern AI often exceeds manual work in Photoshop on a computer.
| Service / Application | Type of processing | Cost | Edge quality |
|---|---|---|---|
| Remove.bg | Online / API | Freemium | High |
| PhotoRoom | App | Subscription | Very high |
| Adobe Express | Online / App | Free | Average |
| Built-in AI Android | System | Free | Depends on the model |
It is worth considering that processing in the cloud requires a stable Internet connection. If you are in an area of poor reception, it is better to use offline applications with pre-installed AI models.
Fine-tuning and edge correction
Even the best algorithms sometimes make mistakes, leaving “halos” or cutting off parts of the object. At this stage, manual revision comes into play. In the same Snapseed or PicsArt there are tools for point correction of the mask.
Use the recovery brush to restore accidentally deleted parts of clothing or hair. Conversely, use a burn or clone brush to remove any background residue that is stuck to the subject.
Pay special attention to hair and translucent objects. These are the most difficult elements to automatically select. A combination of tools often helps here: first, automatic removal, then manually completing the background by cloning.
The secret of working with hair
Do not try to perfectly highlight every hair. It's better to leave a slight translucency around the edges than to end up with a hard, unnatural border that looks like a cut-out sticker.
It is also useful to use the sharpening tools (Sharpening) on the edges of the object after processing. This will help visually separate it from the new background and hide minor anti-aliasing artifacts.
Saving the result and file formats
After completing all manipulations, it is critically important to save the file correctly. If you have removed the background and want to use the image in other projects, be sure to select Format PNG.
Format JPEG does not support transparency and will fill the empty areas with white or black, destroying all your work in removing the background. PNG preserves the alpha channel, providing transparency.
When saving, pay attention to the compression quality. Compression that is too aggressive can result in "squares" and noise in uniform areas of the background, especially if you have used blur.
⚠️ Attention: Some Android galleries may not display transparency correctly in PNGs, showing a checkerboard background. This is normal; when sending the file to instant messengers, transparency will remain.
To archive source files, it is recommended to save a copy in maximum quality without compression, in order to be able to return to editing in the future. Data loss when saving again in JPEG is irreversible.
☑️ Final check before saving
Is it possible to remove the background on a video on Android?
Yes, it is possible, but it requires more powerful applications such as CapCut or KineMaster. The process is called "chromakey" or the use of AI masks for videos. It is much more complex and resource-intensive than working with photos.
Which application is best for beginners?
For starting, Google Photos (if you have a subscription) or Snapseedis ideal. They have an intuitive interface and are free. PhotoRoom Also very easy to quickly change the background.
Why do white spots appear after removing the background?
Most likely, you saved the file in JPEG format, which does not support transparency. Or the algorithm could not correctly process complex boundaries, and you need to modify them manually with the Clone tool.
Do you need a powerful phone to work with neural networks?
For cloud services (online), the power of the phone is not important, the main thing is the Internet. For local processing of heavy applications, a mid-level processor and at least 4 GB of RAM are desirable.
