Creating high-quality collage or replacing the background of a photograph is a task that until recently required professional software on a computer. Today cut out a person you can use a photo directly on your smartphone in a matter of seconds. Owners of Android devices have access to a huge arsenal of tools: from built-in galleries with artificial intelligence to powerful third-party editors.
The process of removing backgrounds has become so simple that even a beginner with no graphic design skills can handle it. Modern algorithms neural networks automatically determine the contours of the figure, hair and clothing, leaving the object clear and natural. You don't have to manually trace every strand of hair or try to carefully cut out your fingers.
In this article, we will take a closer look at how to take advantage of the native capabilities of your smartphone, and also look at the best third-party solutions. You will learn what settings affect the quality of the cut and how to avoid common mistakes when working with object boundaries. Ready to turn ordinary photos into professional images?
Built-in gallery capabilities on smartphones
Many modern smartphones, especially flagship models from Samsung, Xiaomi and Google Pixel, already have the function of automatically cutting out objects directly in the standard gallery. This is the fastest way to get a PNG file with a transparent background without installing additional software. The technology works locally, using the processing power of the device's processor.
To use this option, you usually just need to open a photo in the gallery, click on the object or hold your finger on it. The system will analyze the image and highlight the outline. After this, the “Copy” or “Save as Sticker” button appears. On devices OneUI from Samsung, this function is implemented especially conveniently and allows you to immediately drag the cut-out object into other applications.
If the standard gallery does not cut out the object clearly, try taking a photo in good lighting with a contrasting background - this makes it easier for the algorithms to determine the boundaries.
However, the quality of the built-in tools greatly depends on the processor model and operating version systems. On budget devices or older versions of Android, this feature may be missing or not work correctly, leaving “artifacts” around the edges of the figure. In such cases, you should turn to third-party solutions.
⚠️ Attention: Built-in tools may not cope with complex objects, for example, translucent clothing, thin meshes, or very small details such as individual hairs against a complex texture.
Using online services based on AI
If the phone's capabilities are limited, cloud services come to the rescue. They process the image on powerful servers, which guarantees the highest cutting quality even on weak devices. All you need is a browser and a stable internet connection. Popular services like Remove.bg or Adobe Express cope the task in a few seconds.
The process of use is extremely simple: you go to the site, upload a photo, and the algorithm automatically removes the background. The result can be downloaded in PNG format. The main advantage of such services is that they do not require installation of applications and do not take up space in the smartphone’s memory. In addition, they often update their machine learning models, becoming more accurate every month.
Limitations of free versions
Most online services in free mode provide images in low resolution (for example, 500x500 pixels). High-quality printing or design use often requires the purchase of credits or a subscription.
It is worth considering that when you upload photos to the cloud, your data leaves the device. Although large services claim to be secure and delete files after a short time (usually an hour), it is better to use offline applications for processing sensitive photos. The speed of work also depends on the speed of your Internet connection.
| Service | Cutting quality | Internet required | Free |
|---|---|---|---|
| Remove.bg | Excellent | Yes | Low resolution |
| Adobe Express | Professional | Yes | Yes (with account) |
| Slazzer | Good | Yes | Limited |
| PhotoRoom (Web) | Excellent | Yes | With watermark |
Best applications for cutting out objects
Store Google Play offers dozens of applications specializing in removing the background. Market leaders are considered PhotoRoom, PicsArt i Background Eraser. These apps provide not only automatic removal, but also tools for manual modification, which is critical for complex cases.
The application PhotoRoom is famous for its algorithm, which not only cuts out an object, but also allows you to instantly replace the background with white, color, or any other from the library. PicsArt is also a full-fledged photo editor, with a cutting function (“Cut”) combines with thousands of effects, stickers and drawing tools. For those who want complete control, it's Background Eraser with its Lasso and Magic Wand tools.
- 📸 PhotoRoom: Ideal for product photography and creating stickers, works very quickly.
- 🎨 PicsArt: Best choice for creative collaging and complex effects.
- ✂️ Background Eraser: Provides maximum control over each pixel for manual work.
Most of these applications operate on a Freemium model. Basic features are available for free, but you'll have to pay to remove watermarks, access premium templates, or upload at maximum resolution. Before installing, carefully read the reviews, as some applications may be overloaded with advertising.
Manual correction and working with edges
Even the most advanced artificial intelligence sometimes makes mistakes. After automatic cutting, you may notice that part of the background remains at the edges of the hair or, conversely, part of the object has been removed. This is where the manual correction tools found in advanced apps come in.
Use the Eraser tool with an adjustable brush size to carefully remove any leftover background. To restore accidentally erased parts of an object, use the Heal function or a brush with a plus sign. Pay special attention to the borders: make the edges a little softer (function Feather or “Feather”) so that the object does not look glued to the new background.
☑️ Checklist for high-quality cutting
Working with translucent objects, such as a veil, smoke or glass requires a special approach. In such cases, automation often makes the object completely opaque or removes it altogether. The layer blending mode and manually drawing a transparency mask will help here, although this requires certain skills and patience.
⚠️ Attention: When manually refining, always increase the image scale to the maximum. On a small screen, errors may not be noticeable, but when viewed on a computer or printed, they will become obvious.
Replacing the background and creating collages
Once the person has been successfully cut out, it's time to place him in a new environment. Most applications allow you to add a new layer with a background image. It is important to monitor lighting and perspective: if the subject was shot with the bright sun on the left, and the new background depicts a cloudy evening, the picture will look unnatural.
Use color correction tools to create a harmonious collage. Adjust the temperature, brightness and contrast of the cut-out object so that they match the parameters of the new background. It is also useful to add a light shadow under the object to “anchor” it to the surface and avoid the effect of levitation.
Modern applications often offer ready-made scenes for collages. You can place the cut out photo in a frame, add text or decorative elements. Always save the final result in the format PNGif you plan to use the image further, since the format JPEG does not support transparency and will fill the background with white.
The PNG format is the standard for images with a transparent background. Saving in JPEG will destroy the transparency and replace it with white or black.
Common problems and solutions
Users often encounter the fact that after cutting, a colored border (usually white or black) remains around the object. This occurs because the background pixels are mixed with the subject pixels when the photo is taken. You can solve this problem using the “Defringe” function in the application settings, selecting the color that you want to remove.
Another common problem is “soapy” hair edges. This happens when the original photo has a low resolution or aggressive compression. Try using the original file at its highest quality and apply the sharpening tool specifically to the outlines of the object after cutting. Do not sharpen the entire image so as not to increase noise in the background.
- 🚫 Low resolution: Always start working with the original photo, and not with a small copy from instant messengers.
- 🌫️ Color fringing: Use the border removal tool or manually go over the contour with an eraser.
- 🔍 Loss of detail: When working with small objects, increase the zoom and use a minimum brush size.
If the application constantly crashes when processing a heavy photo, try closing other running apps and freeing up RAM. Processing high-resolution images requires significant device resources.
Is it possible to cut out a person on an old Android?
Yes, you can. Older versions of Android may not have built-in gallery features, but you can always install lightweight apps from Google Play or use your browser to access online services. The main thing is that the device supports modern web page standards.
Which format is best for saving a cut out photo?
The only correct format for saving an image with a transparent background is PNG. JPEG and WEBP formats (in some cases) do not support alpha channel (transparency) and will replace empty areas with a solid color.
Why does cut-out hair look unnatural?
This is a common problem with algorithms. Fine hair is often perceived as a background. Try using applications marked AI Hair Masking or manually refine the edges with the “Restore” tool, carefully drawing the strands.
Do you need the Internet for applications to work?
Not always. Built-in galleries and many features of apps like PicsArt work offline, using the phone's processor. However, services based on cloud AI (for example, Remove.bg) require a network connection for processing.
