How to Scan a Document on Xiaomi: The Complete Guide

In the digital age, the need to carry paper documents is gradually disappearing, giving way to electronic copies. Smartphones brand Xiaomi, Redmi and Poco are equipped with powerful cameras and software algorithms that allow you to turn a regular picture into a quality one. PDF-You no longer have to look for a scanner or a computer to handle an important reference, contract or lecture summary.

MIUI and its newer version of HyperOS offer native tools that are often underrated by users. The standard Camera or Scanner app can automatically define the boundaries of a document, level perspective, and improve text readability by removing shadows and highlights, making the digitization process not just fast but also professional.

In this article, we will take a closer look at all the ways you can create digital copies on your devices, and we will look at the built-in features, the capabilities of the Google ecosystem, and specialized applications that will help you always have neatly designed files at hand.

Use of the built-in Scanner application

The most obvious and often ignored tool is the system app, which is preinstalled on every Xiaomi device, which is simply called the Scanner, and has an icon with a square or barcode image. QR-codes, but has a powerful mode of working with documents.

When you start the application, you need to switch to Documents mode. The camera will automatically try to find the edges of the sheet against a contrasting background. For best results, place a white sheet on the dark surface of the table so that the algorithm clearly sees the boundaries. After pressing the shutter button, the image is instantly processed: it is cropped, straightened and translated into black and white to save space and improve readability.

⚠️ Note: Do not use Photo mode to scan text if you need a document. In Photo mode, the camera saves all shadows, paper irregularities and color distortions, which makes the text less readable on the screen.

The built-in scanner features a way to save the result as a PDF or a gallery image. You can scan multiple pages in a row, forming a single file, which is extremely convenient for multi-page contracts. Once you've finished shooting, the system will suggest sending the file via messengers or saving it to the cloud.

Use the Improve mode in the built-in scanner to automatically remove the yellow tint from the old paper and make the text more contrasting.

Scanner of documents through the Camera application

Many users don't know that a separate Scanner app is not available on the menu, because it's built right into the standard Camera, which is especially useful when you need to quickly capture information without unnecessary clicks on the menu. MIUI HyperOS and the functionality is integrated as deeply as possible.

To activate scan mode, open the Camera app and find Documents in the bottom menu or mode drop-down. In some models, it may be called More β†’ Documents. The camera will go to a special mode where the interface will tell you that the object is recognized as text or document.

The main advantage of using the main camera is access to higher resolution settings and image processing algorithms, which may differ from those used in the Scanner application.

  • πŸ“Έ Automatic recognition of the edges of the document occurs in real time.
  • πŸ“„ Packet scanning capability: take a photo of the first page, then the second, and the system will combine them.
  • 🎨 Processing Filters: Choosing between a color, black and white mode or a "board" mode to improve contrast.

Once you have created a picture, you can immediately edit it: rotate, crop it again or apply a filter. The finished file is saved in a separate Scanner or Documents folder inside the gallery, making it easier to find the desired files among personal photos.

Google Lens and Google Drive for Digitization

If standard Xiaomi tools for some reason do not suit you, come to the rescue services from Google, which are preinstalled on all certified smartphones. Google Lens is a powerful computer vision tool that can not only recognize objects, but also scan text.

You can run Google Lens through a widget on your desktop, through the Google app, or directly from the camera interface if it's activated. Select Text or Document mode. After you shoot, the system will suggest saving the image, copying the text, or sending it to other applications. This is ideal if you need to not just save the picture, but to extract text information.

Another powerful tool is the Google Drive app, which has a hidden scan feature Β«+Β» (add) in the lower right corner and select "Scan" and the camera will open, which will take the picture, process it and immediately save it as a picture. PDF-File directly into your cloud storage.

The advantage of using the Google ecosystem is synchronization, which means that if you scan a document on a Xiaomi phone, you can instantly access it from any other device that you log in to, eliminating the risk of data loss when your smartphone breaks down.

⚠️ Note: Google Lens and Google Drive Requires an Active Internet Connection to Work; Without a Network, Functionality Can Be Limited to Basic Recognition.

Third-party applications for professionals

For users who need advanced features such as save formatting text recognition (OCR), PDF editing, or cloud synchronization with enterprise servers, there are specialized applications that often do complex tasks better than standard tools.

One of the most popular solutions is Adobe Scan. This free app automatically finds the edges of a document, removes glare and creates clearer ones. PDF-It can also recognize text by turning a picture into an editable document. Another market leader is Microsoft Lens, which integrates well with Word and OneNote office suites.

Installing third-party software makes sense if you work with documents daily, but it’s worth remembering that such applications often require more permissions to access data and may contain advertising in free versions. Xiaomi’s standard tools are faster in most household cases and do not require additional software installation.

Why can third-party apps run slower?
Third-party applications often use native image processing algorithms that require more CPU processing power and RAM than optimized MIUI system utilities.

Processing and editing of scanned files

Once the document is scanned, it often needs to be refined. Xiaomi's built-in galleries and scanning apps offer a basic set of tools. You can cut the extra edges if the automation is wrong, or rotate the image 90 degrees.

The important step is to improve the quality. If the original image is dark or pale, use filters. Black and white or Increase contrast makes the text as clear as possible, sacrificing color illustrations if any. For color graphs and diagrams, you should choose the Original or Magic of Color mode.

If you use third-party apps like Adobe Scan or TurboScan, you can combine multiple snapshots into one. PDF-And then you can change the order of the pages and add watermarks, and that turns your smartphone into a full-fledged office scanner.

  • βœ‚οΈ Cutting: Manual adjustment of document boundaries.
  • 🎨 Filters: the choice between color, ch/b, gray and board mode.
  • πŸ”€ OCR: copying.

Remember to check the result before sending. zoom in and make sure all numbers and letters are readable clearly. Unreadable scans can lead to errors in filling out forms or financial losses.

Preservation and transfer of documents

The final step is saving and transferring a file. Today's Xiaomi smartphones allow you to do this in a variety of ways. The fastest is through messengers. After scanning, click the "Share" button and select Telegram, Viber or WhatsApp.

For official correspondence it is better to use the format PDF, Because it ensures that the document opens the same way on any device and that its contents are not accidentally altered. JPG Suitable for fast demonstration, but can lose quality when compressed by messengers.

Cloud storage remains the most reliable way to archive: set up automatic sync of the Scanner folder with Google Photos or Mi Cloud, in which case, even if you lose your phone, all your important documents will remain safe in the cloud.

⚠️ Note: When transferring documents via instant messengers, always choose the option β€œSend as a file” or β€œDocument” to avoid heavy compression of the image, which will make small letters unreadable.

Use a file manager to sort. Create separate folders for different types of documents: taxes, jobs, studies, which will save you hours of searching in the future when you need to find a specific help urgently.

Automatic synchronization of the scan folder with the cloud is the only guarantee that important documents will not be lost when a smartphone breaks down or is stolen.

Can I scan documents without the Internet on Xiaomi?
Yes, the built-in Scanner app and the Documents mode in the camera are completely offline. The image processing is done on the phone's processor. The Internet is only needed to send the file or save it to the cloud.
Which format is better to save scans: JPG or PDF?
For text documents, contracts and references, always choose PDF. This format captures the layout and scales without loss of quality. JPG only for color images, where detail is important, not text.
Why does the scan turn out to be curved or skewed?
This happens if the camera can't automatically define the boundaries of the sheet, try putting the document on a contrasting background (a dark white paper table) and hold the phone parallel to the sheet, and you can also cut the edges manually in the editor.
How to scan a document in high resolution?
Use a high-resolution main camera (48MP, 64MP and higher) and avoid digital zoom. Make sure you select the best photo quality in your camera settings. Third-party apps like Adobe Scan also allow you to choose the quality of your save.
