Smeared text on a screenshot is a common problem faced by users of Androiddevices. Most often this happens when trying to hide confidential information: passwords, card numbers, personal messages. But what if you necessary restore this text? Is this technically possible?

The answer depends on covering method. If the text is hidden by a simple black rectangle (without blurring or pixelation), the chances of recovery are higher. If tools like Blurring or Pixelationwere used, the process becomes more complicated. In this article we will examine 7 proven methods —from manual editors to neural networks—that will help reveal hidden information. It is important to understand: There is no 100% guarantee, but a competent approach increases the likelihood of success.

Also consider legal and ethical aspects. Restoring blurred text without the owner's consent may violate privacy laws (for example, FZ-152 "On Personal Data" in Russia). Use these methods only for personal purposes —for example, to remember your own password on an old screenshot.

1. Checking the source file: are there layers or editing history?

Before proceeding with complex manipulations, check whether the original version of the screenshot has been saved. Many editing applications (for example Adobe Photoshop Express or PicsArt) create copies of files with the extension .psd, .xcf or save the history of changes in the cloud.

Where search:

  • 📁 Folder DCIM/Screenshots — sometimes the originals remain here even after editing.
  • 🔄 Trash (if you used Google Photos or the standard application Gallery).
  • ☁️ Cloud services: check Google Drive, Dropbox or OneDrive for backups.
  • 🖥️ PC: if the screenshot was transferred to the computer, look for temporary files in %Temp% (Windows) or /tmp (macOS/Linux).

If the screenshot was edited in Photoshop or GIMP, try opening it in these apps - sometimes layers are saved even after exporting to .jpg or .png. To do this:

  1. Copy the file to your PC.
  2. Open in Photoshop via File → Open as... and select format PSD.
  3. Check the panel Layers (F7) - if the putty was on a separate layer, it can be deleted.
⚠️ Attention: If the screenshot was taken through Power + Volume Down and immediately edited in Google Photos, the original could be automatically deleted after saving the changes. In this case, you can only restore it through backup copies.

2. Increasing contrast and brightness: a simple method for black putties

If the text is painted over solid black rectangletry increase contrast i lower brightness. This method works because putty pixels are often solid black ( minor differences from pure black (#000000), especially if editing was done in mobile apps.

Instructions for Android (using Google Photos):

  1. Open the screenshot in Google Photos.
  2. Click Edit → Tools → Settings.
  3. Move the sliders:
    • Contrast: +80–100%
    • Brightness: -30–50%
    • Shadows: +40–60%
  • Save a copy and check the result.

    • For more precise adjustments, use Snapseed (free application from Google):

    1. Open the image in Snapseed.
    2. Select Tools → Curves.
    3. Raise the curve in the dark tones area (lower left corner of the graph).
    4. Apply changes and export the file.
    Application Max. effect Complexity Suitable for
    Google Photos Weak ⭐ Shallow putties
    Snapseed Average ⭐⭐ Black rectangles
    Lightroom Mobile High ⭐⭐⭐ Complicated cases
    Photoshop Express Average ⭐⭐ Colored putties
    💡

    If the putty is not pure black, but dark gray, try inverting the colors (Tools → Color → Invert in Snapseed). Sometimes this reveals hidden symbols.

    3. Using the Histogram and Levels in Photoshop (for PC)

    If you have access to a computer Adobe Photoshop offers the most powerful tools for working with blurred areas. The method is based on the analysis of histogram - a graph of the distribution of pixels by brightness.

    Step-by-step guide:

    1. Open the screenshot in Photoshop.
    2. Go to Window → Histogram (Ctrl+Alt+0).
    3. If there are peaks in the area of dark tones (on the left), this means that the putty is not perfectly black.
    4. Open Image → Correction → Levels (Ctrl+L).
    5. Move black slider to the right until the beginning of the peak (usually the value 10–30).
    6. Increase middle slider (gamma) to 0.7–0.9.
    7. Apply changes and save a copy.

    If the putty is colored (for example, blue or red), use channel correction:

    1. In the window Levels select channel (RGB, Red, Green, Blue).
    2. Adjust each channel separately, observing changes in the putty area.
    3. For blue putty, reduce the tab Blue channel, for red - Red.

      4. Zoom up to 200-300%|Check the histogram for peaks|Save the original in a separate folder|Use the "Levels" or "Curves" correction-->

      Critical point: if the histogram shows a straight line in the black area (value 0), then the putty is perfect, and restore the text using this method impossible.

      4. Recovery algorithms: online services and neural networks

      If manual methods do not help, contact specialized online services and neural networks, trained to recover hidden information. compression artifacts, residual data and patterns pixels.

      Top 5 restoration services:

      • 🤖 Remini —uses AI to improve blurred areas. Suitable for pixelation.
      • 🔍 Let’s Enhance —increases resolution and reveals hidden details.
      • 🖼️ Depixelize —specializes in pixel putty.
      • 📊 FotoForensics — analyzes JPEG compression errors (method Error Level Analysis).
      • 🛠️ Adobe Photoshop Online — web version with tool Generative Fill (artificial intelligence).

    How to use FotoForensics (for the technically savvy):

    1. Go to the website and upload a screenshot.
    2. Select Error Level Analysis (ELA).
    3. Analyze the result: bright areas indicate editing. If the putty stands out, you can try to remove it.
    4. Download the processed image and modify it in Photoshop.
    ⚠️ Attention: Online services can save downloaded images on their servers. If the screenshot contains confidential data, use offline solutions (for example, GIMP with a plugin Resynthesizer).
    How Error Level Analysis works (ELA)?

    ELA shows the levels of JPEG compression errors. When editing an image (for example, adding a black rectangle), these errors change. The service highlights areas with inconsistencies, which helps to identify manipulations. The method is effective for JPEG, but useless for PNG or RAW.

    5. for experienced users

    This method is suitable if the screenshot is saved in the format JPEG and the putty was applied on top of the original layer without resaving. In this case, the HEX code of the file may remain source text fragments.

    Instructions (PC required):

    1. Copy the screenshot to your computer.
    2. Install a HEX editor (for example, HxD or 010 Editor).
    3. Open the file in the editor.
    4. Find the beginning of the blurred area (guide by the X/Y coordinates in Photoshop).
    5. View the HEX code for the presence readable characters (for example, 48 65 6C 6C 6F = "Hello").
    6. If you find fragments, copy them and decode them via HEX-to-ASCII converter.

    Method limitations:

    • ❌ Does not work for PNG (lossless compression does not leave artifacts).
    • ❌ If the image was resaved after blurring, the data is overwritten.
    • ❌ Requires knowledge of HEX encoding and JPEG structure.

    Alternative: use the utility Binwalk (Linux/macOS) to parse the file: 

    binwalk -e screenshot.jpg

    It will extract all embedded data, including possible metadata with the original text.

    💡

    HEX editing is the riskiest method. An error in one byte can completely ruin a file. Always work with a copy!

    6. Metadata analysis: EXIF ​​and hidden tags

    Sometimes text not blurred, but hidden in file metadata. For example, if a screenshot was taken through ADB or specialized applications (like Screen Master), in EXIF the following may be saved:

    • 📝 Original text (if the screenshot was created via OCR).
    • 🖥️ Device information (model, Android version).
    • 📅 Date and time (helps to find the original in backup copies).

    How to view metadata:

    1. Install EXIF Viewer from Google Play.
    2. Open the screenshot in the application.
    3. Check the fields:
      • Software - the app that was used to make screenshot.
      • UserComment —sometimes text is saved here.
      • XMP —extended metadata (may contain OCRrecognized text).

    For PC use ExifTool (command line): 

    exiftool -a -u -g1 screenshot.jpg
    ⚠️ Attention: Metadata is often cleared when editing on social networks (WhatsApp, Telegram) or cloud services. Check the original file, not the downloaded copy.

    7. Alternative methods: from OCR to social engineering

    If technical methods do not work, consider non-technical approaches:

    1. OCR recognition of partial text

    If the text is not completely blurred, use Google Lens or Adobe Scan to recognize visible fragments. The algorithm can restore the logic (for example, recognize the card number by the first digits).

    2. Contextual analysis

    Try to remember what was in the screenshot:

    • 💳 If these are bank details, check the transaction history in the mobile bank.
    • 🔑 If the password, look at the saved data in Settings → Google → Account management → Security → Passwords.
    • 📧 If it’s a letter, find it in Gmail by date (it is visible in the screenshot file name).

    3. Social engineering (extreme case)

    If the screenshot was sent by another person, you can politely ask send the original under the pretext:

    • "I can’t understand the font, can you clarify?"
    • "You need to confirm the data, please send without putty."

    ⚠️ This method risky can violate trust.

    💡

    The less time has passed since the screenshot was taken, the higher chances to recover the text. Backups, application caches and cloud services store data for a limited time.

    FAQ: Frequently asked questions about restoring blurred text

    Is it possible to recover text if a screenshot is blurred in WhatsApp?

    WhatsApp compresses images when sent, which complicates recovery. However, if the putty is applied on top of the original (without over-preservation), try methods with increasing contrast or FotoForensics. The chances are low, but they exist.

    Will a neural network help if the text is covered with a colored rectangle?

    Yes, but the effectiveness depends on the color. Remini or Let’s Enhance work better with blurthan with uniform colors. For color putties, first convert the image to Black and white mode in Photoshop, then apply AI.

    Is it possible to restore text to screenshot taken 5 years ago?

    Technically possible if:

    • The file was not oversaved.
    • There are backups on Google Disk or in the cloud.
    • The format was used PNG (fewer compression artifacts).

    Start by searching for the original in archives or metadata.

    Is it legal to restore smeared text on someone else's screenshot?

    No. In Russia, this may be qualified as violation of Art. 137 of the Criminal Code of the Russian Federation ("Violation of privacy") or art. 272 of the Criminal Code of the Russian Federation ("Illegal access to computer information"). Use methods only for personal data.

    Which Android application is best suited for recovery?

    For mobile devices we recommend:

    • Snapseed — for manual correction.
    • PicsArt — for working with layers (if the original is multi-layered).
    • PhotoRoom — for AI restoration (paid).

    For serious tasks it is better to use a PC and Photoshop.
