Introduction

 

Snagit provides a number of ways to redact, delete, or edit sensitive information in an image. For example:

  • Redact confidential information, such as credit card and social security numbers.
  • Blur sensitive or distracting information, such as license plates or employee profile pictures.
  • Remove or edit personal information, such as names or contact information.

Option 1: Automatically Redact Sensitive Information

 

Smart Redact identifies and automatically covers sensitive information, such as contact information, credit card numbers, and more.

Before and after example of Smart Redact

To automatically redact sensitive information in an image:

  1. Click the Blur tool in the Snagit Editor toolbar, or from the More dropdown in the toolbar.
    Blur tool
  2. In the Actions panel, click Smart Redact.
    Smart Redact button
    Snagit detects different categories of sensitive information and covers them with black shapes.
  3. Complete any of the following to edit the redactions:
    • Toggle off information categories that you want to keep visible in the image. Snagit removes redactions from those categories.

    • In the Type dropdown, select the Blur or Pixelate option to change the appearance of the redactions.

      Note: Some third-party tools can reverse blur or pixelation. For the most secure option, keep the Black shapes redaction type.

  4. Click Done to close Smart Redact.
  5. To edit individual redactions or blurs, complete any of the following:
    • To remove a redaction and reveal the information underneath, click to select the redaction and press Delete.
    • To edit the redaction type, shape, or intensity (blur and pixelate types only), click to select the item, then adjust the tool properties.
  6. Flatten the image before sharing so that redactions and blurs cannot be removed to reveal the information underneath. Complete any of the following:
    • Right-click the image and select the Flatten All option.

      Note: With this option, redactions and blurs cannot be edited further.

    • Click Share Link to share the image via Screencast. See Get a Shareable Link.
    • Select File > Save As and save the image in a flattened format such as JPEG, PNG, GIF, or PDF for sharing.

Note: Smart Redact leverages AI technology, specifically ABBYY and OpenCV Classifier on Windows and Apple OCR and Apple Person Selection on Mac, to identify common patterns of sensitive information in text and images. Neither the image nor the sensitive information in the image is uploaded to TechSmith or to any service provider, so your data remains secure. For more information, see TechSmith and AI.

Option 2: Blur Individual Items

 

Blur or pixelate part of an image, such as a profile picture or license plate, to quickly hide identifiable details.

Note: Smart Move leverages OpenCV AI technology to identify editable objects in an image. This runs locally in Snagit on your computer.
