How to conceal your information in the image

There are times when you have to conceal the information in your image. You intend to upload a screenshot illustrating your website issue to a forum but don't want people to see the domain of your website. You are writing a tutorial to teach people how to convert Latex to PDF via command lines. You take a screenshot of the CMD window, which shows your admin account you don't want others to see. You want to share a photo online to show off your new car but the photo reveals your license plate number. You are going to post the photo of the express parcel on social media to tell followers you have received the AJ 34. But you find that your address and phone number printed on the parcel are shown in the photo. To conceal the information, you can lean in favor of image editor apps to blur a particular section of the image. In this article, I will walk you through two apps with which you can easily get the job done.

#1. Photo Stitcher

Photo Stitcher is an image editing program developed by Vertexshare. Its name implies that this app is specialized in stitching images together. Photo Stitcher is also able to retouch images to meet different editing requirements.

Open Photo Stitcher and you will be welcomed by a sleek and clean window. The window is mainly divided into two parts. One part is the preview panel, taking up most of the window. In this panel, you can zoom and pan the image, resize the image by changing its height or width, and edit it. The other part is the editing panel, which is on the right side of the window. A collection of tools to touch up the image is distributed in this panel. You can add borders to the image and adjust the size of the borders. You are allowed to add outer borders to the image as well as borders between two adjacent images to be merged. In addition, you can crop the image from side, bottom, and top to remove unnecessary areas. Besides, you can draw free-hand lines, arrows and squares on the image to make annotations. What's more, you can protect your copyright of the image by adding a text watermark or repeated text watermarks to the image. Moreover, you can add a mosaic effect to a particular area of the image to protect your privacy. It is worthy of being mentioned that you are given the ability to customize the colors of border, shape, and watermark.

As a professional image merging software, Photo Stitcher allows you to create a neat collage and make a long and scrolling screenshot. Powered by the advanced panorama algorithm, it also enables you to fuse multiple photos into a wide field of view. You can harness its editing features to edit the image as required. No matter whether you are an inexperienced user or professional, you would find that Photo Stitcher can be easily mastered.

Now, let's dive into the part of how to use Photo Stitcher to hide your information by mosaicking a particular part of the image.
