Metamorphosec Photo Watermarker is a versatile software that can add watermarks such as text, logos, or QR codes to individual or multiple images. Its Live Preview feature allows users to preview watermarked images. The software is capable of single or batch processing.
When it comes to batch processing, you won't have to worry about losing track of your images because this software also provides you with a list of images. Additionally, you can add copyright and contact information in the metadata. And when it comes to saving your watermarked images, you can choose from JPG, PNG, BMP, GIF, and TIFF.
However, keep in mind that the UNREGISTERED version of the software has limitations. It can only be used for personal use, only allows up to 10 KB, and the Settings feature is disabled. In order to access all of the features the software has to offer, you will need to purchase a License Key.
