UMark

UMark is intended to stamp watermarks on batches of pictures. The tool has a straightforward interface; which is, unfortunately, rather plain as well.

It supports importing not only individual files but also complete folders. Luckily, such popular formats as BMP, GIF, JPG, PNG, and TIFF are supported.

Good news is that you can add various types of watermarks, including text, images, shapes and QR code. These objects have modifiable properties, like rotation angle and transparency degree. Likewise, you can use the preset positions or insert an exact custom position. Not only that, the watermarks can also be easily dragged to the desired place. The program also supports adding frames to the pictures.

A very convenient feature of UMark is that it lets you use macros to create automatic text watermarks. Thus, it is possible to print file properties, like EXIF data, name and location, on the corresponding image. It is also great that you can preview all changes in real time. Likewise, it is an absolute advantage to be able to reuse watermarks on other sets of pictures.

All in all, UMark can come in handy when you need to identify bulks of photographs. Therefore, its main asset is undoubtedly its support of batch operations and its incredible speed. The product is available in two versions: Free and Pro.
