BDSizer

BDSizer is a piece of software which can help you perform several operations on images, including resizing. It supports a wide range of extensions, such as BMP, EMF, JPG, ICO, PSD and TGA.
Since this is a portable tool, there is no installation package. In other words, you can save BDSizer to a USB flash drive or any other removable device, store it on any computer and directly run its executable file. More importantly, no items are left behind in the Windows registry or on the hard drive.
The interface of the app is user-friendly. Pictures can be imported by using either the file browser or 'drag and drop' method. There is also a batch mode available, so you can process multiple items simultaneously.
BDSizer lets you resize the picture by selecting the method (Smart, Lanczos3, B-Spline) and new value in pixels. But you can also apply watermarks and configure settings (e.g. position, size, offset, rotation, transparency), add copyrighted text and establish the size of the new picture, along with its filename.
Additional information of the photograph can be edited in regard to the description, creator, content and technical. Is is possible to use the undo function, preview the image and zoom in/out, as well as to rotate it.
The image processing application uses a moderate amount of CPU and system memory, is pretty responsive and quickly finishes a task. We have not come across any errors during our tests and BDSizer did not freeze or crash. Unfortunately, the piece of software does not support format conversion. First-time users may need some time to adjust to the layout.
