XDenSer Image Shrink

XDenSer Image Shrink is a tiny and portable application that you can use to quickly resize graphic files. It offers support for JPEG format only and contains simple options.

Portability advantages

The entire program's wrapped in a single .exe file that you can save to a custom location on the HDD or to a USB flash drive, and just double-click to launch XDenSer Image Shrink on any PC effortlessly and without previous setup.
It doesn't create files on the disk without asking for your permission, need DLLs to run, or add new entries to the Windows registry.

Simple interface for resizing images

Regarding the GUI, the tool adopts a normal window with a plain appearance and clear-cut layout, where you can resort to the file browser to locate a JPEG object. Unfortunately, batch processing isn't supported, so you're restricted to working with only one file at a time.
It's possible to preview the original and new picture in the main window, select a percentage level from the drop-down menu to take into account for the image proportions, as well as preview the new file size and resolution (height and weight).
Worth noting is that no modifications are made to the original pictures, so there's no need to create backups prior to using this program. Instead, you can specify the destination folder and name of the new file. If you have an associated email client, you can directly send the photo as a file attachment when composing a new message.

Evaluation and conclusion

It worked smoothly in our tests, without hanging, crashing or prompting error messages. Tasks were carried out fast while resources usage was minimal. However, XDenSer Image Shrink doesn't support batch processing, additional resizing methods (e.g. by height and width), or more file extensions (e.g. PNG, BMP, GIF).
