PhotoScape is a tool that lets you view / edit image files with rich possibilities to enhance their appearance.
Becuase this is a portable product, PhotoScape does not need to be installed, so your Windows registry entries remain intact. It also means that you can run Portable PhotoScape directly from an external drive.
The interface attracts users with any experience level. In the main window, there are a few options displayed in a circular menu, and on the left you can view various images imported from Flickr.
So, you can use a viewer, editor and batch editor, customize pages (size, margin, background, frames, filters), merge photos (via drag and drop), create an animated picture (GIF), print photos, split pictures into several parts, take a snapshot (capture window, region or full screen), use color picker and a RAW converter, and rename files (including file, photo and today's date).
In Viewer, you can create a slideshow, view in full screen mode, use lossless rotation, delete or rename files, and delete EXIF info, while the Editor lets you adjust brightness, contrast and white balance, rotate images, use backlight correction, apply the antique or film effect, use item decoration, remove moles, reduce noise, bloom, use a colored or watercolor pencil, distort, apply linear gradient, reflection, clone stamp, and more. There are hotkeys assigned for both the Viewer and Editor's functions.
The program uses significantly less system resources than the installed version of PhotoScape, and has easy-to-follow video tutorials, but it still lacks advanced image editing settings. Nevertheless, Portable PhotoScape is a great tool to use after you get familiarized with its unusual but intuitive interface.
