If you don't like the Windows 10's Photos app, you're not alone. The good old Photo Viewer was better and faster, in the eyes of many Windows users.

But, there are many applications which offer more options including PicView, IrfanView, Wildbit Viewer, XnView, or FastStone Image Viewer. CPix is a compact freeware image viewer and converter that offers a fluid experience.

The program's interface is minimal, it starts blank and has a menu bar at the top of the window. Open a photo by using the file menu or the right-click menu, or drag and drop an image onto the GUI.

CPix supports the following image formats: PNG, JPG, GIF, BMP, WebP, JPEG, JPE, JFIF, JFI, JIF, TIF, TIFF, WBMP, EJPG, MPO, EMPO, PL, EPL, PBM, PGM and PPM.

CPix supports encrypting JPG images to the EJPG format created by the developer, Filefriend. You can convert images from JPG to EJPG or the other way around from the EJPG menu or the File menu. Select an image and the folder it has to be saved in, enter the password to be used for encryption and click on the JPEG > EJPG button. To view the encrypted image, open it in CPix and use the password.


Despite the name, DualPhoto doesn't stitch two images together. It is another format from the developer, which contains two JPG images in the same file. To create a new dual photo, click on the JPEG > DualPhoto menu item. Select the two images, the output folder and set a password for the images. You can use Cpix to switch between the two images in the file.

    If you’re low on RAM there’s a very small but very capable image viewer “Imagine”. Weights probably around 1 MB and supports extension if you want to open many less common files. The drawback of being so lightweight is obviously the looks but still an amazing feat.
