Apowersoft HEIC Photo Viewer is a free photography app that can open and view HEIC images. HEIC (or High-Efficiency Image File Format) images are especially used by Apple devices, and cannot be easily opened by any non-Apple device that has no app supporting the format. With this photo viewer, not only can you open the images, but you can also edit them as if they’re simple image files. You can zoom in and out, use your mouse wheel to scroll through numerous images, and even start a slideshow. Apowersoft Photo Viewer can also open other image file formats, such as JPEG and PNG.
