Is the Windows Photos app slow, or does it refuse to open HEIC, PSD or WebP files? 123 Photo Viewer, now listed in the Microsoft Store as 123 Photos, opens more than 60 formats with hardware-accelerated zooming and can also crop, rotate and convert them.
Gallery browsing
Browse a folder as a gallery or step through it one photo at a time. Hardware acceleration keeps zooming and panning smooth even on large, high-resolution pictures, and any folder can be played as a slideshow.
Beyond JPG, PNG, GIF and BMP, it opens Apple HEIC photos, WebP, camera RAW, Photoshop PSD, Illustrator AI and PDF files, and even DICOM medical images.
Which image formats can it open?
That makes it handy for iPhone photos copied to a PC, design files from colleagues, or RAW shots straight off a camera card.
- Open photos one at a time or together as a gallery.
- Select an image to bring up its editing settings.
Basic image adjustments
Selecting a snapshot gives access to editing controls for changing its appearance. The built-in editor includes cropping, enlarging, and rotating, along with retouching options for elements in the photo.
Edited images can be saved in another format, and batch conversion turns a whole set of files into JPG, PNG or other formats in one go.
