Adobe Photoshop Express
You can quickly edit photos on your Windows PC or tablet.
You can do the basic photo enhancements such as crop, straighten,
rotate, flip, or remove red-eye. You can adjust color, contrast, and
brightness all at once. You can also use “slider controls” to enhance
contrast, exposure, and white balance, or let the app auto-correct it for you.
You can download it as an app for Apple, Android or online
