When working with corrupted JPEGs, make sure you duplicate your problematic image, leaving the original intact. It may also be useful to try opening your image using some other photo viewer and/or transferring it to a different computer in order to see if there is anything wrong with the current software. It could also be helpful to check if any backup of your image exists in the cloud or on another drive. When the problem persists, a professional repair tool will definitely come in handy. However, do not edit or save the corrupted image again as this could only worsen your situation. Regularly making copies of all your photographs would also save you from losing your valuable files forever. If you need an effortless way to recover your images, try Notchox.
