About the Bulk Photo Enhancer
The Img Stop Bulk Photo Enhancer improves whole batches of pictures automatically. It analyses every photo separately – stretching contrast, fixing color casts, brightening dark areas, boosting dull colors and adding clarity and sharpness – so each image gets the correction it needs, not one fixed filter.
Pick a style that suits your photos, fine-tune the sliders if you like, and compare before and after with the slider on any image. You can also enlarge photos 2× or 4×. Everything runs in your browser, so even private photos never leave your device.
