If you're looking for a service that uses AI to remove scratches and other artifacts from old photos, there are plenty of good options. ImageColorizer is notable for its suite of tools to restore and improve old photos. That includes AI Repair that specifically removes scratches and other detritus, and a "magic eraser" option for more fine tuning. The service offers a range of other improvements, including colorization, upsizing and clarity, and has flexible pricing with a free tier.
Another option is Remini, which is geared specifically for turning low-resolution photos and videos into high-resolution images. Remini can fix problems like blurriness, camera shake and focus, and restore old, yellowed or damaged photos to their original state. It also can upscale photos and offer professional-level realism, making it a good option for social media, heritage preservation and print services.
Nostalgia Photos is geared specifically for historical photo restoration, using machine-learning algorithms trained on thousands of historical photos. It offers multiple restoration options for each photo, upscales to high-definition resolution and deletes processed photos after 24 hours for privacy. That makes it a good option for people who want to preserve and share historical photos at the highest quality.
For a broader range of photo enhancement options, PicMa offers specific options for different types of photos, including old and portrait photos. Its Descratch feature is geared specifically for removing creases and scratches, but other options like Enhance PRO and AI Eraser offer other ways to improve image quality.
