Why AI restoration took off
MyHeritage's Photo Enhancer processed a million photos in about ten days after it launched in June 2020 [1]; the company later added Photo Repair for scratches and tears, licensed from the DeOldify project [2]. Google made Photo Unblur free for every Google Photos user in 2024 [3]. Restoration went from a specialist retouching job to a one-tap feature in four years.
What the AI is actually doing
Face-restoration research such as GFPGAN rebuilds eyes, skin and hair from a learned “face prior” [4]; scratch and stain removal is inpainting, filling damaged areas from their surroundings [5]. Both are educated guesses — excellent for family albums, but compare faces with the original before you print.
Keep the original scan
Archival guidelines keep master scans untouched: FADGI says dust removal and colour restoration belong on a separate copy, never the master file [6]. Whatever tool you choose, restore a copy.
