Derustify

Derustify runs AI‑driven photo restoration entirely on Windows or Android devices, processing images locally without any cloud service or subscription. It denoises, removes scratches, heals tears, and sharpens faces while preserving fine details, and can also colorize black‑and‑white pictures with realistic hues. The software includes a smart perspective scanner that auto‑detects edges and corrects lens distortion, allowing a phone to act as a flat‑bed scanner for whole albums.

The tool targets users who want to preserve personal or historical photographs offline, offering batch processing for large collections and manual wavelet‑based controls for fine‑tuning structural clarity, detail recovery, and film grain. All operations are hardware‑accelerated, running on the user’s own CPU or GPU, which keeps the workflow fast even on everyday devices.

Because no data leaves the device, privacy is maintained; there are no accounts, servers, or external storage involved. The application is offered for free with an optional one‑time purchase for unlimited high‑end results.
