jpgHD is a sophisticated tool designed to implement lossless restoration of old photos using advanced machine learning models. The tool is devised to rejuvenate old pictures by handling issues such as scratches, faded colors, and damaged parts.

One of its notable features is the colorization of older photos, bringing them to life in new, vibrant color schemes. The application also hosts the 'Magic Photo' feature that aims to create lively transformations of static portraiture.

The tool employs a line-up of the most advanced AI image super-resolution models and deep learning technology. Recovery of an image typically takes between 3 to 5 minutes, depending on the specifics of the image like its size and the number of faces in the photo.

The tool also offers a 'Pro' version that provides priority processing, unrestricted upload sizes, higher resolution outputs and numerous additional features.

The service caters to a broad user-base with applications available for iOS, Android, Windows, and MacOS, and the processing algorithm is offered via an API as well.

The algorithm maintains robust security practices, deleting data over 3 days old to prevent data leakage.
