Colorize Images is an automatic Machine Learning based service to colorize black and white, grayscale or nightvision photos.
The black & white photo for the colorization can be selected from the gallery, or it can be shared from the other applications such as Facebook, Chrome or Google Photos. The colorful result image can be shared to the other applications, or saved into the gallery.
No watermarks nor any other additions are made to the images!
All the functionality of the Colorize Images application can be used for free for the first 10 colorizations. The use after the trial period requires purchasing a monthly subscription.
The monthly subscription rate is about $1.50 depending on the local taxes etc. The exact rate for your country/state is shown in the app. The active subscription allows unlimited number of colorizations.
The service uses network data and external GPU capacity to provide the colorization functionality. This means that the source images are sent to a remote location over the network, colorized there and the resulting images are then received from the remote location over the network.
For the best result, the source image is recommended to have:
and correct orientation
The images not having all these properties may also work fine, but some preprocessing (like contrast correction or sharpening) usually improves the result.
