About this app

Colorize Images is an automatic Machine Learning based service to colorize black and white, grayscale or nightvision photos .

Please note: If you have any questions or issues, send me a debug message by using the Report Bug feature in the app. The message includes information to help in solving the issues. Thank you!

Black and White images do not contain any clues about the correct colors. The colorization of the photos is determined by the training of the Machine Learning model, but the model does not know the context of the photos. The selected colors are not historically accurate and not necessarily correct.

The black & white photos for the colorization can be selected from the gallery, or they can be shared from the other applications such as Facebook, Twitter, Chrome or Google Photos. The colorized result images can be shared to the other applications, or saved into the gallery.

The app can be used for free by watching Ads. Subscribing the app allows unlimited number of colorizations without interruptions during the subscription period.

The service uses GPU servers to provide the colorization functionality. This means that the source images are sent to a remote location over the network, colorized there and the colorized images are then received back to the device.

For the best result, the source image is recommended to have:

• good quality
• good contrast
• good focus
• and correct orientation

The images not having all these properties may work fine, but some preprocessing (like contrast correction or sharpening) usually improves the result.

Based on DeOldify project.

Wow!! I was super sceptical when I saw this app, because I often painstakingly colorize photos in photoshop. I thought there was no way a machine learning app could do this. Well, I was wrong. You have to mess around with the settings a bit (I recommend lower render setting numbers for portraits of one or two people, and higher for groups), but once you figure it out you can get amazing results. So happy I found this app, bought the lifetime access. Thank you developers!

Way better than I was expecting. On certain images it's not 100% perfect but still I'm not going to knock off a star just for such a minor thing. It does really well with images of humans, animals, and land scapes. I tested it on some black and white art as well and it's cool looking at what colors the app puts in there. On things that aren't really meant to be colorized it picks a warmer color scheme using shades of yellow, orange,and red. I recommend this app over others that are online.

My APOLOGIES to devs for prematurely poor review. I played with the app, and with better B&W photos, got GREAT colorized versions. Good example of assuming too quickly. I'll bet others did as well, hence lower rating. BEST colorizer app I've found. B&W ideally should be hi-res and sharp. Anything less-than in quality won't be read well. I'm in for annual fee of $10 for unlimited! HIGHLY RECOMMEND. Put crappy photos in, you'll get poor quality back.

Thank you for the feedback! It's great to hear that you got it work with your photos! It's true that the low quality photos are difficult for the model. That's why it's always recommended before colorization to make sure that the contrast and brightness are best possible and the orientation is right. That may improve the result even for bad photos.

What's new

* minor fixes

* new colorization model released
