How to Colorize Images Online

What is Colorization?

Colorization is the process of converting grayscale images into color and inferring color where it is missing. Technically, this means assigning RGB (Red, Green, Blue) color information to each pixel based on the intensity of a grayscale image.

Over the last two decades, many colorization methods have been developed, from simple (but time-consuming) approaches to more complex, automated methods. Automatic conversion is now an active field that uses machine learning and deep learning.

Why Should I Colorize Images?

Black and white images may have exceptional artistic value, but color is an essential component of visual representation. Color images trigger emotional responses. People can relate to the image in a way they could not before.

One of the main uses of colorization is restoring historical black and white images. For old family photos, excellent results can be achieved by using image colorization.

Use of Photoshop for Colorization of Images

The most commonly used tool for colorizing black and white images has long been Adobe Photoshop . It offers a wide range of tools to add color to objects in a photo, enhance the image, and make it look like it was originally taken in color.

However, the image is colored based on personal perception of what the colored version should look like. When done by hand in Photoshop, it can take up to a month to colorize an image. In addition, extensive research may be required to get it just right.

In contrast, a machine learning algorithm can learn with a certain degree of accuracy to map black and white pixels to RGB pixels and automate the colorization process. Our online tool uses AI-based machine learning algorithms and lets users colorize their black and white photos quickly and easily online.

How does this work?

Colorizing black and white images with deep learning is one of the key applications of neural networks . Neural networks handle incomplete data well, so color can be added successfully even if the photos are not in perfect condition.

Machine learning makes major progress when you replace hand-coding with learning by the machine. To achieve realistic image colorization, specific algorithms and trained models are used to replace a hand-coded loss function with a network that learns everything needed.

Thanks to AI technology, our image colorization tool can recognize the scene and its elements, look up a relevant database, apply colors to these elements, and compose the scene. Since black and white photos do not actually contain any color information, this tool uses machine learning to estimate the tones in an image.

How To Automatically Colorize Images Online?

Powered by advanced AI technology, our image colorizer can automatically colorize black and white photos by analyzing the objects in a photo. No manual editing is necessary.

Follow the steps below to colorize your image in just a few seconds.

1. Visit Img2Go.com - Colorize Images tool.
2. Click "Choose File" to select an image file to upload. You can also drag and drop the PDF file. You can also upload a file from the Internet (Enter URL) or from cloud storage (Google Drive, Dropbox).
3. Choose any optional settings to improve the final result.
4. Click the "Download" button to save the image.

Optional settings explained:

• Target Format: PNG, TIFF (select one of these two formats).
• Choose an AI training model - Depending on your image content, selecting a training model can improve the result. Choose between the "Nature and People" option (algorithms here were trained mostly on nature images, such as forests, lakes, landscapes, and human portraits). Or choose the "Generic" option (algorithms used here were trained on everything else, e.g. a car, a city view, etc.).
• Set render factor By increasing this value you can improve the quality of the resulting image.

Conclusion

Adding color to black and white images is not a difficult task, especially now that you have read this article and learned how to do it automatically online and get the best results for free. Go through your family photo albums, find black and white photos, and turn them from monochrome to color , regardless of any flaws in the image. You will be pleasantly surprised by the results!
