Ten Image Colorizer Tools FREE&PAID [2020]

There are a few things in the world as precious as old pictures with large sentimental value. They help us relive joyful moments over and over again, regardless of their age. Unfortunately, the restrictive shades of black and white can often prevent us from fully appreciating them.

In order to nullify the negative effects of aging, image colorization was introduced. This method essentially breathes new life into the pictures, helping us visualize and refresh the memory of that particular event. While this was significantly harder to execute in its early stages of development, it has since become virtually automatic. With a large number of available tools to colorize black and white photos, it can be hard to pick just one. The following ten are some of the best of the bunch – read on to find out why.

Image Colorizer 

If you’re a fan of hands-free methods, Image Colorizer is as automated as they get. This AI-based utility does all the hard work directly from its website without any sketchy downloads. Even though the machine learning algorithms analyze the image pixel by pixel, the whole process lasts no more than a few seconds. The self-explanatory interface means that anyone can use it with ease, regardless of their technological literacy. Image Colorizer is a FREE online tool, so you don’t need to worry about being charged. In addition, there is a downloadable app for both Android and iOS to maximize your time savings. Thus, this is a perfect tool to colorize black and white photos.

The program is used from the browser, with a free version for personal use and paid alternatives for teams and enterprises.

Lunapic

Unlike most of the other tools on the list, Lunapic is more than just a colorizer – it’s a full-fledged photo editor. It features over 200 different effects, drawing tools, borders, etc. The colorizing option itself is automatic, although users have the ability to modify the potency of colors.

Usage Guide

– Some of the options are difficult to find

– Takes a long time to process

– The color is weird

ColouriseSG 

Simple but aesthetically pleasing, ColouriseSG uses deep learning models in order to colorize the pictures. Although it’s primarily made for old Singaporean photos, ColouriseSG is quite efficient with any image as long as it’s of a somewhat high resolution and has prominent human subjects/landscapes.

Pros

+ Very attractive and simple interface

+ High-quality results

Cons

– Targets very specific images

Pinetools 

Pinetools is a mix of fully manual and fully automated tools. However, this tool is more like adding a filter to the image instead of colorizing it. The user selects a color from the color palette, as well as its potency in the final image. Pinetools supports three image formats -.PNG, .JPG and WebP. After you choose a color, the tool does the rest automatically.

Pros

+ A good combination for those who like to have some control

Cons

– Only one color can be selected per picture

– No option to upload multiple images at once

Colorize Photos 

Yet another tool that relies on deep learning technology, Colorize Photos uses neural networks to teach its algorithm-specific image patterns in order to improve the coloring quality. The whole process takes only a few seconds, after which you get a temporary URL where you can download the final result.

Pros

+ Fast results

+ Quick and easy to use

Cons

– Generated URL’s only work for 10 minutes

Pros:

+ Fast and easy to use

+ Free online tool, don’t need to download

Cons:

– Only allowed to upload an image of no more than 1200px

Pixbim 

Even though it’s another AI-powered tool, Pixbim is fairly different from the previous entry. The largest dissimilarity is its variable efficiency which heavily depends on your PC’s processing power. Also, larger images can take a very long time to process in most cases. Pixbim has a fairly limited free version, while the paid one costs a whopping $39.99.

Usage Guide

  1. Select a single or bulk of images from the menu.
  2. Choose between low and high color factor.
  3. Click on the “Start Process Full Image and Save” button.

Pros

+ Powered by AI

Cons

– Free version watermarks images

– Very expensive

– Requires a good PC to be efficient

– Do not have an online version

Photoshop

As with pretty much all image modifications, colorization was first practiced in Photoshop. While it’s one of the most professional approaches that you can resort to, Photoshop by itself is very feature-packed and complex to use. For an amateur user who simply wants to improve an old image or two easily and efficiently, this process can be quite challenging. Still, it’s not a bad choice if you’re someone who likes to have control over the entire procedure.

Pros

+ A lot of options

+ Full control to the user

Cons

– Very complex for beginners

– Manual colorization can take a long time

Colorize Photo 

If you’re looking to use Photoshop’s approach without its complexity, Colorize Photo is the tool for the job. This browser-based utility relies on both the black & white image as well as a reference photo and leaves the full coloring process to the user. The brush has a lot of customization options – specifically for its size, hardness, opacity, and brightness. However, it can be hard for beginners to choose the right color.

Usage Guide

  1. Upload the reference and black & white image.
  2. Select color and paint the appropriate area.
  3. Save the final result.

Pros

+ Feature packed

+ Useful for experienced users

Cons

– Beginners can find it difficult to color properly
