You can download the most recent version of CODIJY Colorizer Pro & CODIJY Recoloring from the Downloads page.  

If you have installed CODIJY trial, there is no need to download CODIJY software once again! All CODIJY tools run in the trial mode for the first 15 days, unless you register them with the License Key.  

After the recent update, some of our users have noticed that Windows Smart screen blocks the download of our software in Edge browser. We guarantee that our products are 100% clean and were duly signed by the valid code signing certificate issued by COMODO,  the authorized security organization. To fix this upsetting situation, we have timely submitted our files for review to Microsoft and they cleared all of them as clean. Still some of our users keep experiencing the problem with downloading CODIJY. If you happen to face it, please use any other browser to download CODIJY software.  You can also learn how to bypass the security filter in Edge from this article by  Windows Central

Uninstall your copy of CODIJY from your old computer and then download the CODIJY software to the new computer and register it with your key.   

Despite the fact that CODIJY software has been duly signed with certificates issued by the authorized organization, Microsoft’s new policies require every new file to gain reputation via large amount of downloads and installs. Unfortunately the recent CODIJY update 4.1 (released on 16.08.2021) is still in the process of growing its “reputation” with Windows Defender. Please read how make Windows respect your wish to install CODIJY software.  

CODIJY software is 100% clean. Still, once in a while we receive complaints that antivirus is blocking the installation of this or that CODIJY products. We understand your concerns and want that you had only the best experience with our products.

We recommend that you save your work to the CODIJY document. The CODIJY files (MGD) save the image along with masks and history of colors for anytime reference! 

To edit your colorized image in any other software, export the color preview to the PNG or any other image format supported by the software you are going to work with.  

Colorization Process
  1. Use Libraries – Libraries were designed to provide quick reliable reference of tones for each subject. 
  2. Practice using Quick-Draw  hotkeys
  3. Use partial processing instead of full image processing.
  4. Use Instant Preview for small areas
  5. Capture natural colors and gradients from the color images for faces.
Color Picking

We are not adding the color opacity control options, as you can achieve same results by adjusting Hues, Saturation and Brightness.  Many of our users who asked for this function finally found the HSB Repaint tool as useful for this purpose.  

After you have drawn a gradient stroke, you still have the option to fill it with another, best-matching gradient template. Once you are satisfied with result,  apply your last chosen gradient with the click of the button in Gradient Settings or press “B”. 


Strokes/Masks Drawing

Draw the mask close to the area boundary to make sure the program recognizes its location correctly. 

You can read the detailed description about the mask drawing process in the How to Draw Color Masks guide. 

You can protect areas by drawing a protection mask. we recommend covering the area completely with the brush of the large size. 


Just outline the areas with the Decolor pen

The mask will have the following pattern


Step 1. Draw gradient following the same rout you have captured it or you wish the gradient colors to apply to. 

Step 2. Then click Apply Gradient in Gradient Settings or press B

Preview & Color Results

Click Image Processing or press Ctrl+R

The program will start generating the result

Image processing

CODIJY products are pretty accurate about treating boundaries in case you draw the mask on the both sides of the boundary and the border is clear. 

At times the colors may spill across the boundary at the areas where the algorithms are unable to recognize it. As you can see in the screenshot there is a spilling of the yellow color on the wing (marked with the circle). The colors from the plane spread out over the background land as we have not yet added masks to these areas. 

SOLUTION: Add the strokes closer to the border. 

CODIJY converts all images to grayscale before colorization automatically. It does not mix new and original colors. instead programs algorithms work with the grayscale image to apply new colors.  


1. The image is too large. 

Option # 1 Colorizer Pro users have the option to use a small-size version of the image to add masks. After that you can export the mask and import it into file with the full-size original photo. The masks will adjust their size automatically. 

Option # 2. Use partial image processing to generate the color preview for the small area you are working upon. 

2. Your computer lacks RAM

CODIJY is very demanding on the amount of installed RAM. And unfortunately, the lack of RAM in some cases can lead to crashes.
In simple terms, the more RAM you have, that its the better.
We are working on eliminating these problems, but you also can help himself.
The tab “Undo & Temp files” in application preference contains two checkboxes for that:
– “Dump Undo/Redo data onto disk”
– “Enable Undo/Redo data compression”
“Dump Undo/Redo data onto disk”: This allows CODIJY dump undo/redo operations on the disk instead of keep it on the RAM. It may help save more RAM for the other tasks (for example for the processing), but it’s slowdown undo/redo operations.
“Enable Undo/Redo data compression”: This allows CODIJY compresses undo/redo data, which also allows saving more RAM.
Depending on the state of “Dump Undo/Redo data onto disk”, it compresses data in RAM or when it dumps it on the disk.
I do not recommend enabling both of them because it may significantly slowdown undo/redo operations, but enabling one of them may help you if your computer does not have much RAM.
