If you have images of nonstandard color (for example, scanned copies of books with unusual background and font colors or screenshots of programs with unusual color settings), and you want to standardize them (create black font on white background) you can do it at once with the help of Image Converter Plus.

Do the following:

Step 1:

  • Launch Image Converter Plus.

Step 2:

  • Go to “Photos” tab, select and add images you want to process.

Step 3:

  • Go to Profiles tab. In “Operation before save: Add operation” line, click “Add operation” and select “Color Effects” from the menu.

Step 4:

  • If your images contain light font on dark background, repeat step 3 once again.

Step 5:

  • Click once again and select “Replace Color” from the menu.

Step 6:

  • Repeat step 4 once again.

Step 7:

  • Click “+” mark located to the left from “Add operation” line to open the group of settings for added operations.

Step 8:

  • In “Color Effects”, select “Grayscale” effect in “Apply : Effect” line.

Step 9:

  • In the second instance of “Color Effects” (if it exists), select “Negative” effect in “Apply : Effect” line.

Step 10:

  • In the first instance of “Replace Color”, select “black” and “black” in “Replace color : with color :” line. Enter a value from 60 to 70 into “with tolerance : %” line (the value should be empirically selected). Deactivate “Smoothing” checkbox.

Step 11:

  • In the second instance of “Replace Color”, select “white” and “white” in “Replace color : with color :” line. Enter a value from 30 to 50 into “with tolerance : %” line (the value should be empirically selected). Deactivate “Smoothing” checkbox.

Step 12:

  • In “Save images in …. format”, select GIF format as as the most suitable one for the case. It will also help reduce the size of the files.

Step 13:

  • In “With : colors”, select “2”.

Step 14:

  • Specify other settings for the format (optimal values are specified by default).

Step 15:

  • Specify the folder to save converted images to.

Step 16:

  • Specify other settings.

Step 17:

  • Press “Start” button to start conversion.
