: How do you make a binary image in Photoshop? I am trying to make a binary image. I want more than just the look of the image to be black/white, but I want the actual file to be a binary

@Jennifer810

You can try this:

1 - change the image mode to Grayscale (top menu Image > Mode > Grayscale)

2 - open Image > Adjustments > Threshold. That will allow you to adjust which parts of the grayscale will be converted to black or to white, making your image truly binary.

From the Adobe help:


The Threshold filter converts grayscale or color images into high-contrast, black-and-white images. You can specify a certain level as a threshold. All pixels lighter than the threshold are converted to white; and all pixels darker are converted to black. The Threshold command is useful for determining the lightest and darkest areas of an image.

Check out Image Trace in Adobe Illustrator.

I like using python and PIL, however.

from PIL import Image
image_file = Image.open("myimage.bmp")
image_file = image_file.convert('1') # convert
image_file.save('result.bmp')

After using Image > Mode > Grayscale to convert to a grayscale image, you’ll be able to now select Image > Mode > Bitmap, which does exactly what you’re after.

Many of Photoshop’s functions aren’t available in bitmap mode, but hopefully that’s not an issue. If it is, you can run them when still in grayscale, then convert to bitmap.
