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 file. Every pixel should be either black, or white.
I don't just want a monochrome image. I can't have varying shades of gray, every pixel needs to be black or white.
Is this possible? I looked under Image > Mode but nothing there seems to indiciate a binary style image.
After using Image > Mode > Grayscale to convert to a grayscale image, youâ€™ll be able to now select Image > Mode > Bitmap, which does exactly what youâ€™re after.
Many of Photoshopâ€™s functions arenâ€™t available in bitmap mode, but hopefully thatâ€™s not an issue. If it is, you can run them when still in grayscale, then convert to bitmap.
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.
