Word Convert Image to Black and White: 4 Ways
Yes, Microsoft Word can convert an image to black and white, and you don’t need any external software. You can do it in a few clicks using the built-in picture tools, and the result is a permanent change to the image inside your document. This article shows you the exact steps for Windows, Mac, and Word for the web, plus what to do if the option is grayed out.
Why Convert an Image in Word?
You might want a black-and-white version of a photo for a formal report, a printable handout, or to match a document’s monochrome theme. Converting in Word is convenient because you don’t have to open a separate photo editor, and you can always undo the change if you haven’t saved and closed the file. However, Word’s conversion is a simple desaturation—it removes color information but does not let you adjust contrast, brightness, or individual color channels like a dedicated editor would.
Method 1: Use the Color Saturation Preset (Windows and Mac)
This is the fastest and most reliable method in the desktop versions of Word.
- Click the image you want to change. A Picture Format (or Format Picture) tab appears on the ribbon.
- Click that tab.
- Find the Color button (in the Adjust group).
- In the drop-down, look for the Recolor section.
- Choose the first thumbnail, which is labeled Black and White (it’s usually the very first option in that grid).
Your image instantly becomes grayscale. The change is applied to the picture itself, not to the page background or the document’s theme. If you later want the color back, repeat the steps and choose No Recolor (the top-left thumbnail in the same Recolor grid).
Method 2: Use Picture Transparency (Word for the Web)
Word for the web (the free browser version) does not have the Recolor feature. As of now, you cannot directly convert an image to black and white in the online editor. The only workaround is to edit the image before you upload it—use a free online tool, a phone photo editor, or a desktop app—then insert the edited file into Word Online.
Method 3: Insert a Black-and-White Image File Instead
If you need a true grayscale image for other uses (like a PDF or a presentation), the best approach is to convert the original file once and then insert it. Here’s a quick way using Word itself:
- Insert the color image into a blank Word document.
- Apply the Black and White Recolor from Method 1.
- Right-click the image and choose Save as Picture.
- Choose a location and file name, and pick a format like PNG or JPEG.
The saved file is permanently grayscale, and you can use it anywhere. This is handy if you want to reuse the converted image in another document or on a website.
Method 4: Use a Built-in Filter in the Insert Dialog
On Windows, when you insert a picture via Insert > Pictures > This Device, the file picker has a small toolbar. Click the Filter icon (a funnel) and choose Black and white. This only filters the view in the file dialog—it does not convert the image. You still need to apply the Recolor after inserting. This method is useful if you have many images and want to preview them in grayscale before choosing one.
What to Do If the Color Button Is Grayed Out
If the Color button is unavailable, the most common cause is that you haven’t actually selected the image. Click directly on the picture—you should see small squares (handles) around it. Another cause: your image might be inside a drawing canvas or a group. Ungroup it first (select the group, then Group > Ungroup), then select the individual image. Also, make sure you’re not in a compatibility mode for an older Word version—save the document in the current .docx format if you see a “Compatibility Mode� label in the title bar.
How to Adjust the Result (Contrast and Brightness)
Word’s Recolor simply strips color, but you can tweak the result with the Corrections button (next to Color). It offers presets for brightness and contrast. For finer control, click Picture Corrections Options at the bottom of that menu. A sidebar opens with sliders. A good starting point for a scanned document or a photo with gray background is to increase contrast slightly (e.g., +10%) and reduce brightness a bit (e.g., -5%). This makes text or subjects pop. Remember, these adjustments are non-destructive—you can always revert to the original.
Common Mistakes and Misconceptions
- “Print in grayscale� vs. converting: Setting your printer to grayscale prints a color image without changing the file. The image in Word stays colored. Converting changes the actual image data.
- “Black and white� vs. “grayscale�: Word’s Black and White preset produces grayscale (shades of gray). It does not create a two-tone black-and-white image (only pure black and white pixels). For true 1-bit black and white, you need a photo editor.
- Undoing after saving: If you save and close the document, the Recolor is baked in. You can’t undo after closing. Keep a copy of the original file if you might need color later.
- Vector images: If you insert an SVG (scalable vector graphic), the Recolor option works, but the result may look different because SVG colors are defined differently. It still works, but test it.
Frequently Asked Questions
Can I convert multiple images at once? No, Word only applies Recolor to one image at a time. You must select each image and repeat the steps. There’s no batch feature.
Does the conversion work on shapes or SmartArt? Yes, on shapes with a picture fill, you can select the shape and apply Recolor. For SmartArt, you need to click the specific picture inside the graphic first.
Will the black-and-white version print correctly? Yes, it prints exactly as you see it. If you set your printer to grayscale, a converted image might look slightly darker because the printer applies its own conversion—but the file itself is already grayscale.
Can I convert an image to black and white in Word on a phone? The Word mobile apps (iOS and Android) have limited picture formatting. As of now, they do not include the Recolor feature. You’ll need to use a separate app or the desktop version.
Does converting reduce file size? Sometimes, but not always. Grayscale images can be smaller than color, but Word’s compression settings and the image format matter more. You can reduce file size by using File > Compress Pictures.
