Let’s now paste that image in MS Paint: no problem, all colors are kept. So far, this unsaved, pasted picture is maintained “in memory”. Colors and image quality are affected only once you save the file, because the file format determines how many colors and what compression should be applied. Saving a JPEG in Paint compresses by roughly 20%. In other words, you end up with a picture that is 80% of the quality of the original (screenshot is zoomed in).
To convert your image to black and white, click on the blue Paint button (top left corner) and choose Save As on the left. In the Save as type dropdown, select Monochrome Bitmap (monochrome means “a single color”). Because Paint uses by default a black foreground over a white background, your image is now converted to purely black and white. The result for our test image is shown on the screenshot: just two colors, few details, and no gray scale.
Click the “Grayscale” button to change the colors in your photo to shades of gray, or the “Sepia” button to give it a brown tint. If you are not happy with the change, click the “Undo” button in the top row.
Click the “File” menu at the top of the Paint window, and select “Open.” Browse to the location of the photo that you would like to convert and double-click it. Alternatively, drag the photo into the open Paint window and drop it.
Notice how rich, colorful, and detailed that painting is: it’s not the best choice to convert an image to black and white, and this is why I chose it. It will illustrate Paint’s limitation. For less complicated artwork though, it will do just fine! As example, this screenshot shows a “desaturated” (grayscale) version of that image, with the desaturation filter applied with Adobe Photoshop. The colors are lost, but all the details are kept, and that file can be saved in any format.
Launch iPhoto from the dock or “Applications” folder. If you haven’t added the photo to your iPhoto library already, drag the photo to the open iPhoto window to import it.
As one of the oldest programs to be bundled with Windows, MS Paint supports a wide array of formats. But it’s limited in its output: unlike professional graphic editors like Photoshop, you can’t control the compression or quality of a JPEG photo. But thankfully, Microsoft kept support for older file types, and one of those allows you to convert and save any picture in black and white! For reference, this screenshot shows the original picture I’ll use in this tutorial.
Click “File,” then click “Save As.” Save your image to a new location to preserve the original photo. Changing a color photo to black and white in Paint changes it to a monochrome image with only two colors. This may cause some loss of detail. To change the photo to a more natural looking grayscale image instead, see Section 2.
Click the photo that you want to convert to black and white, and then click the “Edit” button at the bottom of the window. A larger version of the photo appears in the window.
Click the “Image” menu at the top of the Paint window, and select “Attributes.”
Click the “B&W” button to convert the photo to a grayscale image, or the “Sepia” button to add brown tones. The color will change immediately. If you are unhappy with the new appearance of the photo, click the “Original” button in the middle of the “Effects” window to revert the image.
To get the best quality picture for a file you plan on sharing online, choose to save it from Paint as a PNG. This is the best compromise of quality and compression (smaller file size). To share it with other Windows users over a network, a 24-bit Bitmap file is the richest, lossless image format that MS Paint supports. Pictured are the formats supported by Paint on Windows 7 / 8 / 10.Tip: to interchange black and white, know that you Paint can invert colors!
Although black and white photography is largely unused in today’s era of affordable digital cameras, you might like the look of black and white photos, or may simply be looking for a way to do something different with a picture that you are uploading to a social networking website. Whether you have a Windows PC or a Mac, you already have the tool that you need to convert your color photos to black and white.
Create a black and white photo with the tools on your computer.
Browse to the Pixer website using the link in the “Resources” section of this article. Click the “Browse” button. Navigate to the location of the photo you would like to convert, and double-click it. Click “Upload & Edit.” The picture appears in the main area of the window.
Select the radio button labeled “Black and White” and click “OK.” Click “Yes” to confirm.
Press the Windows logo and “R” keys simultaneously, and then type “mspaint” in the “Run” dialog box and press “Enter.” Alternatively, select “Paint” from the Start menu.
