Make Background Black White in Snapseed: Full Guide

To make the background black and white while keeping the subject in color in Snapseed, use the Selective tool or the Brush tool with the saturation set to zero. The quickest method is to desaturate the entire photo, then use the Brush tool to paint color back onto your subject. This guide walks through both methods, explains when each works best, and answers common questions about the process.

What You Need to Know About Snapseed

Snapseed is a free photo editing app developed by Google, available for Android and iOS. It offers a wide range of tools, from basic adjustments like brightness and contrast to more advanced features like selective editing and healing. The app is widely used for its non-destructive editing workflow, meaning you can always revert to the original image. For the specific task of making a background black and white, Snapseed’s Selective and Brush tools are the most effective options.

Method 1: Using the Selective Tool (Easiest for Simple Backgrounds)

The Selective tool is ideal when the background is fairly uniform, such as a clear sky or a plain wall. It works by placing control points on the image and adjusting the saturation of the area around each point. Here’s how to do it:

1. Open your photo in Snapseed.
2. Tap Tools and select Selective.
3. Tap the + icon to add a control point on the background area you want to desaturate.
4. With the control point selected, swipe up or down to choose the adjustment (you’ll see a list of options like Brightness, Contrast, Saturation). Select Saturation.
5. Swipe left to decrease the saturation to -100. The area around the control point will become black and white.
6. Add more control points on other parts of the background that still have color. Adjust each one to -100 saturation.
7. If the subject also gets desaturated, tap on the control point and adjust its Size (by pinching with two fingers) to reduce the area of influence.
8. Tap the checkmark to apply, then export your image.

This method works best when the background is relatively even in color and the subject is distinct. For more complex backgrounds, the Brush tool offers finer control.

Method 2: Using the Brush Tool (Precise Control)

The Brush tool gives you the ability to paint the effect exactly where you want it. This is the go-to method for portraits or images with intricate backgrounds. The process involves two steps: first, desaturate the whole image, then paint the color back onto the subject.

1. Open your photo in Snapseed.
2. Go to Tools > Brush.
3. At the bottom, select the Saturation brush (the icon looks like a droplet).
4. Set the brush strength to -10 (the maximum negative value).
5. Zoom in and carefully paint over the background areas. The effect will be subtle at first, so you may need to paint over the same area multiple times to fully desaturate it.
6. If you accidentally paint over the subject, switch the brush to +10 (positive) and paint back over the subject to restore its color.
7. Use the Eraser (the icon with a rubber) to fine-tune edges if needed.
8. Tap the checkmark to apply, then export.

This method is more time-consuming but gives you pixel-perfect control. It’s the best choice when the subject has fine details like hair or leaves.

How to Choose Between Selective and Brush

Both tools achieve the same result, but the right choice depends on your image. Use the Selective tool when:

• The background is a single color or gradient (e.g., sky, wall).
• The subject is clearly separated from the background.
• You want a quick edit with minimal effort.

Use the Brush tool when:

• The background has multiple colors or complex patterns.
• The subject has intricate edges (hair, fur, tree branches).
• You need precise control over which parts are desaturated.

For most users, starting with the Selective tool and refining with the Brush tool is a practical workflow.

Common Problems and How to Fix Them

Even with the right technique, you may run into issues. Here are the most common problems and their solutions:

• Subject also becomes black and white: This happens when the control point or brush stroke covers the subject. For the Selective tool, reduce the size of the control point. For the Brush tool, use the eraser or paint with positive saturation to restore color.
• Edges look harsh or unnatural: Use the Brush tool with a lower strength (e.g., -5) and build up the effect gradually. You can also use the View button (the eye icon) to see exactly where you’ve painted.
• Background is not fully desaturated: Make sure you’ve painted over every colored area. Use the Brush tool with multiple passes, and check by zooming in.
• Cannot undo a mistake: Snapseed allows you to undo individual steps by tapping the back arrow. If you’ve already applied, you can go back to the edit history (tap the number next to the image) and re-edit.

Comparison with Other Apps

Snapseed is not the only app that can create a black-and-white background. Here’s how it compares to other popular options:

• Adobe Lightroom Mobile: Offers a similar Brush tool with saturation adjustment, but the free version has limited features. Snapseed is completely free and has no watermarks.
• PicsArt: Has a “Color Splashâ€� effect that does this automatically, but it’s less precise and often requires manual cleanup. Snapseed gives you more control.
• VSCO: Primarily a filter app; it lacks the targeted editing tools needed for this effect.

For a free tool, Snapseed offers a level of control that rivals paid apps, making it a top choice for this specific edit.

Frequently Asked Questions

Can I make the background black and white without affecting the subject?

Yes, by using the Brush tool with negative saturation, you can selectively desaturate only the background. The key is to zoom in and carefully paint around the subject’s edges.

What if the background and subject have similar colors?

If the colors are similar, the Selective tool may not distinguish between them well. In that case, use the Brush tool for manual control. It will take more time, but it will give you the best result.

Can I save the edit as a preset for future photos?

Snapseed does not allow you to save custom presets. However, you can reapply the same steps manually. Alternatively, you can use the “Looks� tab to apply a black-and-white filter, but that will affect the entire image.

Does this work on both Android and iPhone?

Yes, Snapseed is available on both platforms, and the tools work identically. The interface may look slightly different depending on your device’s screen size, but the steps are the same.

Why is my background not turning fully black and white?

This usually happens when you haven’t painted over all colored areas, or the brush strength is too low. Increase the brush strength to -10 and make multiple passes over stubborn areas.

Can I undo the effect after saving?

Once you export the image, the edit is permanent. However, Snapseed saves a copy of the original, and you can always reopen the edited version and continue editing if you haven’t exported it as a new file.
