Remove a Background
Replace the background of an image with transparency, for example to focus attention or combine with other images.
Snagit offers multiple ways to remove a background or background color from an image and replace it with transparency.
Tip: Start with a transparent Canvas.
Select Image menu > Canvas Color (Windows) or Change Canvas Color (Mac). Click the canvas color preview, select the transparent (checkerboard) option, and click OK (Windows) or Apply (Mac).
Remove Background Option (Mac)
The Remove Background option on Snagit for Mac automatically removes the background of photos and still images, even when the background is not a solid color.
- Right-click or control+click an image and select the Remove Background option.
- To remove additional details, select the Eraser tool. See Eraser Tool.
This option works best on images where this is a high level of contrast between the subject and the background. It may not preserve fine details on the subject, such as individual whiskers or hairs.
Fill Tool
The Fill tool replaces one color with another color or with transparency. The Fill tool works best when the background you want to remove is a solid color.
- Click the Fill tool in the Snagit Editor toolbar.
Note: If the tool is not visible in the toolbar, click the More dropdown. - In the Properties panel, click the Fill dropdown and select Transparent (checkerboard pattern).
- Click the background of the image to replace the color with transparency.
The Canvas appears under transparent areas.
Tip: Adjust the tolerance for a better result.
If the background is not a solid color, Snagit might fill too little or too much of an area with transparency. Press Ctrl+Z (Windows) or Command+Z (Mac) to undo the previous fill, drag the Tolerance slider to adjust the fill amount, and try again.
For more information, see the Fill Tool.
Invert Selection
The Snap to Object and Invert Selection options allow you to remove the color around irregular shapes.
- Click the Selection tool in the Snagit Editor toolbar.
Note: If the tool is not visible in the toolbar, click the More dropdown. - In the Tool Properties, select the Freehand shape.
- Select the Transparent background fill option.
- Click and drag to draw a selection around a shape or icon you want to preserve in an image.
- Click Snap to Object to bind the selection to the edges of the selected element.
- Right-click (Windows) or Control+click (Mac) and select the Invert Selection option.
- Press Delete to replace the inverted selection with transparency.
The Canvas appears under transparent areas.
For more information, see the Selection Tool.
Magic Wand Tool
The Magic Wand tool makes a selection based on the color where you click. The Magic Wand works best to select and remove backgrounds that are a solid color or have only a slight color gradient.
- Click the Magic Wand tool in the Snagit Editor toolbar.
Note: If the tool is not visible in the toolbar, click the More dropdown. - In the Properties panel, select the Transparent background fill option.
- In the image on the Canvas, click the color you want to remove.
- Adjust the Select slider in the Tool Properties to select more or less color adjacent to your image.
- To include all instances of the selected color(s) in the image, click to enable Global Color Selection in the Tool Properties.
- Press Delete to remove the selection.
The Canvas appears under transparent areas.
For more information, see the Magic Wand Tool.
IMPORTANT
To maintain transparency, save the image to a file format that supports transparency: CUR, GIF, ICO, PNG, TIF, or SNAGX.
