Replace a color or transparency in an image by filling the area with a different color.
Use the Fill tool to replace colors in an image to match your brand colors, improve accessibility for viewers, or change the aesthetic.
Note: Fill and other tools in the Snagit Editor toolbar are available to edit images. To edit and enhance video captures, share your video to TechSmith Camtasia.
Note: If the tool is not visible in the toolbar, click the More dropdown. To customize your toolbar, see Customize the Snagit Toolbar.
Tip: Adjust the tolerance for a better result.
If Snagit fills too little or too much of an area on the Canvas, press Ctrl+Z (Windows) or Command+Z (Mac) to undo the previous fill and drag the Tolerance slider to adjust the fill amount.
Edit the properties to customize the tool.
