- Not all images are suitable for tracing in Adobe Illustrator. Photo-realistic images with lots of detail may take a long time to trace, use up a lot of computer processing power, and produce large files. The best images to trace tend to be simpler images with relatively few colors and details, such as logos, cartoon images, and illustrations the best images for tracing. You should also use a high-resolution image.

Adjust the Tracing options. The options in the Tracing Options menu are as follows:^{[2]XResearch source}
- Preview: Click the checkbox next to Preview to see the results of the tracing options you select in real-time.
- Presets: Use the drop-down menu next to "Presets" to select a preset tracing option. This will automatically set all the other tracing options in the menu.
- Mode: This selects the color mode you want to use. Your options are "Black & White," "Greyscale," and "Color". "Black & White" uses only black and white colors. "Greyscale" uses black and white and a variety of shades of grey. "Color" allows you to use different colors.
- Threshold: Threshold is used only in black and white mode. It sets what shade colors are converted to black or white.
- Pallette: This allows you to select a specific color palette to use when converting images to color or greyscale. This option is not available for black and white mode.
- Max Colors: This sets the maximum number of colors or shades of grey that can be used in the image trace.
- Output to swatches: Click the checkbox next to "Output to swatches" if you want to save the colors used in the image trace as swatches that you can use later on.
- Blur: This blurs the original source images before tracing. This can help smooth jagged edges and reduce the number of blemishes. Use this slider bar to select how much blurring you want to use before tracing the image.
- Resample: This option re-samples the original image to a specified resolution before tracing the image. This can help speed up the tracing process but also result in degraded results.
- Fills: Click the checkbox next to "Fills" to create regions filled with color or shades of grey in the tracing results.
- Strokes: Click the checkbox next to "Strokes" to create strokes around the filled regions, which can be used to outline the filled regions.
- Max Stroke Weight: This specifies how large an area in the original images needs to be in order to be converted into a stroke. Areas larger than the specified stroke weight will be converted into fills instead.
- Min Stroke Length: This specifies the minimum length an area of the original image must be in order to be traced as a stroke.
- Path Fitting: This specifies how much distance is allowed between the pixels in the original image and the traced shape. A lower setting creates a tighter path around the pixel image.
- Minimum Area: This specifies the smallest number of pixels in the original image that can be traced.
- Corner Path: This specifies how sharp a corner must be in order to be traced as an anchor point in the trace results.
- Raster: Use the drop-down menu next to "Raster" to specify how the original image is displayed in the trace results.
- Vector: Use the drop-down menu next to "Vector" to specify how the traced image is displayed.
Once you are done adjusting the options in the Tracing Options menu, click Trace to apply the trace results.
You should see a blue bounding box around the image on your artboard. If you do not see a blue bounding box around the image, click the image with the selection tool to select it.

- Some shapes have menus that allow you to adjust the shape attributes, such as the number of sides in a polygon. To open a shape tool menu, select the shape tool and then click once on your artboard.
- You can also use the pathfinder to combine shapes, or cut shapes out of existing shapes. To locate the Pathfinder, click Window in the menu bar at the top and then click Pathfinder. Click two or more overlapping shapes, and then click the option you want to use in the Pathfinder panel.

- Click where you want the line to end to create a straight line.
- Click and drag to create a curved line.
- Click another point to create another line that continues the same curve.
- Click the anchor point to stop drawing or change the direction of a line or curve.
- Click the starting anchor point to complete the shape.

Use the subselection tool to adjust shapes. If you need to make adjustments to a shape, you can do so using the subselection tool. Click the icon that resembles a white mouse cursor in the toolbar to select the subselection tool. Then use the following steps to make adjustments to your shape.
- Click an anchor point on a line to select it.
- Click and drag the handles (bezier curves) to adjust the curve of a line.
- Click and drag an anchor point to move it.

Use the gradient tool to add a color blend. The gradient tool allows you to add a color blend to shapes. You can use gradients to add a metallic sheen to an object, or you can use a gradient blend on a round object to make it look 3D. Use the following steps to add a gradient to a shape
- Select the object you want to add a gradient to.
- Click Window followed by Gradient to open the Gradient menu.
- Use the drop-down menu to select a linear or radial gradient.
- Double-click one of the color stops below the color strip (click below the color strip to add more stops).
- Select a color for the stop from the swatches.
- Repeat for additional stops.
- Click and drag the gradient blend in the sample window to the shape.
- Press G on the keyboard to select the gradient tool.
- Click and drag over the shape to adjust the direction of the gradient blend.

Move objects back and forward. You can have many different objects in a layer overlapping. Sometimes you need to move an object into the foreground or push it back into the background. Use the following steps to move an object back or forward:
- Select an object or shape you want to move.
- Click Object
- Click Arrange.
- Click Bring Foward to move the object forward by one increment.
- Click Bring to Front to move the object all the way to the front of the layer.
- Click Send Backward to move the object backward by one increment.
- Click Send to Back to move the object all the way to the back of the layer.
