How to convert Raster image into Vector Image In Illustrator

Introduction

This tutorial will guide you through the process of converting a raster image into a vector image using Adobe Illustrator. By utilizing the pen tool, you can achieve a high-quality vectorization that surpasses automatic methods like live trace or image trace. This skill is essential for graphic design, enabling you to create scalable and editable graphics.

Step 1: Prepare Your Raster Image

• Open Adobe Illustrator.
• Import the raster image you want to convert:
  • Go to File > Place.
  • Select your image file (JPEG, PNG, BMP, etc.) and click Place.
• Adjust the image size and position as needed on your artboard.

Step 2: Create a New Layer for Tracing

• In the Layers panel, create a new layer to keep your vector work separate from the raster image.
• Rename the new layer for easy identification (e.g., "Vector Trace").
• Lock the layer with the raster image to prevent accidental modifications:
  • Click on the layer with the raster image and select the lock icon.

Step 3: Select the Pen Tool

• Choose the Pen Tool from the toolbar (or press the shortcut key P).
• Familiarize yourself with the Pen Tool functionalities:
  • Click to create anchor points.
  • Click and drag to create curves.

Step 4: Trace the Image

• Begin tracing the outlines of your image:
  • Start at a clear point on the edge.
  • Click to create straight lines and click and drag for curves.
• Use the following tips for effective tracing:
  • Zoom in for better accuracy (use Ctrl + +).
  • Keep your paths as smooth and clean as possible.
  • Use the Direct Selection Tool (shortcut A) to adjust anchor points and curves as needed.

Step 5: Refine Your Vector Paths

• After tracing all the major outlines, adjust the paths for precision:
  • Select anchor points and use handles to fine-tune curves.
  • Delete unnecessary points by selecting them and pressing the Delete key.
• Ensure all paths connect correctly to form a complete vector shape.

Step 6: Add Color and Details

• Select your vector paths and apply color:
  • Fill the shapes with color using the Color Picker or Swatches panel.
• If applicable, add additional details by creating new shapes with the Pen Tool or other shape tools.

Step 7: Save Your Vector Image

• Once you are satisfied with your vector artwork, save your file:
  • Go to File > Save As.
  • Choose a vector format (e.g., AI, SVG, or EPS).
• Consider exporting for web use:
  • Use File > Export > Export As to save in formats like SVG or PNG.

Conclusion

You have now successfully converted a raster image into a vector image using Adobe Illustrator's pen tool. This method provides superior quality and flexibility for your graphic design projects. Practice tracing different images to enhance your skills, and explore additional Illustrator features to further refine your vector graphics.
