Vectorising images is an essential skill for designers, and numerous tools and tutorials are available to help you master this process. Vector images are crucial for high-quality, scalable graphics used in various applications, from billboards to business cards. This guide explores different methods to converting images to vectors format, emphasising tools, techniques, and the historical evolution of vector graphics.
The Evolution of Vector Graphics
The concept of vector graphics dates back to the 1960s, with the development of computer graphics. Early vector displays used cathode-ray tubes (CRTs) and were initially employed in military and aerospace applications. The term “vector graphics” became prominent with the rise of computer-aided design (CAD) software in the 1970s, revolutionising industries by allowing precise, scalable designs.
Adobe Illustrator, introduced in 1987, played a pivotal role in popularising vector graphics among designers. Its powerful tools enabled the creation of intricate, high-resolution artwork, setting the standard for vector graphic design. Over the years, vector graphics have become integral to various fields, from branding to large-scale printing.
Understanding Vector Images
Before diving into the conversion process, it’s important to understand the two basic categories of digital images: raster and vector graphics.
Raster Graphics are commonly seen in file types like .jpg (Joint Photographic Experts Group) and .png (Portable Network Graphics). These images are composed of pixels. When you zoom in on a raster image, it becomes blurry and pixelated.
Vector Graphics, on the other hand, are made up of mathematical formulas that create points, paths, lines, curves, and shapes. This structure allows vector images to be infinitely scalable without losing quality. Common vector file formats include .ai (Adobe Illustrator), .eps (Encapsulated PostScript), and .svg (Scalable Vector Graphic).
Applications of Vector Images
Vector images are widely used in branding and printing. They are ideal for logos, icons, and other graphics on websites, as well as for large-scale prints like banners and small prints like business cards and stickers. Because they are resolution-independent, vector files ensure that even the smallest details remain sharp and clear.
Tools for Converting Images to Vectors
There are various software options, both offline and online, that can export images as vectors. Popular professional tools include Adobe Illustrator and CorelDRAW, while free and open-source alternatives like Inkscape and Vectr are also available. Online conversion tools offer quick solutions but may lack precision and high resolution.
Methods to Convert Images to Vectors
Here are six effective ways to convert flat images into vectors:
1. Hire a Professional Service
One of the simplest ways to convert an image to a vector is to use a professional service like AAC’s graphics team to vectorise for you, for a small fee. This service eliminates the hassle of manual tracing and fine-tuning, delivering high-quality vector images that are ready for any application. AAC’s team guarantees a high-resolution, infinitely scalable vector graphic for a low rate.
2. Manual Conversion in Graphic Design Software
If you prefer to convert images manually, you will need graphic design software such as Adobe Illustrator, CorelDRAW, or Inkscape. Here’s a basic guide:
- Open your image in the chosen software.
- Create a new layer on top of the image.
- Use the pen tool to trace the image, creating paths and shapes.
- Use the color picker to fill in the shapes with the corresponding colors.
- Hide or delete the original raster image.
- Export the new vector image as an .svg file.
3. Convert PDFs to Vectors
Converting PDFs to vectors is often simpler than other formats since PDFs may already contain vector elements:
- Open the PDF in Adobe Illustrator or another vector-compatible software.
- Use the selection tool to highlight the shapes, graphics, and text you want to convert.
- Convert the text to paths by selecting “Create Outlines” from the Type menu.
- Export the file as an .svg.
4. Use Adobe Illustrator’s Image Trace Feature
Adobe Illustrator offers a quick way to convert flat images into vectors using its Image Trace feature:
- Open a new document in Adobe Illustrator and place your image.
- Select the image and go to the Window menu to open the Image Trace panel.
- Choose the appropriate mode (Color, Grays, Threshold) and adjust the settings for paths, corners, and noise to refine the image.
- Click “Expand” under the Object menu to finalise the vector paths.
- Export the vector image as an .svg file.
Simple, clear images with minimal colors work best for conversion. Zoom in closely when manually tracing to ensure accuracy. Use advanced automatic tracing tools if available. For non-designers, professional services like AAC’s graphic design team provide the best results without the need for manual adjustments.
5. Converting Images to Vectors in Photoshop
Although Photoshop is designed for raster images, you can still convert files to a vector format:
Open your image in Photoshop.
Go to File > Export > Export As.
Choose the SVG file type and click export.
Note that this method embeds a raster image in a vector file, which limits scalability.
Free Online Conversion Tools
Several websites offer free vector conversion services, like pngtosvg.com or Adobe’s online converter. These tools can be useful for quick conversions but may produce lower-quality results with imperfect lines and extra shapes.
