How to Vectorize an Image in Photoshop: A Complete Step-by-Step Guide
Have you ever tried to blow up a photo or logo only to have it turn into a blurry, pixelated mess? Or struggled to edit a complex graphic in Photoshop? If so, you‘ve run into the limitations of raster, or pixel-based images.
That‘s where vector graphics come in. Unlike raster images, vectors are mathematically defined and infinitely scalable, making them the go-to format for logos, illustrations, and graphics that need to look sharp at any size.
But what if you already have a raster image that you want to convert to a vector? That‘s where vectorization comes in. And while Adobe Illustrator is the industry standard tool for vector graphics, you can actually achieve impressive vectorization results right within Photoshop.
In this ultimate guide, I‘ll take you step-by-step through the process of vectorizing an image in Photoshop, from choosing the right image to preparing it for tracing, vectorizing it with shapes and paths, and finally saving it as a versatile vector file.
Whether you‘re a complete beginner or a seasoned pro looking to brush up your skills, this in-depth tutorial has you covered. I‘ll also be sharing expert tips and insights along the way to help you get the best possible results. Let‘s jump in!
Raster vs. Vector: What‘s the Difference?
First, let‘s break down the key differences between raster and vector images:
Raster images are made up of a rectangular grid of square pixels, each assigned a specific color value. When you zoom in on a raster image, you can see the individual pixels. Common raster file formats include JPEG, PNG, GIF, TIFF, and PSD (Photoshop).
Vector graphics, on the other hand, are comprised of paths (lines and curves) defined by mathematical equations, along with fill colors for shapes. These paths can be scaled infinitely without losing resolution. Popular vector file formats are AI (Illustrator), EPS, SVG, and PDF.
Take a look at how raster and vector graphics behave when scaled up:

This scalability makes vectors the superior choice for any graphics that will need to be resized, like logos, icons, illustrations, signage, or print designs. Vectors also have the advantage of being editable and having smaller file sizes.
Meanwhile, raster is still the standard for digital photos and complex images with many colors, shading, and texture. Cameras and scanners capture images as pixels, as do digital screens.
To further illustrate the differences, here‘s a quick comparison table of raster and vector:
[Table: Raster vs Vector Comparison]| Raster | Vector | |
|---|---|---|
| Image type | Pixel-based bitmap | Mathematical paths |
| Resolution | Fixed, loses quality when scaled | Infinitely scalable |
| Editing | Destructive pixel editing | Non-destructive editing of shapes and paths |
| File size | Larger, increases with dimensions | Typically smaller, independent of dimensions |
| Common uses | Photos, complex images, web graphics | Logos, illustrations, text, print design |
So in summary, vectorizing images allows us to take the best of both worlds – the visual detail of a raster photo with the scalability and editability of vector paths. This makes it an incredibly useful skill to have in your creative toolbox.
