What is Adobe Illustrator?
Adobe Illustrator is a vector software that uses mathematical shapes to draw on the canvas and therefore the output will always be a vector-based output.
Adobe Illustrator is a professional-grade vector graphics editor developed by Adobe Inc. Released in 1987, it quickly became the standard for creating vector-based artwork, including logos, icons, illustrations, typography and print layouts.
Unlike pixel-based (raster) programs, Illustrator uses mathematical equations and geometric primitives to define shapes, lines and curves, allowing infinite scalability without quality loss.
Fact: Illustrator works primarily with vector graphics, meaning our designs remain crisp and editable at any size—a trait crucial for print production and branding.
What is Vector?
In terms of Physics and Mathematics, Vector is defined as a quantity having a direction as well as magnitude especially as determining the position of one point in space relative to another.
In Graphic Designing, we are dealing with something similar called Vector Graphics which work on the same principle as above.
The Core Philosophy: Vectors
A vector, in design, is an object defined by points, lines and curves—which are described by mathematical equations. Each shape in Illustrator has properties like stroke weight, color, curvature and fill value. These attributes can be changed, transformed or scaled without causing any destructive pixelation.
This property makes Illustrator essential for:
- Logo creation (where designs must be sized from a business card to a billboard)
- Illustrations (especially for print or merchandise)
- Digital typography and font creation
- Technical graphics, charts and infographics
What is Vector Graphics?
Vector Graphics are computer graphics which are defined in terms of 2 dimensional points (or anchor points).
Points (or anchor points) are connected to one another by lines and curves (also known as path or edge) to form various geometrical shapes like rectangle, ellipse (circle or oval) and polygons etc.
All of these points have a definite position on the x-axis and y-axis of the Art Board or Canvas or Work Plane. Hence determines the direction of the path.
These paths may have different properties values such as stroke color, shape, curve, thickness (or stroke weight) and fill.
Most used file formats or extensions for Vector Graphics are SVG, EPS, PDF, CDR or AI.
For commercial purposes, a Vector Graphics may need to be converted into a Raster Graphic file formats like JPEG, PNG etc.
What You Can Create
Illustrator’s toolkit empowers us to design a huge range of visuals, such as:
- Company logos
- Custom typography
- Poster art and banners

Illustrator vs. Photoshop: Fundamental Differences
Assumption check: Many beginners conflate Illustrator and Photoshop or believe they serve identical purposes. This is incorrect and leads to improper use-cases, wasted time and poor output quality.
| Feature | Illustrator (Vector) | Photoshop (Raster/Bitmap) |
|---|---|---|
| Core Data Type | Vectors (mathematical objects) | Pixels (color squares) |
| Output Quality | Infinitely scalable without loss | Degrades if scaled up |
| Use Cases | Logos, icons, illustrations, typography, print | Photo editing, web graphics |
| File Types | AI, SVG, EPS, PDF | PSD, JPEG, PNG, TIFF |
| Editing Approach | Object-based, non-destructive, re-editable | Layer/pixel-based, often destructive |
| Ability to Manipulate | Move, scale, reshape everything easily | Limited to pixels, less flexible |
| Ease of Use | Steep learning curve, less intuitive for photos | Accessible for image editing |
| Layer System | Object stacking, true vector layers | Layer stacking, pixel layers |
| Workplace Integration | Industry standard for print/ layout/ vector branding | Standard for photography/ web |
Fact: Use Illustrator for branded visuals and print design where scalability and clean shapes matter. Photoshop excels for pixel-perfect photo manipulations, retouching and image composites.
| Adobe Illustrator | Adobe Photoshop |
|---|---|
| Adobe Illustrator is a vector-based software application. | Adobe Photoshop is a bitmap or raster-based application. |
| Designs created in Illustrator are Vector Graphic, optimum for prints and web. | Output of Photoshop are always Raster Graphics. Optimum for digital work. |
| A typical vector graphic is something that is drawn using paths. It’s an object-based document and you can scale up as big or small as you want, and it would still maintain the edge fidelity. | In case of Photoshop, you are working with Raster Graphics or bitmap graphics. They can only scale up to a limit. |
| With advancement in web and app technologies, use of Vector Graphics is also increasing. | A lot of standard graphics are created in Photoshop because it’s a very easy tool to use and you can push pixels around. It’s not as constrained and defined by these path-based object. |
| For example: Illustrator ‘Blur’ is kind of a ‘fake blur’ applied to a vector object that re-renders it every time you resize the artwork. | For example: Blur effect in Photoshop is easy to use and reuse. |
| Illustrator is an object-based editing tool, so in Illustrator you have stacks of the object, and the object just has a bunch of attributes attached to it. | As Photoshop is Raster based and support layers, it also has stacking but as it’s Raster, every time we edit it. It gets destroyed. |

Understanding Vector Graphics vs. Raster Graphics
A decisive step in mastering digital design is grasping the difference between vector and raster graphics. Let’s look at an example to further understand Vector and Raster Graphics.
Vector Graphics
- Defined by anchor points, paths, lines, curves
- Edges remain perfectly sharp regardless of scale
- Small file sizes for complex shapes
- Editable at any stage (change color/size/shape instantly)
- Common Formats: SVG, EPS, PDF, AI, CDR
Example: A logo designed in Illustrator can be scaled from a postage stamp to a building without loss of quality.
Raster Graphics
- Comprised of a fixed grid of pixels, each with a color value
- Scaling up leads to blurring and loss of sharpness
- Larger files for high-resolution images
- Best for photographs or complex images
- Common Formats: JPEG, PNG, BMP, PSD, TIFF
Example: A photograph imported into Illustrator becomes a single, uneditable pixel object; attempts to scale or edit it convert the image into blurry, unusable artwork.
Hence, Vector files are recommended for Print purposes and Raster Graphics are good for Digital media.
The whole purpose of working with Adobe Illustrator is to make vector-based illustrations or designs, a common example will be logos. Vector graphics are solely made up of anchor points and lines and there are unlimited ways in which you can alter the artwork according to your requirements.
You can even choose different colors for individual objects on the canvas. Now, on the other hand, if we click on the rasterized image, you will notice that the whole image is just made up of one component.
That means we can’t manipulate the artwork in any way since illustrator works with individual vector-based component and a raster image is treated as a single object.
So, if you are working with an image, there’s little what illustrator can do to manipulate the artwork. On the other hand, there is an infinite number of possibilities when it comes to vector-based artwork.
