What is a Vector File?

Vector files are types of files that are typically used for design purposes such as illustrations, logos, and other types of graphics that can be scaled up or down without losing any quality.

They do not use pixels, instead, they are composed of mathematical equations that describe both the shape and color of an image. the mathematical equations place lines and shapes on a two-dimensional or three-dimensional grid. This makes them infinitely scalable- meaning they can be sized up or down without losing any quality.

Examples of vector file formats: PDF, EPS, AI, SVG, STL, Asymptote, INDD, DXF, STEP, DWF, SKP, IGES, PS, 3DS, EMF, Collada, FLT, JT, PRC, 3DXML, MB.

When to use

 

Illustrations, logos, print work, posters, banners, signs, vehicle wraps, website graphics, and packaging.

The small file size and scalability of vector graphics make them ideal for digital printing from business cards to billboards. They’re also used in lower thirds for videos, web-based objects, and computer animation rendering 2D or 3D. If you need an image that can be scaled up or down without losing quality, vector files are a good choice. They are also a good option if the file size is a concern, as they are typically much smaller than other types of image files.

When to avoid

 

Avoid using a vector file if you are going to add a raster image to the vector artwork. A raster image will not provide the same scalability as a vector and will appear pixelated or distorted when the overall image is resized.

The main disadvantage of vector files is that they cannot realistically recreate complex images like photographs. Vector files are better suited for logos, illustrations, and flat graphics.

Scalability

 

You can make a vector image as big or tiny as you like without losing quality because vector graphics are highly scalable. This is a huge advantage when you need to resize an image for different purposes, such as for a website banner or a print ad.

Compatibility

 

Vectors are widely compatible with design programs. They can be opened by most design software programs out there, making them super handy for designers and illustrators.

They support both CMYK and RGB color modes.

File size

 

When working with vector files, it is important to be aware of file size. Vector files are made up of mathematical curves, which means they can be scaled to any size without any loss in quality. However, this also means that vector files can be quite large, especially if they contain a lot of detail. For example, a simple logo may only be a few kilobytes in size, but a detailed illustration could easily be several megabytes. When dealing with large vector files, it is important to have enough storage space and processing power available. Otherwise, opening and editing the file could take a long time, and the final image may not look as smooth as it should. Fortunately, there are several ways to reduce the file size of a vector graphic. For example, you can simplify the curves or reduce the number of colors used. By taking some time to optimize your vector files, you can ensure that they will open quickly and look great at any size.

There are a few things to keep in mind when it comes to vector file size. First, the number of objects in the file will affect the file size. Complex graphics with lots of objects will result in a larger file size than simple graphics with fewer objects. Second, the size of the objects in the file will also affect the file size. Larger objects will require more memory to store, and as a result, will result in larger file sizes. Finally, the level of detail in the file will also impact the file size. More detailed graphics will require more memory to store, and as a result, will lead to larger file sizes. In general, it is best to keep vector files small to minimize memory usage and speed up rendering times. However, if you need to create a complex or detailed graphic, you may need to accept a larger file size.

Editing vector files in different applications

 

Adobe Illustrator is one of the most popular vector editing applications available, and for good reason. It’s packed with features that allow you to create complex graphics with ease. However, it’s not the only vector editing application out there. Inkscape is a free and open-source alternative that offers many of the same features as Adobe Illustrator. GIMP does not have a lot of support for vector graphics.

Converting from bitmap or raster

 

Converting a raster or bitmap image into a vector file is not always straightforward, but there are a few methods that can be used to achieve the desired result. One common method is to trace the outline of the image using vector-based software such as Adobe Illustrator. This can be a time-consuming process, but it offers a high degree of control over the final outcome. Another option is to use an autotrace tool, which will automatically create vector paths based on the pixels in the image. These tools can be found in many image editing programs, and they can produce good results with less effort than manual tracing. Regardless of which method you choose, converting pixel-based images into vector files can open up new possibilities for your design work.
