Vector vs. Raster: What You Need to Know About File Types

Ever been asked for a “vector logo” or wondered why your image looks blurry when printed?
You’re not alone—and you’re in the right place.

Understanding the difference between vector and raster file types is essential for clear, consistent branding. In this post, we’ll break it down in simple terms so you know exactly what’s what and when to use each.
 
What Is a Vector File?
Vector files are made from lines, curves, and points based on math—not pixels. This means they scale infinitely without losing quality.
 
Common Vector File Types:

• .AI (Adobe Illustrator)
• .EPS
• .SVG
• .PDF (if created from a vector program)

Best For: Logos, Icons, Print materials, Embroidery or large format printing, Brand guidelines
 
What Is a Raster File?
Raster files are made up of pixels (tiny squares of color). The more pixels, the higher the resolution—but also the larger the file size.
 
Common Raster File Types:

• .JPG / .JPEG
• .PNG
• .GIF
• .TIFF
• .BMP

Best For: Photos, Web graphics, Social media images, Digital marketing content
 
When to Use Vector vs. Raster:

• Logo on a business card = Vector (.AI, .EPS)
• Facebook post image = Raster (.PNG, .JPG)
• Sending a print ad to a magazine = Vector (.PDF, .EPS)
• Uploading a headshot online = Raster (.JPG, .PNG)
• Designing signage or banners = Vector (.AI, .SVG)

Why Does It Matter?
When you use the wrong file type:

• Your logo may print blurry
• You’ll run into issues with promo products or signage
• Your brand could appear unpolished or inconsistent

 
When you use the right file type:

• Everything looks crisp and professional
• You save time (and money) in the production process
• Your brand visuals stay clear at any size

 
Pro Tip:
If your designer only gives you .PNG or .JPG versions of your logo—ask for the vector files too. You’ll thank yourself later!
