Vector vs. Raster — What the Heck Is the Difference?

Chances are if you're reading this our art team is asking you for your vector file and it probably sounded like Greek to you. We apologize! This happens everyday- you're not alone. This is meant to be an informative read going over Vector Vs. Raster.

Key take aways

• Vector Files are: .ai, .pdf, .eps, .svg

• Raster Files are: .png, .Jpeg (Most Common)

• Saving a Raster as a vector extension will not make it vector.

• It may be a file you can't open and often gets overlooked as "garbage"

• If you paid a designer this is the file you paid them for

🎯 What is a Raster Image?

• A raster graphic (sometimes called a “bitmap”) is built from a grid of tiny colored squares called pixels.

• Every part of the picture — each shade, shadow, or detail — is stored as data for each pixel.

• Common raster file formats: JPG, PNG, TIFF, BMP, GIF, PSD, etc.

• 
  

Why that matters: Because raster images rely on fixed pixels, they’re “resolution-dependent.” If you try to enlarge a raster file beyond its original size (or don’t use high enough resolution for print), you’ll get blurry edges, visible pixels, or a generally unprofessional look. Since raster images are made of fixed pixels and not separate editable parts, the computer treats the entire graphic as one piece, which is why changing just the text color or one icon usually isn’t quick or clean.

So rasters are usually perfect for photos, web images, or digital graphics that stay around the same size.

🧮 What is a Vector Image?

• A vector graphic doesn’t use pixels. Instead it’s built on mathematical “paths”: points, lines, curves, and shapes defined by geometry.

• Because it’s all math, a vector image can be scaled — bigger, smaller, rotated — as much as you want, and it’ll always stay crisp and clean. No pixelation.

• Common vector file types: .AI, .EPS, .SVG, .PDF (when created as vector), etc.

Why that matters: Vectors are ideal for logos, signage, lettering, wraps — i.e. graphics that could be slapped onto a business card or an 18-wheeler. Because the file is resolution-independent, you don’t have to re-create it for every size. It is the purest form of a logo and has maximum edibility

Why Vector vs Raster Matters for Print

Since we run a wrap shop—and often design things like vehicle wraps, yard signs, decals, business signage, etc.—this isn’t just academic. It affects how sharp and professional the final product looks. Here’s why raster-only files can get you into trouble:

• If you take a raster (pixel-based) image and blow it up to sign or wrap size without starting with enormous resolution, it’ll likely pixelate or look fuzzy.

• Even high-resolution rasters can make your file heavy, hard to email or process — and might still degrade if someone tries to resize incorrectly.

• With vector artwork, you get clean lines and crisp edges no matter how big you go — perfect for bold lettering, logos, flat-color shapes that need to stay sharp.

• Vector paths allow us to create precise cut paths so the plotter can perfectly follow the exact shape of your logo.

When it comes to print, especially large things like wraps and signs, vector files are what keep everything sharp, clean, and professional. Raster images have their place — they’re great for photos and web use — but they just don’t scale the same way for big print. You're now nearly an expert on Vector Vs. Raster! woohoo!
