Your sign company asked for a vector file and you're not sure what that means or whether you have one. It's the most common holdup at the start of a sign project.
Short version: a vector file is artwork built from mathematical lines instead of pixels, so it scales to any size without going blurry. Sign fabrication equipment can't run without it. Here's how to tell what you've got and what to do if you don't have one.
Check the file extension on your logo files:
Vector: .ai, .svg, .eps, .pdf
Not vector: .jpg, .jpeg, .png, .gif
If your logo only exists as a PNG or JPG, or you only have it as a social media profile picture or a screenshot, you don't have a vector file. Your original designer almost certainly does, so ask them first.
One catch: a .pdf can contain either vector or raster artwork. A PDF with a JPG pasted inside is still a raster file. If you're unsure, your sign company can tell in seconds.
A raster image (JPG, PNG, GIF) is a grid of colored squares called pixels. A 4K image is about 4,000 pixels wide, and that's all it will ever be. Enlarge it far enough and you see the squares.
A vector image has no pixels. Each line is stored as a mathematical formula describing its shape and position. Because the shape is calculated rather than stored as a fixed grid, you can scale it to any size with no loss of quality. The same file works on a business card and on a 20-foot sign.
Vinyl cutters, laser cutters, CNC routers, and channel letter fabrication equipment all follow paths, not pixels. The machine converts vector lines into a series of points and cuts between them. Hand a cutter a JPG and there's nothing for it to follow.
A logo that looks fine on your website is often a few hundred pixels wide. Blown up to sign scale, a raster file falls apart into visible squares and soft edges. Vector artwork stays sharp at any size.
Need to change a font, adjust spacing, or swap in an updated logo? In a vector file, each element is separate and editable. In a raster file, everything is baked into one flat grid of pixels.
A vector file stores formulas, not millions of pixels, so even large artwork stays easy to email and share.
The most common format in professional design. Viewable in most browsers, but you need Illustrator to edit it.
The most universally useful. It opens in browsers, works with free editing software, and is readable by most fabrication equipment. If you're asking your designer for one format, ask for this.
An older format still in circulation. Works fine for cutting equipment, but doesn't support transparency, which limits some artwork.
Can hold vector or raster content, or both. A PDF exported from Illustrator with live vector artwork is usable. A PDF with a photo pasted in isn't.
This is common, especially for businesses whose logo was made years ago or by someone no longer reachable. Your options:
1. Ask your original designer. They almost always have the source file, even years later. Fastest and free.
2. Have it recreated. Most sign companies, including us, can redraw your logo as a vector file. Simple logos take a couple of hours, complex ones longer. Ask whether it's included or billed separately.
3. Auto-trace it. Software can convert raster to vector automatically, but results are rough on anything but the simplest shapes. Fine for a basic wordmark, not for a detailed logo.
One thing to know: vector converts to raster easily, but raster to vector requires redrawing. So always keep the vector version as your master file.
.ai, .svg, .eps, or a true vector .pdf. JPGs and PNGs can't be used for fabrication.
Not directly. The artwork has to be converted to vector first, either by recreating it or by tracing simple shapes.
Zoom in as far as your PDF viewer allows. If the edges stay crisp, it's vector. If they go blocky, it's a raster image inside a PDF wrapper.
It depends on complexity. Simple wordmarks are usually quick. Detailed or illustrated logos take longer. We'll tell you up front either way.
Free tools can auto-trace, but the results are usually rough. For anything going on a permanent sign, it's worth having it drawn properly.
Send us your logo files and we'll tell you whether they're usable for production — and recreate them if they aren't.
