Guide

The format every logo, icon, and production-ready cut path lives in.

Vector graphics describe images mathematically rather than as pixel grids. That single design choice gives them infinite scalability, tiny file sizes, and the path-quality every production tool needs.

Vector graphics are images defined as mathematical paths — points, curves, and fills — rather than grids of pixels. The math means they scale infinitely without losing quality, store in tiny files (a logo can be 5 KB instead of 5 MB), and produce the closed, clean geometry that vinyl plotters, embroidery digitizers, CNC routers, and screen-print presses all need. Common formats: SVG (web), AI (Illustrator source), EPS (legacy print), PDF (vector inside), DXF (CNC).

What are vector graphics?

Vector graphics are images stored as instructions for how to draw them, not as the drawing itself. A vector logo is a list of points, curve shapes, and fills — together they tell any compatible renderer (your browser, a vinyl plotter, a CNC router) how to reproduce the artwork at any output size.

The opposite is raster graphics, which store the image as a grid of pixels (small coloured squares). Both formats are essential in modern design — they’re tools for different jobs, not alternatives. Photographs are always raster; logos and production-output artwork are almost always vector.

How vector graphics work, briefly

Every vector image is built from a small set of primitives: anchor points, straight or curved segments connecting them (Bézier curves, named after Pierre Bézier who published the math at Renault in 1962), fills (solid colours or gradients), and strokes (outline weights). A logo is typically 10–100 anchor points; a complex illustration might be 1,000–10,000.

When a vector file renders, the software walks the path list and draws each shape at the requested output resolution. The same file rendered at 100 px and 10,000 px produces sharp output at both — the math is recomputed at each size.

Common vector file formats

Vector file formats by use case

Format	Best for	Notes
SVG	Web display, icons, modern cut software	XML-based, embeddable in HTML, styleable with CSS.
AI (Adobe Illustrator)	Editing source	Proprietary but ubiquitous; native to Illustrator.
EPS	Legacy print, sign-shop software, RIPs	Older PostScript dialect; widely supported.
PDF	Print production, customer proofing, document exchange	Can hold vector + raster + type. PDF/X-4 is the print-production subset.
DXF	CNC routing, laser cutting, plasma, waterjet	AutoCAD’s drawing exchange format. R12 or AutoCAD 2000 dialect is most widely supported.
EMF / WMF	Windows-native legacy formats	Mostly historical; SVG has replaced both for new work.

Why production buyers care

Production processes — vinyl plotters, embroidery digitizers, screen-print presses, CNC routers, fiber-laser engravers — all consume vector data, not raster. A sign shop running a Roland plotter feeds it AI or EPS. A laser cutter wants closed-path DXF. An embroidery digitizer wants stitch-friendly vector geometry.

The plotter has no concept of pixels — it moves a blade along the path you give it. If the path is open (start and end points don’t connect), or has hundreds of redundant nodes from a poor auto-trace, the cut comes out wrong. Vector source quality is the rate-limiting step in production workflows.

When to use vector

Logos and brand marks — they live in vector forever.
Icons and UI graphics — SVG icon sets scale infinitely.
Illustrations with flat colour areas, gradients, and clean lines.
Anything heading to a vinyl plotter, embroidery digitizer, CNC, or screen-print press.
Any artwork that needs to print at multiple sizes (business card to billboard).
Cut files for paper crafting (Cricut, Silhouette).
Architectural and engineering drafting.

When vector is the wrong choice

Photographs — raster is the right tool.
Painterly, textured, or impressionistic art that depends on brush-stroke variation.
Screen captures or screenshots.
Anything where you need millions of subtle tone variations (sunsets, skin tones, atmospheric haze).

Tools for working with vector graphics

Adobe Illustrator: Industry-standard editor. $22.99/mo standalone. Job listings still ask for it by name.
Inkscape: Free, open-source. Excellent Pen tool. Best free option for serious vector work.
Affinity Designer: $69.99 one-time. No subscription. Good for designers who want pro-grade tools without recurring cost.
Figma: Free for 3 files, $15/mo Pro. Web-first. Strong for UI/icon work; basic vector editing.
CorelDRAW: $269/yr or $549 perpetual. Strong in sign-shop and wedding-stationery markets.
Vectorizer.AI / vector.ai / Adobe Firefly Vector: AI-driven raster-to-vector converters. $9–25/mo. Use for stylistic conversion or one-shot vectorisation; production-spec work still needs a designer.

Frequently asked questions

Direct answers to what production buyers ask before placing their first order. Question missing? Ask us.

What does ‘vector graphics’ mean in plain English?

Vector graphics are images stored as instructions for how to draw them, rather than as the drawing itself. Think of the difference between a recipe and a finished cake — the recipe (vector) can produce the cake at any size, while the cake (raster) is whatever size it was baked at. That difference is why vector logos can scale infinitely while raster logos pixelate when enlarged.

What’s the most common vector file format?

SVG is the most widely-used vector format today, particularly for web. AI (Adobe Illustrator) is dominant for design source files. EPS is still common in legacy print workflows. PDF holds vector internally and is the standard for print exchange. DXF is the workhorse format for CNC routing and laser cutting.

Are SVG files always vector?

Yes — SVG is a vector format by definition. However, SVG can embed raster images inside it (e.g., a photo placed in an SVG file), so a single SVG can be a mix of vector paths and embedded raster. Most logo and icon SVGs are pure vector.

Can vector graphics represent photographs?

Technically yes, practically no. A faithful vector representation of a photo would need millions of paths and would render slower and look worse than the original raster. AI vectorizers can produce stylised vector interpretations of photos that read as illustrations, but they aren’t a substitute for the original raster image.

Why are vector files so small?

A logo with 50 anchor points stores 50 sets of coordinates and a few colour values — perhaps 5 KB total. The same logo as a 2000×2000 raster image stores 4 million pixels at multiple bytes each — typically 500 KB to 5 MB depending on compression. Vector files trade rendering compute (you have to compute the shapes at output time) for storage efficiency, which is the right tradeoff for most logo-style art.

What’s a Bézier curve?

Bézier curves are the mathematical primitive used to describe smooth shapes in vector graphics. Pierre Bézier published the math at Renault in 1962 for car-body design. Every modern vector editor — Illustrator, Inkscape, Figma — uses Bézier curves under the hood. Most users don’t need to think about the math, but you’ll see the term in tooltips and help docs.

How do I know if a file I’ve been sent is vector?

Open it in Illustrator or Inkscape. If you can select individual shapes as paths, it’s vector. If everything appears as one flat image and zooming reveals pixels, it’s raster. Common extensions are a hint but not definitive — a PDF can be either, an SVG is always vector, a JPG is always raster.

Should I always ask my customer for a vector version of their logo?

If you’re producing the logo on anything physical — vinyl, embroidery, screen print, CNC, signage — yes. If you only need it for digital display at a known size (a single website banner, a single social post), raster is fine. Production work almost always needs vector source eventually.
