Vector file formats — which one does your production process need? SVG, EPS, AI, PDF, DXF — five formats, five different jobs.

The short version

Every vector format stores the same kind of thing — paths, points, curves, and fills described as math rather than pixels. They differ in who can open them, what extra data they carry (layers, colour profiles, fonts, tool paths), and which downstream machine or press expects them. Pick by destination, not by habit.

Format vs use-case — the quick map

SVG — Scalable Vector Graphics

SVG is an open, XML-based, text-readable vector format and the native vector language of the web. Every modern browser renders it directly, it animates with CSS or JavaScript, and for flat logos and icons it is often 10–100× smaller than the equivalent PNG. Modern cutting software (Cricut Design Space, Silhouette Studio, many laser tools) treats SVG as a first-class input.

• Reach for it when: the artwork goes on a website, an app, or into hobby/prosumer cutting software.
• Strengths: open standard, human-readable, infinitely scalable, animatable, tiny for flat art.
• Watch out for: weak CMYK / spot-colour support (SVG is an RGB-first format), and inconsistent handling of embedded fonts — convert text to outlines before sending.

EPS — Encapsulated PostScript

EPS is the long-standing interchange format for print and sign production. It is PostScript wrapped so it can be placed inside another document, and almost every professional design and sign application can open or import it. For decades it has been the safe lowest-common-denominator file to hand a vendor whose software you do not know.

• Reach for it when: a sign shop, screen printer, or print vendor asks for vector and you are not sure what they run.
• Strengths: near-universal vendor support, carries CMYK and spot colours, reliable for cut paths.
• Watch out for: it is an older container — it does not preserve layers or live editability the way a native AI file does. Keep an AI master and export EPS as a delivery copy.

AI — Adobe Illustrator

AI is Adobe Illustrator’s native format and the de-facto master format for professional vector work. It preserves layers, editable type, swatches, spot colours, and effects. Most production studios keep the AI file as the source of truth and export EPS, PDF, SVG, or DXF from it on demand.

• Reach for it when: it is your working master, or the vendor explicitly runs Illustrator.
• Strengths: full layer and editability, rich colour handling, the cleanest source to re-export every other format from.
• Watch out for: it is proprietary — not every shop can open the latest AI version. When in doubt, also send a PDF or EPS, and outline your fonts in the delivery copy.

PDF — Portable Document Format

PDF is a container that can hold vector paths, raster images, fonts, and a colour profile all at once. A PDF exported from Illustrator is vector inside and prints crisp at any size; a PDF that is a scan is raster inside and will not. For commercial print, the PDF/X family (PDF/X-1a, PDF/X-4) is the standard hand-off because it bundles everything the press needs and locks the colour intent.

• Reach for it when: handing finished artwork to a commercial printer (use PDF/X), or sending a safe view-anywhere proof.
• Strengths: holds vector + raster + fonts + colour profile; PDF/X is a true print standard.
• Watch out for: ambiguity (vector vs raster inside) and the fact that a generic PDF is not the easiest file to re-edit.

DXF — Drawing Exchange Format

DXF is AutoCAD’s interchange format and the language of machine tooling. CNC routers, laser cutters, plasma tables, and engravers read DXF tool paths through their CAM software. It is unit-aware and layer-aware, so cut, score, and engrave operations can live on separate layers. For any process that drives a physical cutting head, DXF is usually the file the machine actually wants.

• Reach for it when: the artwork drives a CNC router, laser, plasma table, or engraver.
• Strengths: native to CAM workflows, unit-aware, layer-aware for cut/score/engrave separation.
• Watch out for: dialect and unit mismatches. Many shops want a specific DXF version (AutoCAD 2000 / R12 is a common safe target) and explicit units (mm vs inch). Confirm both, and make sure every path is closed.

Deciding for a real job

I run a vinyl plotter

EPS or AI with closed cut paths. SVG or DXF also work in many sign apps — confirm with the shop.

I’m screen printing a multi-colour design

AI or EPS so spot-colour separations and overprint survive. Outline the type before sending.

I’m handing a logo to an embroidery digitizer

AI or EPS with clean joins and no stray nodes. Hand-rebuilt vector beats auto-traced for stitch quality.

I’m CNC routing or plasma cutting

DXF, closed paths, in the version and units the CAM software expects (often AutoCAD 2000 dialect, mm).

I’m laser cutting and engraving

DXF or SVG with cut, score, and engrave on separate layers or colours so the laser maps each operation.

I’m sending artwork to a commercial printer

PDF/X with fonts embedded and the correct ICC profile. Keep your editable AI master in case of changes.

I’m putting a logo on a website

SVG — native to browsers, scalable, animatable, and tiny for flat-colour art.
