Vector graphics are the backbone of modern design. Unlike raster images — like JPEGs and PNGs — that store everything pixel by pixel, vector formats describe shapes mathematically using paths, curves, and anchor points. That means you can scale a vector graphic to any size without losing quality. A logo that looks crisp on a business card? It'll look just as sharp on a billboard.
Three vector formats pretty much run the show, each owning a different corner of the design world. AI (Adobe Illustrator) is the gold standard for professional vector work. SVG is what you reach for when you're building for the web. EPS is the old-timer that still connects print and vector workflows. Here's a breakdown of when you'd actually use each one.
Frequently Asked Questions
Not really. AI is a proprietary format that only Adobe Illustrator can fully edit. You can preview some AI files in PDF viewers because modern AI files use a PDF-based internal structure, but for editing you need Illustrator.
It depends. SVG is better for the web — it works in browsers, can be styled with CSS, and search engines can read it. AI is better for professional design — it preserves layers, effects, brushes, and everything else Illustrator can do. Use AI as your master file and export SVG for the web.
Mostly, yes. EPS was the standard for print vector graphics back in the 90s and 2000s, but Adobe now recommends PDF for print delivery and SVG for web. EPS still hangs on in some legacy print shops, but new projects should use AI or PDF instead.
Technically yes — SVG supports CMYK and high resolutions. But most print shops expect PDF, EPS, or AI files. If you need print output, convert SVG to PDF first.
SVG, no question. It's the only vector format that works natively in every browser. You can embed it directly in HTML, animate it with CSS or JavaScript, and search engines can read the text inside it.
