Adobe Illustrator offers multiple vector export formats, each serving distinct purposes. Vector graphics use mathematical paths for shapes instead of pixels (like JPEGs or PNGs), ensuring infinite scalability without quality loss. Key formats include SVG (Scalable Vector Graphics), ideal for web use; PDF (Portable Document Format), excellent for printing; and EPS (Encapsulated PostScript), a legacy format still used in some print workflows. The "best" format depends entirely on your specific need—web integration vs professional printing vs compatibility with older systems.

For web projects, SVG is highly recommended. Use it for logos, icons, and interactive elements—tools like WordPress or web design platforms like Figma handle SVG seamlessly. For printed materials like brochures, business cards, or large-format posters, choose PDF. It preserves vector paths and CMYK/spot color information reliably. EPS remains useful for specialized printing or compatibility with very old graphic software but is being replaced by PDF.

SVG offers wide browser support and small file sizes but complex designs may require optimization. PDF ensures print fidelity but lacks SVG's direct web interactivity. EPS faces obsolescence; it isn't web-compatible and supports limited transparency. Modern workflows increasingly favor SVG for digital use and PDF for print. Choosing correctly avoids unnecessary rework and maximizes visual quality across applications.
