Raster graphics (pixels) shine in photos and rich textures, but blur when scaled. Vector graphics (math) stay razor-sharp at any size-perfect for logos, icons, and print.

Master Illustrator faster: V toggles Selection, A for Direct Selection, P draws Pen paths, Shift+Ctrl/Cmd+O outlines strokes, Ctrl/Cmd+G groups, and Ctrl/Cmd+Z undoes-rapidly.

Build high-converting social graphics with one bold promise, a single focal image, and ruthless contrast. Use brand fonts, mobile-first spacing, and a clear CTA-then A/B test color and copy.

Optimize images by compressing and resizing to display dimensions; prefer WebP/AVIF, add responsive srcset, lazy-load below the fold, and strip metadata to cut bytes and speed rendering.

Digital illustration starts with clean paths: learn the Pen Tool to place anchors, refine Bézier handles, and control curves. Build accurate silhouettes first, then add shading and color with layers.
