Export as SVG for sharp, infinitely scalable graphics and tiny file sizes. PNG/JPG are also available for hero backgrounds, thumbnails, or when raster is preferred.

Yes. SVGs scale perfectly on any screen density. For PNG/JPG, download at 2× and serve with responsive image attributes (srcset/sizes) for crisp results on retina displays.

Absolutely. You can tweak colors in Illustro and further customize the exported SVG in Figma or Illustrator to apply your HEX, HSL, or design tokens exactly.

SVGs are lightweight and render fast. For rasters, use next-gen formats (WebP/AVIF where possible), lazy-load below‑the‑fold media, and define width/height to avoid CLS.

Yes. Illustro grants full commercial rights for assets you generate. You can use them on landing pages, blogs, documentation, marketing sites, and client projects.

Export as SVG (preferred) or PNG with transparency. This lets you place the graphic over gradients, photos, or patterns without visible bounding boxes.

Yes. Open the SVG in Figma/Illustrator to modify shapes, colors, stroke weights, or layout. The structure is clean so you can quickly adapt visuals for each page.

For heroes, 1200–1600px width is common for rasters (serve responsive variants). For icons and spot illustrations, prefer SVG so one asset fits all breakpoints.

Yes. Generate several concepts by tweaking the prompt or palette. Export multiple versions and run A/B tests to see which illustration drives more engagement.
