Frequently Asked Questions about Ilu Library (FAQ)
Can I use these free illustrations in commercial projects or for my startup?
Yes, absolutely. All Ilu illustrations are 100% free for commercial and personal use: websites, startup landing pages, SaaS platforms, mobile apps, pitch decks, and digital products.
In what formats and resolutions can I download the vector graphics?
You can download every asset in clean lossless vector SVG format (ready for web code and Figma), high-resolution transparent PNG from 1x to 4x, high-quality JPG, and scalable vector EPS.
How does the real-time color and stroke customizer work?
When viewing any illustration, our live editor automatically detects its SVG color layers. You can click on any color layer to pick custom brand colors or apply curated palettes, as well as adjust line stroke thickness in real-time before exporting.
Do the illustrations support Dark Mode and Light Mode?
Yes. Because they are clean vector SVGs, you can customize colors for dark or light themes in our live editor, or dynamically control fill and stroke attributes with CSS and Tailwind classes in your frontend codebase.
How do I integrate these vector illustrations in React, Next.js, or HTML?
Simply click the Copy SVG Code button to paste it directly as a JSX component in React or an <svg> element in HTML. Alternatively, download the .svg file and import it using standard <img> tags or bundlers like Vite and Webpack.
Do I need to sign up or provide mandatory attribution?
No signup or subscription required. Attribution is not mandatory, though if you link back to Ilu (carlosdamian.com/ilu), it greatly helps support the project.
Do you design custom illustration sets tailored for brands?
Yes. I design custom vector illustration systems, iconography sets, and UI art direction tailored to your brand identity. You can contact me directly to discuss a bespoke set for your product.
