Free Design Assets, Icons and Fonts for Developers

Free Design Assets, Icons and Fonts for Developers

Free design resources for developers cover four needs: icons, fonts, stock imagery, and illustration. The strongest picks — Font Awesome, Google Fonts, Lucide, Unsplash and unDraw — are free, well-licensed for commercial use, and require no design background to use well.

Updated for 2026. Links and free-tier details change — verify before relying on any resource for a deadline.

Most developers reach for design resources reactively, mid-project, when a button needs an icon or a landing page needs a hero image. This list is organized so you can go straight to the category you need without re-Googling the same search every time.

Every entry below names a real, currently operating resource, grouped by the specific job it does — icons, fonts, photography, illustration, color, or mockups — along with a plain-language note on its commercial-use licensing, since that detail varies more across "free" design resources than most developers expect.

Icon Libraries

Font Awesome — the largest and most established free icon library, with thousands of icons in the free tier and a larger paid Pro tier for extra styles. Best for: projects needing very broad icon coverage across many categories. Licensing: free icons are available under the Font Awesome Free license, which permits commercial use; check the specific license file for attribution requirements on icon fonts versus SVGs.

Heroicons — a smaller, MIT-licensed icon set built by the Tailwind CSS team in outline and solid styles. Best for: Tailwind CSS projects wanting a visually matched icon aesthetic. Licensing: MIT, free for commercial use.

Lucide — a community-maintained, continuously growing fork of the Feather icon set, with a consistent stroke-based style and framework packages for React, Vue and more. Best for: projects wanting a large, consistent icon set with active maintenance. Licensing: MIT, free for commercial use.

Feather Icons — the original simple, elegant stroke-based icon set that Lucide forked from, still maintained with a smaller but very polished core set. Best for: minimalist interfaces that don't need the larger icon count Lucide has grown to. Licensing: MIT, free for commercial use.

Material Symbols / Material Icons (Google) — the icon set built for Google's Material Design system, available in outlined, rounded, and sharp styles with variable weight and fill options. Best for: projects following or visually adjacent to Material Design conventions, or Android-adjacent apps. Licensing: Apache License 2.0, free for commercial use.

Phosphor Icons — a flexible, large icon family available in six weight variants (thin, light, regular, bold, fill, duotone), giving more visual range than most single-weight icon sets. Best for: projects wanting fine-grained control over icon visual weight to match different UI contexts. Licensing: MIT, free for commercial use.

Simple Icons — a free set of SVG icons specifically for popular brands and technology logos (GitHub, Slack, npm, and hundreds more), each following that brand's own official color and shape. Best for: developer tools, changelogs, and integration pages that need to display accurate third-party brand marks. Licensing: CC0 for the icon set itself, though individual brand marks may still be trademarked by their respective owners — check before implying an official partnership.

Iconify — not an icon set itself but a unified access layer exposing over a hundred thousand icons from dozens of free icon sets (including several listed here) through one consistent API and component library. Best for: projects that want to mix icons from multiple free sets without managing several separate packages. Licensing: varies by underlying icon set, shown per-icon in Iconify's browser.

IcoMoon — a free icon library and toolkit that also lets you build a custom icon font or SVG sprite from a mix of its own icons and your own uploaded SVGs. Best for: projects that need a custom-assembled icon subset packaged efficiently for production rather than loading an entire library. Licensing: the base IcoMoon icon set is free for commercial use; check individual premium packs separately.

Fonts

Google Fonts — the largest free, open-license font library, searchable by style and pairing, with easy web-embed and self-host options. Best for: any project needing reliable, commercially-safe typography without a font marketplace purchase. Licensing: mostly SIL Open Font License, free for commercial use, verify per font.

Font Squirrel — a curated collection of free-for-commercial-use fonts, each manually vetted for its license terms before listing. Best for: finding a specific display or handwriting-style font Google Fonts doesn't have. Licensing: varies per font, but every listed font is confirmed free for commercial use by the site's curators.

Fontshare (by Indian Type Foundry) — a smaller, design-forward free font foundry offering higher-production-value typefaces than the average free font site, each with a clear license page. Best for: projects wanting a distinctive, less commonly used typeface than the most popular Google Fonts picks. Licensing: mostly free for commercial use; check each font's individual license page since terms vary more than Google Fonts' blanket open licensing.

Inter — a free, open-source typeface specifically designed for high legibility on computer screens at small sizes, widely used in modern web and app interfaces (including this site's own body font). Best for: UI and body text where screen legibility matters more than display personality. Licensing: SIL Open Font License, free for commercial use.

JetBrains Mono — a free, open-source monospace typeface designed specifically for code, with increased letter spacing and distinct glyphs for commonly confused characters (like 0 and O). Best for: code editors, documentation sites, and any interface displaying code blocks. Licensing: SIL Open Font License, free for commercial use.

Stock Photography and Illustration

Unsplash — a large free stock photo library under the permissive Unsplash License, covering nearly every common use case from tech to nature to people. Best for: landing page heroes, blog headers, and marketing sections. Licensing: free for commercial and non-commercial use, no attribution required (but appreciated).

unDraw — open-source, MIT-licensed flat-style vector illustrations with a built-in recolor tool to match your brand palette before downloading. Best for: SaaS landing pages, onboarding flows, and empty states where photography looks mismatched. Licensing: MIT, free for commercial use.

Pexels — another large free stock photo and video library with a license similar to Unsplash's. Best for: video backgrounds and additional photo variety when Unsplash doesn't have the right shot. Licensing: free for commercial use, no attribution required.

Pixabay — a large library combining free photos, illustrations, and vector graphics under its own permissive content license, similar in spirit to Unsplash and Pexels but with a broader mix of asset types in one place. Best for: projects that want photos, vectors, and simple illustrations from a single source. Licensing: free for commercial use, no attribution required, though certain identifiable people or brand content in some images carries its own restrictions clearly noted per item.

Openverse (by WordPress/Automattic) — a free search engine specifically for openly licensed images and audio, aggregating results from providers like Flickr, Wikimedia Commons, and museum collections with the specific Creative Commons license clearly labeled per result. Best for: finding openly licensed images with a documented, verifiable license trail, useful when attribution accuracy matters (editorial or educational projects especially). Licensing: varies per result — Openverse surfaces the specific Creative Commons or public domain license for each item, and some require attribution while others don't.

Storyset — a library of free, customizable vector illustrations organized by theme and animation style, from the same team behind Freepik. Best for: landing pages wanting animated or highly stylized illustration beyond unDraw's flatter aesthetic. Licensing: free with attribution, or attribution-free with a paid Freepik Premium subscription — check the specific terms shown at download.

Open Peeps (by Pablo Stanley) — a free, hand-drawn illustration library specifically of customizable human figures and avatars, built as a mix-and-match construction kit rather than fixed scenes. Best for: building custom avatar or team-page illustrations without hiring an illustrator. Licensing: free for commercial use under a CC0-style license.

Licensing Quick Reference

Free doesn't always mean the same license terms — this table summarizes what to expect before you build a project's asset pipeline around any single resource.

Treat this table as a starting orientation, not a substitute for reading the actual license page of the specific asset you use — terms do shift, and some individual items within a larger library (a specific font, a specific photo) can carry narrower terms than the platform's general policy.

Color Palette and Mockup Tools

Beyond icons, fonts, and imagery, a few free tools round out a developer's design toolkit for the decisions that come right before implementation.

Coolors — a free color palette generator that lets you lock colors you like and quickly generate harmonious options around them, exportable in formats usable directly in CSS or a design tool. Best for: picking a small, cohesive brand or UI color palette without formal color theory training. Status: free, with a paid tier for extra export formats and team features.

Adobe Color — a free browser-based color wheel and palette tool, including the ability to extract a palette directly from an uploaded image. Best for: building a palette that matches an existing photo or brand asset. Status: free, no Adobe subscription required for the palette tool itself.

Figma Community — thousands of free, community-published design files, UI kits, and mockup templates that can be duplicated into your own free Figma account. Best for: starting a design mockup from an existing free template rather than a blank canvas. Status: free files are clearly marked; some community files are paid.

Shots.so and similar free device-mockup generators — quickly wrap a screenshot in a realistic browser or phone frame for a landing page or app-store listing. Best for: presenting a project screenshot professionally without a full design tool. Status: free tier covers common device frames; some offer paid tiers for extra frame styles.

How to Actually Use This List

Pick one icon set and one font pairing per project and stay consistent rather than mixing multiple icon styles or more than two font families — visual consistency matters more than any single asset's individual quality. For a Tailwind-based project, start with Heroicons or Lucide since both were designed with that aesthetic in mind. For typography, pick a Google Fonts pairing early (one display font, one body font) rather than swapping fonts mid-build.

For imagery, decide upfront whether the project reads better with real photography (Unsplash, Pexels) or flat illustration (unDraw) — most polished SaaS products pick one lane rather than blending both across the same page.

Build a small, reusable asset shortlist rather than re-searching from scratch on every project. Once you've picked a font pairing, an icon set, and an imagery style you like, keep a short note of exactly which resource and license you used, so the next project can start from that decision instead of repeating the same research.

When you need a color palette, generate it before touching layout code, not after. Starting implementation with an undecided or ad hoc color scheme tends to produce inconsistent-looking interfaces where colors were picked one at a time as needed rather than as a coordinated set — tools like Coolors or Adobe Color take minutes and prevent this.

For a portfolio site or demo project specifically, a device mockup from Shots.so or a similar generator around your actual screenshot often reads as more polished in a README or case-study write-up than a bare, un-framed screenshot, since a wrapped frame signals intentional presentation rather than a quick raw capture.

If you're building something that needs to look genuinely branded rather than generic, avoid the temptation to use the single most popular icon set or font pairing purely because it's the default choice in a tutorial. Phosphor Icons' weight variants or Fontshare's less common typefaces can distinguish a project's visual identity from the dozens of other projects using the same default Heroicons-plus-Inter combination.

Checking Licenses Before You Ship

A recurring theme across every category in this list is that "free" carries several genuinely different meanings, and the difference matters most once you actually ship something publicly or commercially. MIT-licensed assets (most modern icon sets, unDraw, Open Peeps) are the safest default: broad permission, minimal obligation, well understood by any developer who reviews your project's dependencies later.

CC0 assets (Simple Icons' base set, Open Peeps) go a step further, explicitly waiving even the technical attribution requirement MIT carries, though watch for the separate trademark caveat on brand-icon sets like Simple Icons — the icon's shape may be CC0 while the brand it represents is still legally protected.

Platform-specific licenses (Unsplash's own license, Pixabay's content license, Font Awesome's Free license) are generally safe for the common developer use cases described in this article but read slightly differently from a standard open-source license, so don't assume MIT-style terms apply just because the resource is free. Attribution-optional resources like Storyset are worth a specific check, since the "free" tier there explicitly requires attribution unless you're on a paid plan — an easy detail to miss if you're used to fully unrestricted MIT assets elsewhere in your stack.

The Four Mistakes

1. Mixing icon styles. Combining Font Awesome's filled icons with Heroicons' outline icons on the same interface reads as visually inconsistent even if each icon individually looks fine.

2. Not checking the specific license before commercial use. Free does not always mean unrestricted — Font Awesome's Pro-only icons, some Font Squirrel fonts with narrower terms, and older stock photo sites with attribution requirements all vary; check each asset's actual license page.

3. Using too many font families. More than two font families on one page (one display, one body) usually looks amateur rather than intentional — resist adding a third "just for one heading."

4. Ignoring self-hosting for fonts. Loading Google Fonts directly from Google's CDN is fine for most projects, but self-hosting the font files can improve load performance and avoid an external network dependency — worth doing once a site's performance budget matters.

5. Assuming a brand's logo icon carries the same license as the icon set hosting it. Simple Icons' CC0 license covers the icon artwork it distributes, not the trademark rights of the company the icon represents — using a brand mark to imply an official partnership or endorsement is a separate legal question from whether the SVG file itself is free to use.

6. Forgetting to check whether an "attribution optional" asset actually is. Some libraries, like Storyset, only waive attribution on a paid tier — assuming every free illustration library works like unDraw's fully free MIT terms can leave an unintended attribution requirement unmet in a shipped product.
