20+ Free Icon Sets & SVG Collections for Web Designers (2025)

2026-06-05·Guides

Key Takeaways

  • You can legally use most free icon sets for commercial projects, but always double-check the license (MIT, CC BY, or custom).
  • SVG icons are resolution-independent and typically smaller than PNGs—use them for modern web projects.
  • Top libraries like Phosphor and Lucide offer 1,000+ icons each, often with multiple styles (line, fill, duotone).
  • Curated collections save hours of searching—I’ve tested each set listed below for quality and consistency.

Why Bother with Curated Icon Sets?

I’ve been designing interfaces for over a decade, and I’ve wasted countless afternoons hunting for the perfect icon. You know the drill: you find a great set, but half the icons are missing, or the license says “non-commercial only.” That’s why I started maintaining my own collection of free, open-source icon libraries. Below are the sets I actually use in client projects, with real numbers and honest opinions.

The Best Free Icon Libraries (2025)

1. Phosphor Icons

  • Count: 1,888 icons (as of Feb 2025)
  • Styles: Thin, light, regular, bold, fill
  • License: MIT (free for anything)
  • Why I like it: Consistent weight across all icons. The duotone variant is great for dashboards. I used it in a SaaS app last year, and the client loved the polish.
  • Download: SVG, PNG, React/Vue components

2. Lucide

  • Count: 1,200+ icons
  • Styles: Only one—clean, minimal line style
  • License: ISC (similar to MIT)
  • Why I like it: Fork of Feather Icons but actively maintained. The line thickness is uniform, which keeps interfaces looking tidy.

3. Tabler Icons

  • Count: 4,900+ icons
  • Styles: Outlined and filled
  • License: MIT
  • Why I like it: Massive set with niche icons (e.g., “hand-click,” “file-export”). The filled variant is perfect for mobile apps.
  • File size: SVG files average 0.8 KB—lighter than most competitors.

4. Material Design Icons (by Google)

  • Count: 5,000+
  • Styles: Outlined, rounded, sharp, filled
  • License: Apache 2.0
  • Why I like it: Industry standard for Android apps. The “sharp” style works well for data-heavy interfaces.
  • Note: Some icons look dated—Google hasn’t refreshed all of them since 2021.

5. Bootstrap Icons

  • Count: 1,900+
  • Styles: Outlined and filled
  • License: MIT
  • Why I like it: Designed to match Bootstrap components. If you’re using Bootstrap for your site, these align perfectly.

Niche Collections Worth Your Time

  • Heroicons: 288 icons by Tailwind CSS team. MIT license. Perfect for utility-focused apps.
  • Feather Icons: The original—now archived, but still solid. 288 icons, MIT.
  • Boxicons: 2,000+ icons with regular, solid, and logo styles. CC BY 4.0 (requires attribution).
  • Font Awesome Free: 1,600+ icons in solid and brand styles. SIL OFL for icons, MIT for code. The pro version has 10,000+.
  • Ionicons: 1,300+ icons by the Ionic framework team. MIT license. Great for mobile-first designs.

How to Choose the Right Icon Set

I’ve made the mistake of mixing icon styles from different libraries—it looks like a garage sale. Here’s my rule of thumb:

  • Line weight: All icons should have the same stroke thickness. Phosphor regular (2px) and Lucide (2px) pair well.
  • Corner radius: Rounded corners (Bootstrap) vs. sharp corners (Material)—pick one and stick to it.
  • License: If you’re building a commercial app, avoid CC BY unless you’re okay with adding an attribution page.

Downloading and Using SVGs

SVG files are just text—open them in a code editor and you can change colors, sizes, or even combine shapes. For example, I once edited a Phosphor icon to add a custom badge by modifying the `` directly. No design software needed.

  • File size: SVG files are 0.5–2 KB on average, compared to 10–50 KB for PNGs.
  • Accessibility: Add `` and `<desc>` tags inside your SVGs for screen readers.</li></ul> <ul><li><strong>Performance</strong>: Inline SVG (embedding directly in HTML) saves HTTP requests. I use it for small icons on landing pages.</li></ul></p><p><h2>Frequently Asked Questions</h2></p><p><strong>1. Can I use these icons in commercial projects like mobile apps or websites?</strong> <p>Yes, most of the libraries listed use MIT, ISC, or Apache 2.0 licenses, which allow commercial use without attribution. The exception is Boxicons (CC BY 4.0)—you must credit the creator unless you buy a license.</p><p><strong>2. What’s the difference between PNG and SVG for icons?</strong></p> <p>SVG is vector-based—scales to any size without losing quality. PNG is raster—looks blurry if enlarged. For web design, use SVG whenever possible. PNG is only useful if you need to support ancient browsers like Internet Explorer 8.</p><p><strong>3. How do I edit an SVG icon if I don’t have design software?</strong></p> <p>Open the SVG file in any text editor (VS Code, Notepad). You can change the `fill` color by editing the attribute in the `<path>` tag. For complex edits, use a free tool like Inkscape or Vectr.</p></p></div></article><script type="application/ld+json">{"@context":"https://schema.org","@type":"Article","headline":"20+ Free Icon Sets & SVG Collections for Web Designers (2025)","description":"Curated list of 20+ open-source icon libraries with SVG and PNG downloads.

Can I use these icons in commercial projects like mobile apps or websites?\u003c/strong\u003e\n\u003cp\u003eYes, most of the libraries listed use MIT, ISC, or Apache 2.0 licenses, which allow commercial use without attribution. The exception is Boxicons (CC BY 4.0)—you must credit the creator unless you buy a license.\u003c/p\u003e\u003cp\u003e\u003cstrong\u003e2. What’s the difference between PNG and SVG for icons?\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eSVG is vector-based—scales to any size without losing quality. PNG is raster—looks blurry if enlarged. For web design, use SVG whenever possible. PNG is only useful if you need to support ancient browsers like Internet Explorer 8.\u003c/p\u003e\u003cp\u003e\u003cstrong\u003e3. How do I edit an SVG icon if I don’t have design software?\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eOpen the SVG file in any text editor (VS Code, Notepad). You can change the `fill` color by editing the attribute in the `\u003cpath\u003e` tag. For complex edits, use a free tool like Inkscape or Vectr.\u003c/p\u003e\u003c/p\u003e"])</script><script>self.__next_f.push([1,"4:[\"$\",\"div\",null,{\"className\":\"max-w-4xl mx-auto px-4 py-12\",\"children\":[[\"$\",\"nav\",null,{\"className\":\"text-sm text-gray-500 mb-6\",\"children\":[[\"$\",\"$Lc\",null,{\"href\":\"/\",\"className\":\"hover:text-gray-300\",\"children\":\"Home\"}],[\"$\",\"span\",null,{\"className\":\"mx-2\",\"children\":\"/\"}],[\"$\",\"$Lc\",null,{\"href\":\"/resources\",\"className\":\"hover:text-gray-300\",\"children\":\"Resources\"}],[\"$\",\"span\",null,{\"className\":\"mx-2\",\"children\":\"/\"}],[\"$\",\"span\",null,{\"className\":\"text-gray-400\",\"children\":\"20+ Free Icon Sets \u0026 SVG Collections for Web Designers (2025)\"}]]}],[\"$\",\"article\",null,{\"className\":\"prose\",\"children\":[[\"$\",\"h1\",null,{\"className\":\"text-3xl font-bold text-white mb-2\",\"children\":\"20+ Free Icon Sets \u0026 SVG Collections for Web Designers (2025)\"}],[\"$\",\"div\",null,{\"className\":\"flex gap-2 text-sm text-gray-500 mb-8\",\"children\":[[\"$\",\"span\",null,{\"children\":\"2026-06-05\"}],[\"$\",\"span\",null,{\"children\":\"·\"}],[\"$\",\"span\",null,{\"children\":\"Guides\"}]]}],[\"$\",\"div\",null,{\"dangerouslySetInnerHTML\":{\"__html\":\"$d\"}}]]}],[\"$\",\"script\",null,{\"type\":\"application/ld+json\",\"dangerouslySetInnerHTML\":{\"__html\":\"{\\\"@context\\\":\\\"https://schema.org\\\",\\\"@type\\\":\\\"Article\\\",\\\"headline\\\":\\\"20+ Free Icon Sets \u0026 SVG Collections for Web Designers (2025)\\\",\\\"description\\\":\\\"Curated list of 20+ open-source icon libraries with SVG and PNG downloads.
