16 best free icon sets for UI design

There is certainly no shortage of different icon sets on the Internet. Just a quick Google search and you'll find hundreds of icon sets, many of which are open source and 100% free. The problem is that not all icon sets are created equal.

Choosing a good quality icon set can be as time consuming as creating your own custom icons. It is for this reason, TipsMake has compiled the following list of 16 best free icon sets for UI design to help you save your precious time.

1. Untitled UI Icons

1,100+ free essential icons for modern UI design

Untitled UI Icons is a clean, consistent, and neutral icon library created specifically for modern user interface design.

This 100% free icon set includes over 1,100 icons essential for modern user interface design, neatly organized across 19 categories. There are also additional duotone and duocolor styles available at unaitledui.com/icons if you want something a little different.

Untitled UI Icons launched in early June 2022. It was voted #1 product of the Product Hunt of the Week and downloaded over 20,000 times in the first 2 weeks. It is currently the highest ranked icon set on Gumroad and has been retweeted 1,300 times on Twitter. You can use this huge library in as many projects as you like.

2. Feather Icons

Each icon is designed on a 24x24 grid with a focus on simplicity, consistency, and visibility. If you are looking for a lightweight and extensible icon library that will work in almost any project, Feather Icons is a great choice! It's one of the most popular icon sets in the world.

720 free icons on 2 styles (360 icons for each style)

Majesticons is a useful icon set created by Gerrit Halfmann. They include 720 free icons in two styles - Line and Solid.

This icon set is loved for a few reasons. Firstly, they are super minimalistic and consistent, which means they will work well on any type of web design or UI design project. Second, they are clearly created with care by a professional and are easy to customize right in Figma!

If you need more icons in the future, the developer also has an extended icon pack with more than 3,200 vector icons divided into 48 categories (for a fee). It looks great and is done using Figma based on 24px grid system with 2px stroke width.

4. IconScout's Unicons

1,100+ free icons

Unicons is an awesome icon created by the IconScout team. Although the huge icon set of more than 4,500+ Unicons is a paid icon set, the developer has generously released a library of more than 1,100 free icons.

IconScout's free icon set includes over 1,100 carefully crafted icons on a 24px grid with a 1px stroke width. This free icon set is huge, and users especially like how it's streamlined into 27 categories.

5. Heroicons (1.0)

230 free icons

Heroicons v1.0 is an extremely popular and open source icon library created by Steve Shoger, one of the creators of Tailwind CSS.

It includes 230 beautifully crafted and minimalist icons licensed by MIT. Similar to Feather Icons, this icon set won't be the biggest on this list, but is a favorite, as it's neutral and will suit pretty much any project.

Heroicons is also unique in that it includes 2 distinct styles, suitable for many use cases. Outline icons are created with a stroke of 2px thick and designed to display at 24x24px. For smaller use cases like buttons and form elements, this icon set also includes solid icons designed to display at 20x20px.

This attention to detail is what sets Heroicons apart from the hundreds of much larger icon sets not featured on this list.

You can download the icon set as SVG through the developer's website or copy the official Figma Community file.

6. Heroicons (2.0)

292 free icons

After the success of Heroicons v1.0, Steve Shoger released Heroicons 2.0 in August 2022.

The new library has 292 icons that have been completely redrawn from scratch in a new style. Similar to Heroicons 1.0, this icon set includes 2 distinct styles, tailored to each of your use cases. The default outline icons are designed to display at 24x24px and include a new matching block style. For smaller use cases like buttons and form elements, the icon set also includes a smaller mini style designed to display at 20x20px.

One notable difference between versions 1.0 and 2.0 is that the stroke is thinner at 1.5px by default.

Just like Heroicons 1.0, this set is beautifully designed and Steve generously made this icon set 100% free with the MIT license. As mentioned earlier, this new set of Heroicons is not a huge library, but it is extremely high quality and deserves such wide popularity.

You can download the icon set as SVG through the website or copy the official Figma Community file.
