Up-Shot

In order to choose the right icon pack for your project, you should consider not only what is popular, but what suits your needs best.

It is important to consider how easy it is to get started, what formats are included in the library, and the price when choosing an icon set.

A set of icons will make your interface easier to navigate and interact with, no matter what kind of application you create. It will be easier for users to engage with your application if you use generic icons that are universally recognized.

There's no reason not to include free icons in your project as most icons used for application development are free anyway. Matching the icon pack's style with your application or website is also important when choosing one.

Ensure that you check out the websites of each icon library you intend to use and search for the icons that will be required for your application before choosing an icon library.
