We recently ran a survey asking customers how they use the icons from Iconfinder. Here is some data of what they have shared with us.
The majority of customers use icons for websites and apps, followed by presentations, and by digital marketing material.

Here is how some of them described their use of icons in their own words, for each use type:
Use on websites and apps:
“For iconography in game design.”
“When creating websites, I use icons as logo and favicon.”
"Social media website."
“I use them for css ordered or unordered lists."
Use for presentations and other visual material:
“Mostly I use the icons for eLearning modules that we create on medical and scientific subjects. We also use icons in presentations that we create for clients.”
“I put it on a presentation and record the presentation (on google slides) and edit a bit and put on Youtube.”
“To develop infographics; icons instead of bullet points.”
“I use them for labelling, instructions I format, to identify things on my computer.”
Use for marketing material:
“I use icons in my Instagram account in my post to help others to understand easily by those icons.”
“Sometimes our "art department" doesn't provide an icon and I fill in the missing icons with those from Icon Finder. Often, these are prototypes of placeholders that need to look like a finished product until we get the icons that are approved by our clients.”
Use for educational material:
“For student way-finding (to help them navigate online course material ).”
“Mostly for information on corona.”
Use with other tools:
“The SVG are absolutely essential to Filemaker and I have used many from the site.”
“With Notion.”
Use for identifying desktop apps:
“I use a lot of shortcuts (on my Windows desktop screen) to my most visited websites. Such as USAA, American Express, AT&T, and other banking, insurance, etc websites. I use your icons to personalise and differentiate the many shortcuts.”
“To get icons to show on my desktop for shortcuts to apps.”
We hope this feedback helps with understanding customers and their need for icons.
