You might not want to scroll through the icons and vectors listed on the Flaticon website; there are just under 700,000 of them to date. Luckily, they are split into a large number of ‘packs’ which makes things much easier! You will have to provide author attribution for free icons unless you pay for premium membership. Subscription fees are low, however, and once an icon has been bought no author attribution is required even after the subscription is cancelled. All icons and vectors are available in PNG, SVG, EPS, PSD and BASE64 formats.
