These color Participating icons belong to our Flat Colors icon set. This is our second most popular icon pack after iOS. Feel free to download this icon in PNG format for free, or unlock vectors. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 9,000 icons, all in the same style and quality. Like all our free icon packs, these Participating icons are available for download as PNG, SVG, PDF and other vectors, as an icon font, and as HTML/CSS snippets.
Apple introduced the glyph icons in iOS 11 and uses them for tab bar (along with regular iOS icons that are for everything else). The grid is 30×30 pixels. Unlike original iOS icons which are the outline ones, these icons consist of the the filled shapes and visually dense. If you're creating an iOS app, either download Participating PNG icons in 3 sizes (free icons for 50 and 100px; for folks who paid there's 150px) or download a single vector icon in PDF format (you'll have to buy icons) — Xcode will generate the proper PNGs on the compilation.
