This is an icon representing viewing a file. There is a rectangular piece of paper with a folded over corner in the top-right that makes a triangle. A magnifying glass covers the bottom-right portion of the paper.
This is a View icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,700 icons, all in the same style and quality.
