This icon is meant to represent a sheet of paper with the top right corner folded over. There are horizontal lines running through the middle of it in various lengths. These are meant to represent the words that are written or typed on the paper.
This is a Page 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 13,300 icons, all in the same style and quality.
