This is the Maksymalizuj icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
The Expand icon is made up of four arrows, the arrow head is a right angle and the shaft is a straight line. The arrows start around the center of an invisible square and the arrows point to a corner of the invisible square. The arrow heads each make a corner of the invisible square.
