Röntgen
543 Free SVG Icons by Sergey Vartanov · CC BY 4.0
Röntgen is a focused small-grid icon set from Sergey Vartanov suited to toolbars, dense tables, compact controls, and admin UI. With around 543 icons, it covers a solid core set of needs and works well when you want a focused library rather than an oversized collection. The smaller-grid approach helps it stay sharp in dense toolbars, compact controls, and information-heavy enterprise layouts.
