About solid icons
Solid icons,
done right.
- Tab & nav active states
- Status & badges
- Small-size UI
- High-contrast themes
Solid icons — sometimes called glyph or filled icons — are built from a single filled shape rather than an outline. With more ink on the page they carry further, stay legible at tiny sizes, and give an interface a confident, tactile feel.
Each Roundicons glyph set is drawn on a consistent grid with matched optical weight so the whole family feels unified. Solid icons pair beautifully with line icons: use line for the default state and solid for the active/selected state in a tab bar.
Delivered as SVG, multi-size PNG, layered AI source and an IconJar archive — recolour to a single brand colour in seconds and ship to any platform.
Where solid icons work best
Built for the places people actually use them.
Active tab states
The filled shape signals the selected item in a bottom tab bar more clearly than any colour change alone.
Tiny UI
At 16px and below, a solid silhouette stays readable where a thin outline would break up.
Status & badges
Notification dots, verified ticks and status pills want a confident filled mark, not a hollow one.
Single-colour branding
Recolour the whole set to one brand colour and you have an instant, unified icon language.

FAQ
Frequently asked questions
What is the difference between solid and line icons?
Line icons use a single outline stroke; solid (glyph) icons are filled shapes. Solid icons read more strongly at small sizes and are often used for active/selected states, while line icons feel lighter for default states.
Are solid icons good for small sizes?
Yes — because they are filled rather than outlined, glyph icons hold their shape and stay legible down to 16px and below, which is why they are popular in mobile tab bars and status indicators.
Can I recolour solid icons?
Absolutely. Each glyph ships as an editable SVG and AI source, so a single fill colour change updates the whole icon to match your brand.
Do solid icons work in dark mode?
Very well. A solid fill set to a light tint reads cleanly on a dark surface, and because each icon is a single shape there are no thin strokes to disappear against the background.
How many solid icons do I get?
It depends on the pack, but our largest solid set runs to several thousand icons across dozens of categories — more than enough to cover an entire product without gaps. The exact count is shown on each pack.
