Designing a monogram favicon that reads at 16 px

A lettermark (one or two initials on a coloured tile) is how Facebook, Notion, Medium and many startups make their icons work at tiny sizes. Full logos and wordmarks turn into blurry smudges in a browser tab.

One letter almost always beats two. If you need two, pick narrow letters and lower the padding so the letters fill more of the tile. Strong contrast between the letter and the background matters more than the exact brand colour, because the icon is often viewed at 16×16.

Rounded tiles (the squircle setting) match iOS and modern Android launchers, so one design works in browser tabs and on phone home screens.

How to use it

  1. 1Type one or two characters into the text input.
  2. 2Pick a high-contrast letter colour and background or gradient.
  3. 3Adjust corner radius and padding while watching the 16 px tab preview.
  4. 4Download the full bundle for web, iOS and Android.

Modern Icon Packages vs. ICO/PNG-Only Converters

Web standards have evolved. A single fixed-size PNG or ICO looks soft on high-density screens and can disappear on dark browser tabs.

Frequently Asked Questions

Can I customize the font and letter colors?

You can set the letter colour, the background colour or gradient, the corner radius and the padding. Letters are drawn in your system's bold sans-serif font so they stay crisp at 16×16.

How many letters should a favicon have?

One is ideal and two is the practical maximum. At 16×16 pixels each letter gets only a few pixels of width, so three or more letters become unreadable.

Can I upload my own logo instead?

Yes. Switch the studio to Upload Logo to use a PNG, JPG, WebP or SVG file. It is processed entirely in your browser.
