About OTF files

OpenType (.otf) builds on TrueType. Fonts with PostScript-style (CFF) outlines usually use this extension, and the format supports large character sets, alternate glyphs and ligatures.

Open Online loads the font into this tab only. Type your own text, browse the characters and read the font’s details. Nothing is installed.

What you can do here

  • Type your own text and change the size
  • See every character the font contains
  • Read the family, style, version, designer and licence
  • Move sliders for variable fonts (weight, width …)

Limitations

  • The font exists inside this tab only; nothing is installed.
  • WOFF2 files show basic details only, because their data tables are Brotli-compressed.
  • Font collections (.ttc) are not supported.

Privacy

The file is read by your browser and stays on your device. Open Online has no server that could receive it, and nothing is stored once you close the tab. Privacy policy

Common questions

What is the difference to TTF?

Mostly the outline format and some extra typographic features. For previewing, both behave the same.

Are variable fonts supported?

Yes. If the font has variation axes such as weight or width, sliders appear above the preview.
