WOFF, TTF Or OTF Font Format ?

This blog rich with fonts. 10 kinds of fonts stand here. But, are you ever think "Which one i choose WOFF, TTF, or OTF Font Format ?" That is what in my mind now.

Let me help you choose the right font format for your blog or website.

  1. TTF ( True Type Font ). TTF is most common format. It working on Mac OS and Microsoft Windows OS. The primary strength of TrueType was originally that it offered font developers a high degree of control over precisely how their fonts are displayed, right down to particular pixels, at various font sizes. With widely varying rendering technologies in use today, pixel-level control is no longer certain in a TrueType font. How About browser support. 
  • Safari  = 3.1 >
  • Chrome = 4.0 >
  • IE = 9.0 > ( Partially Supported )
  • Opera = 10.0 >

2.  OTF ( Open Type Font ). According to TTF and OTF Font Format is same. But see this short description
TTF and OTF are extensions that are used to indicate that the file is a font, which can be used in formatting the documents for printing. TTF stands for TrueType Font, a relatively older font, while OTF stands for OpenType Font, which was based in part on the TrueType standard.

A significant difference between the two is in their capabilities. TTF depends solely on glyph tables that define how each character looks while OTF is able to use glyphs along with CCF (Compact Font Format) tables. The cubic Bezier splines used by CCF allow for fewer points to be used in defining how a character would look compared to the quadratic Bezier splines used by TTF fonts. OTF also adds a few smartfont features, on top of the sfnt structure that is being used by TTF, to add additional language support to the fonts. Although it may not have a very significant effect on your computer, it is also worthy to note that the use of CCF in OTF could lead to file sizes that are significantly smaller, given that no special features are used in the font.

Despite the proven superiority of OTF fonts, especially when using CCF, the use of TTF fonts is still very prolific. It may be taking much longer than expected, but the number of OTF fonts is already on the rise. The reason behind this popularity is the simplicity of making TTF fonts compared to OTF fonts that use CCF. Since there is really no reason to stop using TTF in creating new fonts, most font makers still stick to what they know works, even if it is inferior to the alternative.

There is really no issue for the end user as almost all modern applications that uses fonts are able to work with TTF and OTF files. Users don’t need to choose one over the other as they can be used together in creating documents or printing layouts. Summary:

1. TTF is the file extension for TrueType fonts while OTF is the extension for OpenType fonts.

2. TTF fonts depends solely on a glyph table while OTF fonts can either have glyph tables or CCF

3. TTF font files are often much bigger compared to OTF font files

4. TTF fonts are still so much more popular than OTF fonts

5. TTF fonts are much easier to make compared to OTF fonts

3. WOFF. WOFF is a powerful font format. WOFF font format is compatible with All major browser. I use WOFF font format too. Not Just that, This font format is SEO, better typography for the web. So i recommend you to try this format.
