How to convert otf to ttf file
- Fonts
- No ratings yet.
A printer, game engine, legacy application, or older operating system may accept TrueType fonts (.ttf) but reject OpenType fonts (.otf). Converting the file produces a format those systems can install or load; the conversion can also be done on 101convert.com without installing software.
What the OTF format is
OpenType Font (.otf) was developed by Microsoft and Adobe. An OTF file can contain either TrueType outlines or PostScript/CFF outlines, plus tables for kerning, ligatures, alternate glyphs, language-specific shaping, and other OpenType features.
Foundries, type designers, and desktop-publishing applications commonly distribute or create OTF files. Programs such as Adobe InDesign, Adobe Illustrator, FontLab, Glyphs, and FontForge can work with them. Current Windows, macOS, and Linux releases generally install and use OTF fonts directly.
What the TTF format is
TrueType Font (.ttf) normally uses quadratic Bézier curves for glyph outlines and includes tables for metrics, naming, encoding, hinting, and optional OpenType layout features. The .ttf extension is widely accepted by older applications, office software, embedded systems, printers, game engines, and font APIs.
TTF is useful when the target program specifically requires that extension or cannot load CFF/PostScript outlines. It is not automatically smaller or higher quality than OTF; its main benefit is compatibility. The extension alone also does not reveal every technical feature in the file, because TrueType-outline fonts can contain OpenType layout tables.
How to convert the font with FontForge
- Install FontForge and make a backup copy of the original
.otffile. - Open FontForge and choose File → Open, then select the font.
- Check the glyphs, encoding, family name, style, and metrics. Resolve missing references or outline errors before exporting.
- Optionally run Element → Find Problems. Apply only corrections that do not alter the intended outlines, spacing, or metrics.
- Choose File → Generate Fonts, select TrueType as the output format, specify a filename such as
MyFont.ttf, and generate the file. - Install and test the result in the target software. In Windows, right-click the file and choose Install; in macOS, open it with Font Book and choose Install Font.
For repeatable jobs, FontForge also provides scripting. A typical command is:
fontforge -lang=ff -c 'Open($1); Generate($2)' input.otf output.ttf
Check the installed FontForge version before automating conversions because command-line behavior and scripting details can vary.
How to use the built-in converter
On 101convert.com, open the font conversion tool, upload the OTF file, select TTF as the output format, start the conversion, and download the generated file. Do not upload a font if its license or a client agreement prohibits third-party processing.
Quality and compatibility limits
When the source uses CFF/PostScript outlines, conversion replaces cubic Bézier curves with quadratic TrueType curves. This approximation can affect sharp corners, overshoots, small-size rendering, spacing, and hinting. A source OTF that already uses TrueType outlines generally undergoes less geometric change.
Converters may remove or alter ligatures, stylistic sets, variable-font axes, color glyphs, bitmap strikes, naming records, and hinting. Variable fonts can be exported as variable TrueType only when the software explicitly supports that output; otherwise, select and export a static instance. Test the generated file at several sizes and in every target application.
Keep the original OTF as the master file and preserve its copyright and license information. Conversion does not grant permission to modify, embed, or redistribute the font.
