OTF to TTF Converter
Turn OpenType .otf fonts into TrueType .ttf files for the apps, cutting machines, game engines and devices that only accept TTF, with hints added so small text stays crisp.

Your files are removed from our servers 30 minutes after processing.
Removing scripts you don't use can shrink a web font from hundreds of KB to under 30 KB. Keep all characters for fonts you install on a computer.
Paste the text or characters the font must cover, e.g. a logo word or a headline. Everything else is removed.
Hints sharpen small text on Windows screens. Removing them often saves 10–30% on web fonts; auto-hint adds them to fonts that have none.
Leave empty to keep the original. Renaming lets you install the converted font next to the original without a conflict.
E.g. Regular, Bold, Italic. Leave empty to keep the original style name.

Will the TTF work where the OTF did not?
Yes. The outlines are rebuilt as TrueType curves, the kind every TTF-only program expects, and auto-hinting adds the instructions that keep small text sharp on screen.

Why some software wants TTF
Windows and macOS install .otf and .ttf fonts equally well, and most design software handles both. Plenty of other programs do not. Cutting-machine software, embroidery and engraving tools, some game engines and video editors, older office suites, e-readers and embedded devices often list only TrueType in their font import dialog, and an .otf file is simply refused or shows up blank.
The reason is history. TrueType arrived first and became the default font format on both major desktop systems, so tools written for a narrow purpose often support only it. Converting the font gives those tools the format they expect without changing the typeface you chose.
If the font is meant for a website rather than an app, skip TTF and go straight to a web format; WOFF2 is smaller and supported by every current browser.
OTF
OpenType font
A font format Microsoft and Adobe developed in 1996 that extends TrueType. It can hold TrueType or PostScript outlines plus features like ligatures, alternate characters and wide language support. Desktop systems and design software install it directly.

- Open standard
TTF
TrueType font
The outline font format Apple introduced in 1991, later adopted by Microsoft for Windows. Glyphs are described as quadratic curves with detailed hinting for screen display. Every desktop operating system installs it, and it works on the web too, though WOFF2 is lighter there.
- Lossless
- Open standard
Why convertAn OTF usually draws its letters with PostScript curves that TTF-only software cannot read; the TTF redraws them as TrueType curves that every font engine accepts. Convert for a program or device that refuses OTF, and keep the OTF for design work where it already works.
Two flavors of one standard
The confusing part is that OTF and TTF are both OpenType. The OpenType specification, maintained by Microsoft with Adobe, allows a font to store its outlines in one of two ways: TrueType outlines made of quadratic curves, or PostScript outlines made of cubic curves in a table called CFF. Fonts with PostScript outlines normally get the .otf extension, fonts with TrueType outlines the .ttf extension.
Everything else, from the character map to kerning and ligatures, is shared. That is why a conversion keeps the typeface's features: only the outlines and the hints that go with them have to be rebuilt.
Variable fonts, which hold a whole range of weights in one file, are a special case. Their variations depend on the outline flavor too, so check the converted TTF in the program you need before relying on it; if that program cannot use variable fonts at all, a static weight is the safer choice.

Curves, hints and names
Cubic curves cannot always be expressed exactly as quadratic ones, so the converter approximates each curve with one or more TrueType curves, placing the extra points so closely that the difference is invisible at text sizes. The converted file can be slightly larger than the original for the same reason.
Hinting is the other change. PostScript fonts carry their own hints, which TrueType does not use. Without TrueType hints, small text can look soft on Windows screens, so this page starts with Auto-hint, which generates them for the new file. Choose Remove if the font is only for printing or cutting, where hints have no effect, and the file gets smaller.
The internal font names are kept unless you change them. Family name and Style name under Advanced settings rewrite the names stored inside the file, which is what font menus display, so a renamed family appears as a separate entry rather than replacing the original.
Do
- Check the font's license before converting a commercial typeface.
- Give the TTF a new Family name if you will install it next to the OTF.
- Convert every weight of a family together, so Regular, Bold and Italic match.
Avoid
- Converting a font that already works in your program; nothing is gained.
- Uninstalling the original OTF before you have tested the new TTF.
Families, collections and other formats
A typeface usually comes as several files, one per weight and style. Add them all to one batch of up to 20 fonts and each becomes its own TTF with its original style name, so the family stays together when installed. Font collections in .ttc files and older formats such as Type 1 are accepted too; see the Font Converter for every input and output it reads.
For other directions, TrueType fonts can become web fonts with TTF to WOFF2, and a downloaded web font can go back to an installable file with WOFF2 to TTF. Fonts are deleted from the server 30 minutes after conversion and are never shared.
How to convert OTF to TTF
Add the .otf fonts
Drop one or more .otf files on the box above, or press Choose Files. A whole family of weights can go in one batch.
Keep auto-hinting
TTF is selected and Hinting is set to Auto-hint. Under Advanced settings you can rename the family so it installs next to the original.
Convert and install
Press Convert to TTF, download the fonts and install them as you would any other font.
OTF to TTF questions
Is OTF better than TTF?
Neither is better in general. Both are OpenType fonts; they differ in how the letter outlines are drawn. OTF files usually hold PostScript-style curves, TTF files TrueType curves. Convert only when a program you need accepts TTF and not OTF.
Will the converted font look different?
At normal sizes, no. PostScript curves are rebuilt as TrueType curves, which are a slightly different kind of curve, so the shapes are approximated very closely rather than copied exactly. Designers may spot tiny differences at very large sizes.
Do ligatures and alternate letters survive?
Yes. OpenType layout features such as ligatures, kerning, small caps and stylistic alternates live in tables that both flavors share, and they are carried over to the TTF.
Why install the TTF under a different name?
If the OTF and TTF versions share a family name, your system may treat them as duplicates or use the wrong one. Type a new Family name under Advanced settings, such as the original name plus TT, to keep both installed.
Am I allowed to convert a font I bought?
That depends on the font's license. Some licenses allow format conversion for your own use, others forbid modifying the files. Read the license that came with the font before converting it.
Can I convert the TTF to a web font afterwards?
Yes. Use TTF to WOFF2 to make a compressed web font with a ready-made @font-face rule.
