工作原理
一种感觉、一份简报或一张参考图 — 简单的语言就够了。
完整字符集在大约一分钟内绘制并组装成可用字体。
在工作室中调整任意字形，然后下载 TTF/OTF/WOFF/WOFF2 或从 CDN 嵌入。
常见问题
什么样的 Logo 效果最好？
干净的字形图片：纯色背景上的字标 PNG 或 JPG，高度至少几百像素。没有字母的图标无法扩展，请包含文字部分。
Logo 里没有的字母会匹配吗？
这正是生成器的用途：它从你现有的字母中学习字重、对比、末端和节奏，再以同样的语言绘制其余字符。不满意的地方可在 Studio 中逐字形修改。
能将字体用于品牌的商业用途吗？
可以 — 商业使用由授权覆盖，包括 Logo、包装、客户项目和产品。若是品牌资产，请将字体设为私有。
如果我还没有 Logo 呢？
那就描述品牌 — 生成器既能从图片也能从一句话出发 — 再用结果设计字标。很多人反其道而行：先有字体，再做 Logo。
我会得到哪些文件格式？
每个字体都导出为 TTF、OTF、WOFF 和 WOFF2，并提供 CDN 托管的 @font-face 链接用于网页嵌入。
Why a logo is only five letters, and why that is a problem
A wordmark is drawn once, by hand, for one word. It is the most carefully made lettering a company owns — and it covers maybe eight characters. Everything else the brand says out loud, from headlines to packaging copy to the app store description, is set in something else entirely.
That gap is usually filled by a licensed family that “goes well with” the mark. It works, but the logo stays an island: the letterforms people see most often are not the ones the brand actually designed. Extending the mark into a working typeface closes the gap in the direction that costs least.
What to upload, and what will not work
- Lettering, not an icon. The model extends letters it can see. A symbol with no text gives it nothing to learn from — upload the wordmark, or the version of the logo that includes the name.
- Flat background, decent size. A PNG or JPG on a plain ground, at least a few hundred pixels tall. Gradients, shadows and photographs of a sign all add noise the outlines have to be cleaned of.
- More letters is better. Four characters define a style loosely; ten define it well. If you have a poster or a packaging shot in the same lettering, that is a better reference than the logo alone.
- Say what the image cannot show. If the mark is all caps, describe how the lowercase should behave. If it is a script, say whether letters should connect. The picture answers half the questions; you answer the rest.
How the missing letters are decided
From the characters you supply, four things are read: stroke weight and how it changes through a curve, the contrast between thick and thin, how strokes end, and the rhythm — how much white sits inside and between letters. Those four carry a style far more than any single letterform does.
The rest of the alphabet, digits and punctuation are then drawn to obey the same four. Where the result guesses wrong — and it will, on a letter your mark never had — that glyph is regenerated or hand-fixed on its own in the Studio.
Keep it private, and use it commercially
A font built from your own mark is a brand asset, so it should not sit in a public catalog. Fonts can be kept private on a paid plan — nobody else finds or downloads them — while you still embed the family on your own site from the CDN.
Commercial use covers exactly the cases a brand needs: logos, packaging, client work and products. And if you do not have a mark yet, the order reverses usefully — describe the brand, generate the family, then draw the wordmark in your own typeface.
