Frequently asked questions
Can I edit an OTF font online?
Yes. Drop the .otf on the page and every glyph opens in a grid in your browser. You can regenerate a letter, draw it by hand, or attach a reference image for that one character.
Do ligatures and stylistic features survive editing?
The OpenType layout tables of the original file are kept, so ligatures, contextual forms and kerning stay in the font. A glyph you redraw keeps its place in those rules.
Can I add a language to an OTF font?
Yes. Pick Cyrillic, Greek, Hebrew, Arabic, Devanagari, CJK or another script, and the missing glyphs are drawn in the style of the letters already in the file. New glyphs are paid from your glyph balance.
What do I get back after editing?
OTF, TTF, WOFF and WOFF2 from the same project. The edited file downloads on the Pro plan and above.
Is OTF better than TTF?
Neither is better in daily use. OTF files often have cubic outlines and richer feature sets, while some older tools and print shops expect TTF. If you are not sure, export both from one project.
Which file formats do I get?
Every font exports as TTF, OTF, WOFF and WOFF2, plus CDN-hosted @font-face URLs for web embedding.
How to edit an OpenType font
- Open the .otf. Drop the file on the page. You see every glyph, the scripts the font covers and its weight.
- Change the glyphs. Regenerate a letter, describe the change in words, draw it by hand, or attach a reference image. Each change touches one character and leaves the rest alone.
- Add scripts and weights. Cover a new language or build a Bold or Thin. The new glyphs follow the style of the file you uploaded.
- Export in the format you need. OTF for design apps, TTF where TrueType is required, WOFF2 for the web.
What makes an OTF file different
An OpenType file with PostScript outlines stores each letter as cubic Bézier curves, the format most type designers draw in. On top of the outlines sit layout tables: kerning, ligatures, small caps, alternates, and the rules that join Arabic letters or stack Devanagari marks.
Those tables are why an OTF is easy to break when you edit it by hand. Here you change glyphs and add scripts, and the layout tables of your file stay in place.
OTF, TTF or WOFF2 after editing
Keep OTF for Adobe apps, Figma and Affinity. Export TTF if a printer, a game engine or an older program asks for TrueType. For a website, export WOFF2: it holds the same font in the smallest file.
