Editing fonts in Lipi.ai Font Studio

Fix individual letters, tune kerning, update the metadata that ships inside your OTF, and export a production-ready font file. Everything runs in your browser; no plugins, no font-editor software.

What Font Studio is for

Fix the broken letters in an AI-generated font without regenerating the whole thing. Most AI-generated fonts land 90% right — the other 10% used to mean starting over.
Edit an existing TTF/OTF you uploaded. Regenerate any glyph, adjust kerning, rename the font for delivery.
Tune kerning between specific letter pairs with a live preview, instead of accepting whatever the model produced.
Update the metadata that ships inside the font binary — family, weight, style, designer attribution, version — so the file installs cleanly in design tools.
Export TTF or OTF with every edit baked into the binary. Works in Figma, Photoshop, Illustrator, the Adobe suite, and Office.

Step-by-step

1

Open Font Studio

There are three ways in, all from the Font Studio landing page:

  • Open a font you generated. Any font from the AI generator, image-to-font, or handwriting flow appears as a card. Click it to open in the editor.
  • Upload a TTF, OTF, WOFF, or WOFF2. Drag any font file in. Studio parses it and you can edit it like any other font — even ones you didn't generate here.
  • Resume an existing session. Studio auto-saves every change to a session. The landing page lists everything you've worked on; pick up exactly where you left off.
Sign-up is required so your sessions persist. Free to open and edit; payment is only required at export time.

The editor layout

Once a font is open, the editor is split into three parts:

  • Glyph grid — every character in the font, alphabet by alphabet. Click any cell to inspect and edit that letter.
  • Live preview — type any text and see it set in the current font. Updates as you edit.
  • Toolbars — Metadata, Kerning, and Export controls along the top. None of them block each other; you can flip between sections without losing work.

Fix a single glyph

This is the headline feature. Click any letter in the grid and the regeneration panel opens with three controls:

  1. Prompt — describe the change in plain language. Examples: "make the descender straighter", "match the geometry of the uppercase letters", "add more weight to the curves".
  2. Reference image — drop a photo, sketch, screenshot, or clean image showing how the letter should look. The model uses it as a hard visual target, not creative inspiration.
  3. Apply to variants toggle — fixing the lowercase o can also refresh ò ó ô ö õ ø in the same pass, keeping accented characters in sync.

Regeneration runs in the background (~15 seconds per glyph) and produces a new version that sits alongside the old one in the version picker. Nothing destructive: if the new version isn't right, switch back with one click. The 174 other characters stay exactly where they were.

Use a reference image for visual matching

Text prompts are surprisingly bad at "match the style of the rest of the font." Reference images solve this directly. Drop in a photo, a screenshot of a similar font, or a quick pen-and-paper sketch of the letter shape.

This is especially useful for fonts generated from your own handwriting — if one glyph went wrong, redraw it on paper, photograph it, upload as reference, and the broken letter falls back into the family in about twenty seconds.

Tune kerning between specific pairs

Open the Kerning toolbar to adjust spacing between specific letter pairs (e.g. AV, To, f'). Drag the slider or type a value; the live preview updates as you go.

Kerning changes save to the session immediately. They ship in the exported font as proper OpenType kern table entries, so they apply automatically in any tool that respects font kerning (which is nearly everything: Figma, the Adobe suite, browsers, Office).

Update the font's metadata

Click the Metadata toolbar to set what gets baked into the OTF binary's name table:

  • Font name — what appears in app font menus
  • Family — groups related fonts together
  • Weight — Light, Regular, Bold, etc.
  • Style — Normal or Italic
  • Designer — credited as the author
  • Description — long-form metadata
  • Version — semantic version string
This is what design tools display in their font picker. Set it well — you won't be able to find the font later if it's called Untitled-1.

Export TTF or OTF

Open the Export toolbar, pick TTF or OTF, and download. Every glyph edit, kerning value, and metadata field is baked into the file. Drop it into Figma, install it on your OS, or hand it to a client.

Edits made in Studio are applied via CFF binary patching at export time — you don't need to re-render the entire font. The export takes a couple of seconds even for fonts with hundreds of edited glyphs.

Export requires a paid license. Buy for Use is a single-font purchase for personal or commercial projects; Full Ownership adds full transfer of rights and removes Lipi.ai branding from the font's embedded metadata. Current pricing is shown on the export modal.

Optional: list it on the marketplace

When exporting, toggle Sell this font on the marketplace to opt in to the Lipi.ai font marketplace. Other users can license your font; you keep 70% of every sale via automatic Stripe payouts, with a $4.99/year listing fee.

The marketplace toggle lives inside the Export panel (visible in the step 7 screenshot above). When enabled, you supply a category, designer attribution, and preview image alongside the export. You can de-list any time from your dashboard. See the Revenue Share guide for the full payout terms.

Tips that catch most people

Reference images beat prompts for "match the style" fixes. A 10-second sketch on paper, photographed and uploaded, produces better results than any text description.
Use the "apply to variants" toggle when fixing a base letter. Fixing the base a and skipping variants means à á â ä ã å still carry the old shape — and that's often the whole problem.
Set metadata before exporting, not after. The file name on disk and the family name inside the binary are different — design tools always show the binary name, regardless of what you rename the file to.
Sessions auto-save; you don't need to. Closing the tab mid-edit is fine. Reopen from the landing page.

Troubleshooting

Glyph regeneration produced a worse result

The new version is non-destructive — open the version picker on that glyph and switch back to the previous one. Then try again with a tighter prompt or a reference image; the model has more to go on with a visual target than with text alone.

Export failed with 'edits could not be applied'

Rare CFF-patching edge case — the font exported as the original (without your edits). Refresh the page, reopen the session, and re-trigger export. If it happens twice, email contact@lipi.ai with the session ID.

Upload says 'Please upload a TTF, OTF, WOFF, or WOFF2'

The file extension matters. Studio currently supports .ttf, .otf, .woff, .woff2. Variable fonts load but only the default instance is editable for now.

The font doesn't look right in Figma after export

Restart Figma desktop after installing the OTF — it caches the local font list on launch. Web Figma picks up new fonts as soon as you upload via "Add to team library." If a specific glyph still looks broken, re-export from Studio; a stale download can lag behind your latest edits.

I can't find the font in my OS font manager

The display name in the OS is the font's Family + Style from Studio's Metadata toolbar, not the file name on disk. Search by the family name you set in Studio.
