Native preview
Review inputs and build; variable fonts require a selected file.
Processing model and limits
Real CSS writing-mode/text-orientation preview, no HTML execution. Three writing modes × three orientations; height160–900px/line-height1–3. Container scrolls independently and preserves newlines. Glyph rotation, shaping and script support depend on local system fonts/browser; no font URL or sensor permissions. Text stays in memory; 32 KiB per field and 1 MiB complete output. Native preview is scoped to its container; exported HTML is escaped text, never injected into the document. Editing cancels pending work and clears stale results.
How to use this tool
Edit the source fields, build the preview, then inspect and export the complete text. For fonts, explicitly select a local file; no external font URL is requested.
