Tera Font Converter — Quick User Guide

Architecture & workflow (recommended)

  1. Input ingestion:
    • Detect file type and extract text plus style metadata (fonts, runs, sizes).
    • For PDFs, extract the text map and glyph-to-codepoint mappings.
  2. Encoding detection:
    • Auto-detect legacy encodings where possible; allow user override.
  3. Mapping layer:
    • Apply a mapping table from source encoding/glyph IDs to Unicode code points or target glyph names.
    • Allow chaining: source→intermediate Unicode→target font mapping.
  4. Normalisation & shaping:
    • Apply Unicode normalisation (NFC or NFD) based on language/script needs.
    • For complex scripts, run shaping (Harfbuzz or similar) to test visual outcome.
  5. Styling transfer:
    • Reapply styling to resulting text; convert font-level effects to CSS/RTF/format equivalents.
  6. Output generation:
    • Produce chosen file format(s) with converted text and retained layout as far as format allows.
  7. Validation & QA:
    • Generate side-by-side diffs, render previews, and create a list of unmapped glyphs for manual review.
  8. Logging & mapping export:
    • Store conversion logs and mapping files so conversions are reproducible and auditable.

3. Online Bulk Converters (With Caution)

There are websites that claim to convert large volumes, but true "Tera" scale is rarely possible online due to bandwidth and server limits. Tools like Convertio or CloudConvert offer paid plans for batch processing (usually up to 100 files at a time). These are suitable for small-to-medium batches, but not for an entire font archive.

2. FontForge (Open Source)

For users on a budget, FontForge is a free, open-source editor that includes powerful scripting capabilities. While the GUI is clunky for manual bulk work, its Python scripting interface allows you to write custom scripts to convert 10,000+ fonts overnight. Tera Font Converter

  • Cost: Free.
  • Best for: Developers and tech-savvy users who need automation.
  • Limitation: Steep learning curve; not ideal for one-off conversions.

1. TransType 4 (by FontLab)

  • Best for: Mac/Windows professionals.
  • Capacity: Handles batch conversions of up to 10,000 fonts per session.
  • Why it wins: It is the only converter that retains Variable Font axes during conversion (TTF -> OTF variable).
  • Price: ~$99 USD.

Pros and Cons

3. OTF Core Tools (by Adobe)

  • Best for: Web font engineers.
  • Capacity: Optimized for massive WOFF2 compression.
  • Why it wins: It generates the smallest WOFF2 files on the market (up to 40% smaller than standard converters).
  • Downside: Command line only. No GUI.
