File format parity
Last reviewed: 2026-10-10 · Last updated: 2026-10-10 · Change: major (first version: every format InDesign 2026 declares, measured against the code) · Target: Adobe InDesign 2026 (21.6)
Every format InDesign 2026 reads or writes, with DesignCraft's support, fidelity and tests. The
InDesign list comes from its bundle's Info.plist (CFBundleDocumentTypes,
UTExportedTypeDeclarations), its import/export filter folder names and its File menus; ours from
the open/place/export filters in apps/designcraft/src/main.rs and the file.* commands.
Overall numbers: target-app-parity.md; open problems: gaps.md.
Dimension score: ~40% ready (estimated), 150–250 h + 20–60 h for INDD integration. The
single largest gap is that .indd can't be opened.
Read/Write: ✓ supported · ~ partial · ✗ missing · — InDesign doesn't either. Weight: what share of an InDesign professional's file traffic the format carries (used for the score below).

Score
Weighted by the Weight column (documents, output and placed tables; resources unweighted), counting ✓ = 1, ~ = 0.5, and IDML at 0.6 until a real-file corpus proves it: ~45% present. Taking fidelity into account (no INDD, IDML unproven, PDF/X-1a and presets missing), ~40% ready for real work (estimated). INDD alone moves this dimension by up to 30 points.
Remaining effort
| Work | Opus 5.5 h |
|---|---|
| INDD import via a clean-room converter (owner decision, #114) | 20–60 |
| IDML real-file corpus, metric, fixes (#193, #338, #339, #340) | 60–100 |
PDF/X-1a and X-3 (transparency flattener), PDF presets and .joboptions, external validator |
40–70 |
| Print path (Windows, PostScript level 3 output or system print APIs) | 25–45 |
| ICML story import, IDMS snippets, INDT templates (once INDD reads) | 15–25 |
| HTML / fixed-layout EPUB with live text | 20–35 |
| JPEG export dialog, SVG export, EPS export | 10–20 |
| Total | 190–355 (150–250 excluding INDD and PostScript output) |
