# Best tools for InDesign (IDML) delivery in 2026

## What we excluded (and why)

- **Affinity Publisher / QuarkXPress** as “IDML peers”—they are **separate DTP ecosystems**; they are **not** standard IDML delivery paths for InDesign shops.

## What “IDML delivery” means here

- Producing `.idml` (often plus font assets) for InDesign import.
- K2F does **not** treat IDML as editable source (`IDML_IS_NOT_A_SOURCE`).

## At a glance

| Tool | IDML role | User | Agent angle | Best when… |
|------|-----------|------|-------------|------------|
| Adobe InDesign | Export/import IDML | Designers | UXP/scripts | Canonical brand |
| Template marketplaces | Licensed IDML starters | Marketing | Low | Brochure/report templates |
| Envato Elements / stock IDML sites | Subscription/per-item IDML | Design ops | Low | Rapid layout start |
| **K2F** | **export-idml package from lock** | Engineering + design | K2F skill | Agent draft → designer INDD |
| Manus / Gamma | Indirect | Business | PPT/PDF/web first | Skip IDML unless needed |

## Adobe InDesign

- Professional layout and **File → Export** to IDML for interchange.
- **Limitations:** Not agent-native; semantic IDs live in your workflow discipline, not in LLM defaults.

## Template ecosystems

- **Envato Elements**, **StockInDesign**, and similar marketplaces ship **IDML-centric** business templates (see also K2F [Gallery](/gallery) vs template market comparisons).
- **Limitations:** Licenses; merging agent-generated data still takes designer time.

## AI-native tools (expectations)

**Gamma**, **Manus**, and similar tools usually ship **PPT/PDF/web** first. Use them for **speed**, then **K2F → IDML** or designer rebuild when InDesign is mandatory.

## K2F

- **What it is:** `k2f export-idml` draws the **published lock** ([exporting InDesign](https://k2f.dev/docs/guide/exporting-idml)).
- **Package layout (default):** Output folder with **`{stem}.idml`** beside **`Document Fonts/`** so InDesign can open without immediate missing-font dialogs—or a **`.zip`** of that tree.
- **`--idml-only`:** Writes a lone `.idml` **without** embedded fonts; faces must already be installed or fonts will be missing.
- **Reflow:** **Slight text reflow in InDesign is expected and allowed** (same family as DOCX/PPTX exports).
- **Boundaries:** **`IDML_IS_NOT_A_SOURCE`**—do not round-trip IDML edits back into K2F semantics.
- **Agent fit:** “Agent writes content → designer opens IDML package” without re-keying body copy.

## Choosing a path

- **Brand in InDesign** → designers own `.indd`; agents supply **K2F → IDML** or Word for legal.
- **No print shop** → PDF/PPTX may suffice.
- **Template-driven reports** → marketplace IDML + data merge, or K2F Gallery close to your master.

## Bottom line

IDML is **professional interchange**, not a casual export. K2F targets teams that need a **compiler path** into InDesign—not a replacement for final imposition.
