IDMarkz SE — Complete Product Overview & Expanded User Guide (Windows)
IDMarkz SE for Windows is a focused conversion utility from Markzware that reads Adobe InDesign documents (.INDD / .INDT) and writes IDML packages that can be opened and edited by Affinity Publisher, QuarkXPress, older versions of InDesign, and other IDML-aware applications.
At a glance
- Input: Adobe InDesign (.INDD, .INDT)
- Output: IDML — editable in Affinity Publisher, QuarkXPress, older InDesign
- Platform: Windows 10 / Windows 11 (app is 32-bit and uses the .NET Desktop runtime)
- Workflows: Single file handoff, batch conversion, auto-open to target app
Why IDMarkz SE? Key benefits
- Preserve editability: Avoid destructive round-trips through PDF by converting to IDML which preserves structure, text flow and styles.
- Windows-first: Designed to fit easily into Windows production pipelines where Adobe Creative Cloud is not an option.
- Speed & scale: Fast single-file conversions and batch workflows with status reporting make migrations efficient.
- Simple handoff: Auto-open converted IDML in Affinity Publisher or QuarkXPress for immediate editing and proofing.
Feature overview
Fast INDD → IDML export
Drop an InDesign document into IDMarkz SE and it writes a complete IDML package that keeps pages, frames, text, colors, layers and references intact where possible. This is the most reliable way to preserve layout semantics for handoff to other desktop publishing (DTP) tools.
Auto-open to target editors
Configure After Conversion to launch the resulting IDML in Affinity Publisher, QuarkXPress, or a compatible InDesign version to speed up edits and proofs. This optional automation streamlines single-file workflows.
Batch conversion & status reporting
Batch conversions run sequentially and the Status Window reports success and failures so you can easily identify files needing manual attention. For batch jobs, we recommend disabling auto-open.
System & pre-installation checklist
- Windows 10 or Windows 11 (64-bit operating system recommended)
- Minimum 4 GB RAM (8–16 GB recommended for large docs)
- 1 GB free disk space (SSD recommended for performance)
- Microsoft .NET 6 Desktop Runtime (x86) may be required — install prior to running the app if prompted
- Internet connection for activation/registration
User Guide — step-by-step
The following sections are expanded and rewritten from the official IDMarkz SE User Guide. Each functional area includes practical context, step-by-step instructions, troubleshooting, and illustrative screenshots extracted from the official PDF.
1. Downloading, Installation & .NET Runtime
Download the IDMarkz SE installer (.msi) from the "Download Free Trial Now!" button above. Run the installer and accept the Windows UAC prompts. If the app warns that the Microsoft .NET 6 Desktop runtime is missing, download and install the Desktop x86 runtime. Even on modern 64-bit systems, the x86 runtime is required for this 32-bit application.
After installing the runtime, re-launch the installer or application. If you manage many workstations, pre-deploy the .NET runtime through your standard software distribution system to minimize interruptions.
2. Activation & license management
Open the application and enter your License ID and Activation Code in the activation dialog. Copy and paste to avoid typos. If moving the license to another machine, deactivate the original instance via Help → About → Deactivate, then install and activate on the new host.
3. Interface walkthrough & preferences
The user interface is intentionally minimal: drag-and-drop conversion, a few preferences (Create IDML In, If IDML Exists, Create Lo-Res Previews, After Conversion), and the small menu system (File, Window, Help). These controls provide everything necessary to run both single-file and batch conversion workflows.
Key preference meanings
- Create IDML In — location where IDML packages are written.
- If IDML Exists — choose Rename or Overwrite to avoid accidental data loss.
- Create Lo-Res Previews — useful when original assets are missing to provide visual context in the IDML.
- After Conversion — choose Reveal in Explorer, Open in Target App, or nothing. For batch workflows, Reveal is safer.
4. Converting documents (step-by-step)
- Open IDMarkz SE.
- Drag one or more
.INDD or .INDT files into the drop area, or choose File → Open. - Monitor the conversion progress in the Status Window (Window → Show Status Window).
- After conversion, locate results in the output folder or let the app auto-open them in your configured target application.
Recommended pattern: For single-file handoffs set After Conversion → Open in Target App. For multi-file batches set After Conversion → Reveal in File Explorer then do QA and open only the files that need attention.
5. Status Window & diagnosing failures
The Status Window provides a report of conversion attempts. It lists files which converted successfully and those that failed with an error message. Use this view to identify files requiring special handling (encrypted assets, unsupported object types, or missing links).
6. Handling missing fonts and images
Missing fonts: Install required fonts on the machine that will open the IDML to reduce reflow. Missing images: If the INDD contained externally linked images that are unavailable, enable Lo-Res previews to maintain layout context, then relink high-resolution images inside your target editor before final output.
7. Opening the IDML in Affinity Publisher & common fixes
After IDMarkz SE finishes conversion the IDML will open in Affinity Publisher (if set) or another IDML-aware application. Common issues you may need to address after opening: relinking images, replacing missing fonts, adjusting page-size or DPI / unit mismatches, and verifying imported paragraph/character styles.
8. Page-size & DPI troubleshooting
If converted pages appear too small or large, check units and DPI in the target application. Problems often arise when InDesign used Pixels or non-standard units. Convert to Points and set correct DPI (e.g., 300) in Document Setup to normalize sizes.
9. Moving the license between computers
- Open IDMarkz SE on the old machine → Help → About → Deactivate.
- Install IDMarkz SE on the new machine and activate with the same License ID/Activation Code.

Recommended workflows & operational patterns
Single file: fast handoff
- Set Create IDML In → appropriate project folder.
- Set After Conversion → Open IDML in Affinity Publisher.
- Convert the single INDD, open the IDML, relink assets and correct fonts, then export final PDFs from the target app.
Bulk migration: safe and repeatable
- Collect source INDDs and linked assets in mirrored folders per client.
- Set After Conversion → Reveal in File Explorer (disable auto-open).
- Run the batch conversion and review the Status Window for failures.
- Open only the files that require manual editing and relinking in your target editor.
Organizational tip: Use naming conventions that embed client, job and date (e.g., clientA_newsletter_2025-06-30) to make QA and rollback easier.
Best practices checklist
- Maintain an assets folder with all linked images and fonts before conversion.
- Prefer Reveal in Explorer for batches to avoid interruptions caused by target app dialogs.
- Standardize fonts or use font substitution policies to prevent layout reflow.
- Use Lo-Res previews during initial handoffs when high-res images are not necessary for layout review.
- Run a sample conversion and QA before mass migration to estimate post-conversion fixes.
Customer reviews
Allowed Me To Transition To Affinity Publisher
I do freelance work for small-town newspapers and the cost of Creative Cloud was getting me down. Affinity’s apps have fairly good parity for features but can’t read .indd files. Thankfully, IDMarkz SE does, and the converted files are usually indistinguishable from InDesign; any differences seem to be on Affinity’s end. Thank you for enabling a smooth transition!

Herbert J. Kellner — Dec 22, 2021
Recommended As InDesign Opener — While working on the manual for the Job Contender, we found out we could no longer open some older, important InDesign files. Because of a very tight budget, we moved away from Adobe software to more affordable apps. A graphic designer pointed us in the right direction. His recommendation was Markzware, a leading software publisher.
