Converting an InDesign file to an older version is not a direct "Save As" process, but it is reliably accomplished using the IDML export/import workflow. Users must accept that some modern features will be lost or altered. For mission-critical documents, always verify the converted file page by page. For frequent cross-version collaboration, maintain a shared IDML workflow or standardize on the oldest version of InDesign used by any team member.

To convert an InDesign file for use in an older version, you must save or export it as an InDesign Markup Language (IDML) file. Because Adobe InDesign files are version-specific, older versions cannot directly open newer .indd files. Standard Conversion (IDML Method)
This is the standard way to "downsave" a file for compatibility with InDesign CS4 or later: Open your document in the newer version of InDesign.
Go to File > Export (or use the shortcut Cmd+E on Mac / Ctrl+E on Windows). In the format dropdown menu, select InDesign Markup (IDML). Click Save.
Open the newly created .idml file in your older version of InDesign. It will open as an "Untitled" document that you should immediately save as a new .indd file. For Even Older Versions (CS3 or earlier)
If you need to go back as far as InDesign CS3, the IDML format will not work.
You must first open the file in CS4 and export it as an InDesign Interchange (INX) file. Advanced & Third-Party Options how to convert indesign file to older version link
Subject: The Time Traveler’s Dilemma: Saving Your InDesign Files for the Past
We’ve all been there. You’re buzzing with creative energy, toggling between Photoshop and InDesign, utilizing the shiniest new features Adobe has dropped in the 2024 update. You save your masterpiece, zip it up, and send it off to a print vendor or a collaborator.
Then, the email arrives: "We can't open this. We're still running InDesign 2021."
Cue the headache.
Converting an Adobe InDesign file (.indd) to an older version isn't as simple as hitting "Save As" and selecting a date from a dropdown menu. Unlike Word documents, InDesign files are not backward compatible. Once a file touches a newer version of the software, it is effectively branded by that version.
However, there is a lifeline. It’s not a button; it’s a file format called IDML (InDesign Markup Language).
Here is the interesting part: Think of the standard .indd file as a frozen block of code specifically arranged for the current year's engine. It’s rigid. IDML, on the other hand, is a universal text-based language. It strips away the engine-specific code and lays your design out in a structured XML format that older versions of InDesign can read and interpret. Converting an InDesign file to an older version
For extremely old InDesign (CS2–CS3):
But IDML is the modern, reliable method for CS4 and later.
Issue 1: "Cannot open IDML – file is corrupt"
Issue 2: Fonts change after conversion
Issue 3: Images are missing
Issue 4: Older version won't open the IDML at all

While IDML is a lifesaver, it is not a perfect time machine. There are rules to time travel:
The Pro Tip: If you want to look like a true industry pro to your print vendor, avoid IDML if possible. Keep your workflow in the "universal standard" for as long as you can. But if you must travel back in time, IDML is the only bridge strong enough to carry your design across the years.
