To convert an Adobe InDesign file (.indd) to a version compatible with older software, you must export it as an InDesign Markup Language (IDML) file.

How to downsave an InDesign file to open it in an older version
How to Convert InDesign Files to Older Versions Adobe InDesign is not natively backwards compatible, meaning you cannot directly open an .indd file created in a newer version (like InDesign 2024) in an older version (like CS6 or CC 2022). To bridge this gap, you must convert the file into a format the older software can read. Method 1: The IDML Standard (Most Common)
The most reliable way to "downsave" an InDesign file for any version from CS4 through the current Creative Cloud is to export it as an InDesign Markup Language (IDML) file. Open the file in the newer version of InDesign. Go to File > Export (or use the shortcut Cmd/Ctrl + E). In the format dropdown menu, select InDesign Markup (IDML).
Save the file. You can now open this .idml file in any older version of InDesign (CS4 or later).
Re-save as INDD: Once opened in the older version, go to File > Save As to convert it back into a standard .indd document specific to that version. Method 2: Automatic Conversion (Creative Cloud) While the IDML method works well, it is not perfect
If you are a Creative Cloud subscriber, Adobe offers a "Simple Saveback" service.

Here’s a concise, practical guide to convert an Adobe InDesign file to an older version.

If you are dealing with a legacy workflow that requires InDesign CS4 or earlier, IDML might not work. In those rare cases, you need the INX (InDesign Interchange) format.
How to do it:
Note: Modern versions of InDesign have largely phased this out in favor of IDML. If you don't see this option, or if the recipient is on CS5 or later, stick to Method 1.
Step 1: Open the newer version of Adobe InDesign. (e.g., InDesign 2025)
Step 2: Go to File > Open and select your high-version file.
Step 3: Once the file is loaded, navigate to File > Export.
Step 4: In the "Save as type" (Windows) or "Format" (Mac) dropdown menu, select InDesign Markup Language (IDML) .
Step 5: Name your file and save it. (e.g., MyBrochure_v1.idml)
Step 6: Transfer the .idml file to the computer running the older version of InDesign.
Step 7: In the older version, go to File > Open and select the IDML file. InDesign will automatically convert it to a native .indd file for that version.
