What is an INDD File?

How to Open, Edit, & Convert INDD Files

A file with the INDD file extension is an InDesign Document file that's most commonly created by and used in Adobe InDesign.

INDD files store page content, formatting information, files, and more. InDesign uses INDD files when producing newspapers, books, brochures, and other professional layouts.

Some InDesign Document files may use just three letters in the file extension, as .IND, but they're still in the same format.

How To Open an INDD File

Adobe InDesign is the primary software used to work with INDD files. However, you can open an INDD file with Adobe InCopy, QuarkXPress (with the ID2Q plugin), and ADOView as well.

You can also sign up for a free trial of WeAllEdit to view and make changes to an INDD file through their website.

How To Convert an INDD File

Using an INDD viewer or editor from above will let you convert the INDD file to another format, but as you'll see below, some conversions require a bit more work.

The most common file type to convert an INDD file to is PDF. Both Adobe InDesign and WeAllEdit can do that.

Also within InDesign, under the File > Export... menu, is the option to export the INDD file to JPG, EPS, EPUB, SWF, FLA, HTML, or XML. You can choose which format to convert the INDD file to by changing the "Save as type" option.

Tip: If converting INDD to JPG, there are some custom options you can pick from like whether to export just a selection or the entire document, as well as change the image quality and resolution.

See Adobe's Export to JPEG format for help understanding the options.

You can also convert the INDD file to a Microsoft Word format like DOC or DOCX, but the formatting differences will likely make the result look a bit off. If you want to do this, you should first export the INDD to PDF (using InDesign), and then plug that PDF into a PDF to Word converter to finish the conversion.

InDesign doesn't have a specific INDD to PPTX export option for using the document with PowerPoint. However, similar to what I explained above for how to use an INDD file with Word, start by exporting the INDD to PDF. Then, open the PDF file with Adobe Acrobat and use Acrobat's File > Save As Other... > Microsoft PowerPoint Presentation menu to save it as a PPTX file.

Tip: If you need the PPTX file to be in a different PowerPoint format like PPT, you can use PowerPoint itself or a free document converter to convert the file.

iXentric SaveBack converts INDD to IDML if you need to use the file in InDesign CS4 and newer. IDML files are ZIP-compressed Adobe InDesign Markup Language files that use XML files to represent the InDesign document.

If you're on a Mac, an INDD file can be converted to PSD for use in Adobe Photoshop. However, you can't do this with InDesign or any of the other programs I mentioned above. See How to Save InDesign Files as Layered Photoshop Files for information on a Mac script that can make this happen.
