We have found 2 software records in our database eligible for .indb to .pdf file format conversion.
Adobe InDesign natively supports the export of its own documents to PDF format, so it should be the natural choice for INDB to PDF conversion.
Another option would be to find some kind of InDesign viewer and use the 'Print' function to save the document as PDF instead printing on paper. But not many such programs likely exist.
INDB
Files with indb suffix can be mainly found as special, rich printed documents or other publications created in Adobe InDesign print layout design software.
PDF
A pdf file extension is mainly used for Adobe Portable document format, commonly referred to as PDF. All programs that create some sort of documents or projects offer the possibility to export their format to PDF format. A free PDF viewer (Adobe Reader) is available for download from Adobe website.
