Opus 2 accepts a wide range of file formats but the preference is for text searchable (OCR’d) PDFs as these will be fully indexed the Opus 2 platform. This is so that you can search the content of documents when they have been ingested into Opus 2, although naturally some file types do not naturally convert to PDF and these should remain in their native format. Opus 2 is able to OCR documents on upload but we would advise carrying out the OCR offline first if possible as the Opus 2 OCR will increase the upload time.


The following documents will be automatically converted to a PDF when uploaded:

•            Word - .docx / .doc / .dot / .wbk / .docm / .dotx / .dotm / .docb

•            Powerpoint – pptx / .ppt / .ppts / .potm / .potx / .ppa / .ppam / .pps / .ppsm / .ppsx / .pptm

•            Images - .png / .jpeg / .jpg / .bmp / .tiff / .tif / .gif

•            Plain Text - .txt

•            OpenDocument - .odt

•            Mark up Formats - .html / .htm



Any other document types will be uploaded in their native format and Opus 2 will automatically generate a slip sheet which will prompt the user to download the file to view it. There are not any native file viewers built into Opus 2 so when you download the file you will need to have the necessary software on your device to be able to view the file correctly.


Examples of files that will be hosted as native files on Opus 2 include:

•            Excel - .xlsx / .xls / .xlsm / .xltx / .xltm / .xlsb / .xlt / .xla / .xlam

•            Video - .mpg / .mp3 / .mp4 / .mpeg / .wmv / .avi

•            CAD Drawings - .dwg / .dxf / .dgn / .stl



Best Practise for Uploading Files

You can upload a mixture of files during a single upload - any files that need converting will be queued in the upload manager until they have been processed and will then appear in the documents pages once they have been processed.

We would recommend against upload zip files as you will not be able to utilise any of the composite file types when they have been uploaded, as they will be a single native file, or refer to any of the individual documents. These documents should be extracted from the zip file and uploaded as individual documents.


If you have uploaded a native file but it would also be useful to have a PDF version to annotate, you can save a second copy of the file in PDF format and upload this in addition. We would suggest that the document ID or whatever other identifier you are using is suffixed with an “N” to denote the native, e.g. if you are using the document ID then the PDF would have OPUS00001 assigned to it and the native would be OPUS00001N.
