Note that some of these image formats are “lossy” (for example, JPEG). Reducing file sizes for lossy formats may result in a degradation of image quality and accuracy of results from Konfuzio.
File extension handling & correction#
It is possible to upload files with no (unknown or corrupted) file extension to Konfuzio (e.g. instead of
file:example.pdf, file: example.p, example, or evenexample.example.example was uploaded) when this happens,
internally correction logic is run in order to try and guess the correct extension before saving and or extracting
the file/document. This correction attempts to guess all supported file types, but success cannot be guaranteed. The
maximum file extension for this correction to work should not exceed 99 characters.
PDFs#
Konfuzio supports PDF/A-1a, PDF/A-1b, PDF/A-2a, PDF/A-2b, PDF/A-3a, PDF/A-3b, PDF/X-1a, PDF/1.7, PDF/2.0. An attempt will be made to repair corrupted PDFs. Konfuzio does not support AcroForms and AEM (Adobe Experience Manager) form content.
Images#
Konfuzio supports JPEG, TIFF and PNG (including support for alpha channel).
Office documents#
Konfuzio offers limited support for common office documents like Microsoft® Word (.doc, .docx), Excel (.xls, .xlsx), PowerPoint (.ppt, .pptx) and Publisher as well as the Open Document Format (ODF). Uploaded office documents are converted to PDFs by Konfuzio. Libre Office is used for the PDF conversion. The layout of the converted office document may differ from the original. Office files can not be edited after they have been uploaded.
