If you want to present your documents in a format anyone can read, converting them to PDF (or even an image file like PNG or JPG) is the way to go, particularly if you’re looking to provide a non-editable copy for others to look at (or for you to archive).

These days, outputting files to PDF is pretty straightforward – apps like Microsoft Office let you do so direct from the program itself, while the likes of Nitro Reader let you output any file in PDF format.

But what if you want to convert a large number of Microsoft Office documents – and not necessarily in the same format – quickly? DocuFreezer is your answer – like its sibling, Print Conductor – it’s designed to batch process documents of types quickly and automatically via a drag-and-drop interface.

The main drawback is that DocuFreezer requires Microsoft Office 2010 or later to be installed in order to utilise its APIs to perform the document conversion. If you’re simply looking to convert PDFs to an image format – JPG, TIF or PNG – then everything you need is included.

Launch DocuFreezer and it supplies a single window with all the options you need: you can drag files directly on to the program window or manually select files or a folder of files to process. Pick your destination format from the drop-down menu, and click the Settings button to fine-tune each format’s settings. In the case of PDF, choose PDF-A to omit features ill-suited to long-term archiving, such as linking (rather than embedding) fonts.

Finally, choose an output folder, click Start and let DocuFreezer do the rest. It’s not particularly quick, but it’s fully automated and once done your converted documents will be ready to distribute. There are a few clunky moments – you can’t create a new folder when selecting the destination for example – but if you’re looking for a tool to automate a repetitive process, DocuFreezer is worth checking out.

Note this is free for personal use only – commercial licenses cost $19 per license.

A handy tool for quickly converting documents to PDF or image, but the requirement for Office 2010 limits its appeal.
