* It's far more convenient to keep both emails and all attached files in one file type. Our competitors state that they 'process attachments'. However, they just leave them untouched. The reason is that your emails can have numerous file types attached. Office files, CAD drawings, images, presentations, contacts, other emails. It's not an easy task to convert them all. Here at Coolutils we have been developing file converters since 2003, so our engine is powerful enough to cope with over 215 file types. That's why we guarantee that we indeed convert your emails and attachments in the most accurate way.
