UniquePDF VS Javelin PDF Reader

UniquePDF offers a brand new way to add a watermark to your PDFs with a unique proposition: each recipient of your PDF gets a PDF with a watermark containing their email address. It means that if you want to share a PDF with 10 people, 10 unique PDFs with 10 different watermarks will be created, adding a new layer of security. You can use PDF for free and send up to 50 unique PDFs per month.

Javelin PDF readers provide all the core functionality needed for viewing standard PDF files and PDF files encrypted using our free Drumlin Publisher Digital Rights Management (DRM) software and Service. These readers support internal and external hyperlinks, contents/navigation trees, a range of page display formats, plus document text searching, annotation and markup. Encrypted files are protected against content copying and onwards distribution. They may also have restrictions applied such as whether printing is permitted and whether they expire at some point and can no longer be viewed.
