Annotations have been used for centuries. Highlighting important parts of the text, jotting down comments or expanding on ideas by writing side notes has been a common practice since people invented written the language.

Whether they are used in education or business, annotations proved to be one of the most useful tools for collaboration.

Many professions have adopted digital annotations. The trend gained traction in the last years, mostly because the ultimate benefit of doing so is saving a lot of time and money.

Editors and publishers, teachers and students, lawyers and clients, journalists and editors-in-chief – they are all using them, and there is no reason for you to be left out.

Tools That Will Make You an Annotating Master

Nevertheless, in order for annotations to prove their worth in today’s collaborative settings, they need to be added to the right digital document format.

Collaborators often use different software for document management, running on various operating systems, with more or less stable internet connections at their disposal.

That is exactly why PDFs are the best canvases for annotating. They are lightweight and cross-platform electronic documents, thus perfect for sharing without any concern if the recipient would be able to handle the file and annotations correctly.
