What's an annotation meaning? The default definition says that annotation is any extra information associated with a particular point in a document or other piece of information. It can be a note that includes a comment or explanation. But we extended this definition. With Annotation software powered by GroupDocs you are allowed not only to leave comments, but also to draw figures and calculate distances, highlight and mark up documents. That's what we call - to annotate. With us you can do it on PDFs, text documents, diagrams, excel sheets, presentations, images and even CAD files. The most popular annotation examples are highlighting, underlying and striking out text, adding watermarks and polylines.
Annotator powered by GroupDocs allows to highlight pdfs documents. Portable document format by Adobe is very popular wordwide. PDF is not easy to modify, but not for us! Using our annotator you can highlight and annotate it in any way. Looking forward, we are going to add more format specific annotation for pdf, such as an ability to add dropdown and checkbox components.
We are open to communication and welcome all kinds of recommendations, suggestions or feedback. This is why we have a forum where anyone can share their experiences and ideas, or leave any comments.
