PDF Annotators Apps and Alternatives

PDF annotators are dedicated software applications that will offer users the possibility to add personalized comments onto their PDF files.

Such comments might take the shape of text markup, sticky notes, textboxes or callouts.

Some of these utilities will also enable users to apply freehand drawings onto the PDFs in order to personalize them or to help explain a situation.

One can also apply lines, polygons, rectangles, arrows, circles, or clouds, while also having the chance of embedding video or audio annotations.

It should also be noted that PDF annotators can also be used to adjust existing comments and to customize them.
