OKULAR

Okular is a Universal Document Viewer. Multi-platform, fast and packed with features, Okular allows you to read PDF documents, comics and ePub books, browse images, visualize Markdown documents, and much more.

With Okular’s “Annotation Mode” you can easily add inline and popup notes, highlight and underline text, or even add your own text on the fly. The Selection Mode allows you to copy and paste almost anything from your documents to elsewhere. And, if the text is too small, you can use the “Magnifier Mode”. With Okular’s “Thumbnail Panel”, you can browse graphically the part of the document you were looking for. You can also view and verify digital signatures embedded in PDFs, check if they are still valid, and detect any modifications since the document was signed. You can even sign PDFs yourself.

Okular is open source and always free. Try it as an efficient replacement for your PDF viewer / editor.
