Editing PDFs is something many people need to do, but unfortunately it’s not always the easiest thing to manage. The format is not designed to be easily edited, and despite a plethora of Windows and web apps, there is no universal solution beyond Adobe’s expensive Acrobat Pro.
LABELING PDFS
Labeling is probably the most common way to edit PDFs. Many times when sharing a PDF file with someone else, you may need to draw attention to something by crossing it out with a “marker,” adding a comment, or drawing something in the document.
This type of editing is included in many PDF programs that do not have other forms of editing. Both Adobe’s otherwise very limited Acrobat Reader DC and popular third-party applications like Foxit and Sumatra PDF support labeling and annotation. Full-fledged editors like PDFgear, PDF-Xchange, and Adobe Acrobat Pro also have it, but so does the built-in PDF reader in Microsoft Edge.
Annotations and labeling are part of the PDF format and are saved separately from the content of the document. This means markups you have made in one program will also appear in other programs but may look different. Lines, geometric shapes, and freeform shapes you have drawn should look more or less the same,
