Redline PDF documents often refer to annotating PDFs using a PDF editor. Luckily, SwifDoo PDF is such a comprehensive PDF annotator that enables you to redline PDF documents effortlessly and efficiently. With the help of SwifDoo PDF, you can easily redline a PDF by using the following features:
Strikethrough text means putting a line through selected text, indicating crossing out the content. This action is widely accepted when you need to point out a mistake and make sure others know. SwifDoo PDF offers a series of text markup tools, helping you easily strikethrough and underline specific text content, as well as adding squiggly lines and caret to PDF text.
- Add Callout to PDF
A callout annotation adds a text note (contained within a box) to PDF with an arrow that can point to a specified location on a page. You can easily relocate and resize a callout as per your requirements. This is widely used when you need to modify a sentence/paragraph comment on a point of view. In SwifDoo PDF, you can not only easily add text callout in a PDF, but also customize its style and preference.
- Add Attachment to PDF
By adding attachments to PDF, people can access external files without breaking a sweat. Inserting PDF attachments with SwifDoo PDF allows you to attach any kind of file, including PDFs, Office documents, audio, videos, etc.
- Add Notes to PDF
Notes look like callout annotations which we’ve introduced before. However, there are some differences: the outlook of a note is fixed and cannot be modified; a note shows more information than a callout, such as your account information and the specific time you create notes.
- Annotate PDFs by adding notes, bookmarks, etc.
