Convert Word to PDF

PDF files are preferred over Word documents because they are safe, simple to open, and easy to manage on any device. PDF is the most popular file format that users would convert Word to.

Compare Documents

If you receive two nearly-identical Word documents, the ideal way to determine whether there are any differences between them is to compare the two documents.

Extract Text and Images

When you just need to get the information in a Word document regardless of its format and structure, you can simply extract the text and images from the document.

Add a Watermark

A watermark is used to declare confidentiality, copyright, or other attributes of the document, or as a decoration to make the document more attractive. You can add either text or image watermarks to Word documents.

Replace Text

The ability to replace existing text (or placeholders) in a Word document makes it possible for programmers to quickly generate Word reports or documents based on a template.

Find and Highlight

If you want to emphasize some words, you can find and highlight them in a bright color so that the readers could catch them easily.

Headers and Footers

Headers and footers are useful for including information that you want to appear on every page of a document, such as company logo or page number.

Create a Form

Form fields make it easier to collect information. Users can enter information by choosing an item from a drop-down list, inserting text in a combo box, or checking a check box.
