Master PDF Editor

About

Master PDF Editor is a straightforward, easy-to-use application for working with PDF documents, offering multi-purpose functionality for viewing, creating, and modifying PDF files. It lets you merge several files into one, split a source document into multiple documents, and comment, sign, and encrypt PDFs. You can add or edit text with various formatting, insert and move images and objects, and use annotation tools such as sticky notes, measuring tools, shapes, strikethrough, underline, highlight, and custom stamps.

The app also covers forms, OCR, and page management. It supports editing interactive PDF form elements such as buttons, text fields, and checkboxes, with JavaScript automatic calculation and data validation. Optical character recognition makes text searchable and allows editing of scanned documents. You can move, remove, insert, rotate, and resize pages, and create, edit, and remove bookmarks for fast navigation. Digital signatures can be checked, created, and applied with a digital signing certificate, and PDFs can be created from paper documents via a scanner, from existing files, or as empty documents. A demo version is available with all features, though it adds a watermark to the output.
