Intuitive Coordinate-Based Positioning

This online PDF editor is designed to be intuitive and accessible to users of all skill levels.

The tool supports adding multiple text annotations across different pages, making it ideal for creating comprehensive document markups, adding page numbers, inserting labels, or placing custom text watermarks.

Client-Side Processing for Privacy

Unlike many online PDF editors that upload your files to external servers for processing, this tool performs all operations locally within your web browser. Your documents are processed using JavaScript and WebAssembly technologies, ensuring that your data remains private and secure throughout the entire editing process. This makes it particularly suitable for handling sensitive business documents, legal papers, medical records, or any confidential information that should not be transmitted over the internet.

Flexible Text Customization

The PDF annotation tool offers flexible text customization options. You can adjust the font size of your annotations to match your document existing typography or create prominent headers and labels. Each annotation can be placed on a specific page, allowing you to add different text to different sections of your multi-page PDF documents. The coordinate system uses the bottom-left corner of each page as the origin point, with X values increasing horizontally from left to right and Y values increasing vertically from bottom to top.

You can access it from any modern web browser on Windows, Mac, Linux, or mobile devices without paying anything or signing up for an account.

Fast and Efficient

The tool client-side processing also provides significant advantages in terms of speed and efficiency. Since your PDF files do not need to be uploaded to a server and then downloaded again, the editing process happens almost instantaneously. This is particularly beneficial when working with large PDF documents or when you have limited internet bandwidth. You can edit multiple PDF files in quick succession without experiencing the delays often associated with cloud-based alternatives.
