Pdf Editor
This project is a browser-based PDF editor that allows users to modify documents by inserting and repositioning text, images, and signatures. It functions as a client-side document editor, enabling the rendering, editing, and saving of files entirely within the user's browser environment.
By processing all binary data locally, the application ensures that documents are never uploaded to a remote server, maintaining data privacy throughout the editing workflow. The tool utilizes an object-oriented model to manage individual elements, allowing for independent manipulation and transformation of content within the document.
The application supports a range of document annotation and modification tasks, including the application of digital signatures and the customization of text formatting. Users can interact with their files through a canvas-based interface that tracks input for precise element placement and resizing.
