PDF Master

A modern web app for working with PDF files directly in the browser. It lets you split, merge, and organize pages without needing desktop software.

What this app does

This project provides a simple PDF toolkit with these main actions:

• Split a PDF into multiple files using custom page ranges, fixed-size chunks, single-page PDFs, or selected pages.
• Merge several PDFs into one document and reorder the files before exporting.
• Organize pages by rotating, deleting, duplicating, reordering, and previewing them.
• Add page numbers and edit PDF metadata such as title, author, and subject.
• Generate a sample PDF for testing the interface quickly.

Built with
