PDF-PRO is a professional PDF editing tool developed by Hoà Quang Thắng, integrating the 8 most important features for document processing. From merging files, arranging pages, splitting PDFs, extracting text and images, to directly editing content, digitally signing, exporting data to Excel, and compressing file size — all are included in a lightweight yet powerful desktop application. The combination of PyMuPDF, pypdf, and CustomTkinter provides a smooth experience, with a minimalist interface in friendly Vietnamese, helping users process PDFs quickly without an internet connection.

The idea for developing PDF-PRO arose from the author's observation that online PDF tools often limit file size, require network access, and compromise privacy. Therefore, an offline desktop solution, free of charge, that respects user privacy was created. The development process focused on the 8 core features, optimizing performance for each action, from reading hundreds of pages of files to exporting spreadsheet data. PDF-PRO is a reliable choice for students, office workers, and anyone who needs to work with PDFs every day.
