PDF-Guru: An Open-Source PDF File Processing Tool 104

PDF Guru is a universal PDF file processing tool that includes more than 20 commonly used features such as PDF merging, splitting, rotation, watermarking, encryption, and conversion. It is fully open-source, free for personal use, with a clean and user-friendly interface.

Although there are many PDF processing tools available online, they all have some drawbacks:

• Professional PDF editing software requires payment or limits features for advanced functions (such as adding watermarks, page editing, etc.)

• Online PDF tool websites require uploading PDFs to a server for processing and then downloading them, posing a risk of privacy leakage

• PDF processing libraries for various programming languages can implement some advanced features for free, but they require certain programming experience and are not as convenient to use as graphical interface programs

• Some niche tools can meet certain special needs but have relatively limited functionality

Since PDF processing is a very common need, this project was created to bypass the above limitations and improve work efficiency.
