About This Project
PDFCraft delivers a comprehensive suite of over 90 PDF manipulation tools that execute entirely within the browser environment. Built with JavaScript, this toolkit ensures complete data privacy by processing all PDF operations locally on the user's device, eliminating the need to transmit sensitive documents to external servers.
The project addresses a critical gap in document processing workflows where developers and end-users need powerful PDF capabilities without compromising security or relying on third-party services. From document merging and splitting to format conversion and encryption, every operation happens client-side using modern web APIs and JavaScript libraries.
Key advantages include zero backend infrastructure requirements, making it ideal for embedding in web applications, offline usage scenarios, and situations where data sovereignty is paramount. The extensive tool collection covers professional-grade features like watermarking, OCR, form filling, page manipulation, and compression—all accessible through a browser interface.
With its substantial community adoption reflected in over 1,600 stars, PDFCraft represents a mature solution for developers seeking to integrate PDF functionality into their applications without external dependencies or privacy trade-offs.
