PDFCraft is a browser-based PDF toolkit that processes documents entirely client-side without uploading files to servers.
The tool addresses the privacy and security concerns of online PDF services by running all operations in the browser using WebAssembly technology. It offers over eighty tools covering editing, conversion, merging, splitting, compression, and security operations. The approach keeps user documents on their device throughout processing, eliminating exposure to external servers while maintaining performance through Next.js and WebAssembly.
PDFCraft suits developers and end users who handle sensitive PDF documents and need assurance that files remain private. It works well for individuals processing documents locally, teams with privacy requirements, and workflows where server-based processing is unacceptable. The project distinguishes itself through its visual workflow editor, which allows chaining multiple PDF operations together with drag-and-drop simplicity, batch processing capabilities, and pre-built templates for common tasks like merging and compression, secure PDF creation, and document preparation. The tool supports multiple languages including English, Spanish, French, German, Portuguese, Japanese, Korean, and Chinese.
The project receives issue reports primarily from outside users rather than the core team, indicating an established user base encountering real-world scenarios. Maintainers typically respond to new issues and pull requests within a day.
