Description
PDFSeal is an open-source, client-side PDF toolkit powered by WebAssembly. Merge, compress (with exact 2MB/5MB target bisection), physically redact sensitive bytes, sign, watermark, and build automated multi-step pipelines. Everything runs 100% locally in your browser RAM with zero server uploads and zero tracking. 100% offline-ready PWA.
