Description: A complete offline PDF toolkit with editing, annotation, conversion, OCR, fillable forms, redaction, and security features. Files never leave your machine — no uploads, no tracking, no account required. Available for Windows, Linux, and macOS.

It offers far more than viewing — full editing, annotation, forms, OCR, and privacy-focused operations — all running 100% locally.
