Edit, convert, and transform documents across PDFs, Office formats, HTML, TXT, CSV, RTF, JSON, and images with ComPDF Self-hosted, an open-source PDF platform.
High-performance PDF library for C# and .NET. Merge, split, rotate, crop, remove pages, edit metadata, add watermarks, encrypt/decrypt PDFs, apply password protection, perform Tesseract OCR, and reduce file size with advanced PDF compression and image optimization.
PDF password recovery — 100% private, runs entirely in your browser (client-side). Features a smart Pattern Builder (define character sets, ranges & known fragments), multi-threaded brute-forcing via Web Workers, and a responsive dark mode UI. Your files never leave your device.
Minimal PDF encrypt/decrypt with AES-256 (Rev 5). Buffer in, buffer out. Zero crypto deps.
Add a description, image, and links to the pdf-decryption topic page so that developers can more easily learn about it.
