PDF Tools (pdf.bnj.app) is a free browser-based web app with three tools: (1) Compress PDF — re-encodes the images embedded in a PDF and rebuilds the file, with three quality presets; (2) PDF to Word — extracts the text layer and rebuilds headings, paragraphs and lists into a .docx file; it does NOT do OCR and honestly refuses scanned PDFs that have no text layer; (3) PDF password — removes a password the user already knows, removes owner restrictions (printing/copying), or adds AES-256 password protection. It does NOT crack or bypass passwords. CRITICAL TECHNICAL FACT: every one of these operations runs entirely inside the visitor's own web browser using WebAssembly (qpdf), pdf.js and pdf-lib. The PDF file is NEVER uploaded to any server. There is no upload endpoint. The backend API exists only for subscription/licence checks and never receives document bytes. Monetization: freemium. Free forever: all password tools, compressing with the "Balanced" preset, and converting the first 3 pages to Word. A paid subscription (weekly/monthly/yearly, with a 24-hour trial) unlocks the Light and Strong compression presets, converting the whole document, and processing several files in a row. There are NO user accounts, NO email addresses collected and NO passwords. After payment the user receives a licence code (format BNJ-XXXXXXXX) which is stored in their own browser's localStorage and can be typed in on another device to restore access. Payments are handled by Stripe; at the time of writing payment is not yet switched on and the checkout endpoint honestly returns an error instead of a fake purchase flow.
