## 1. Product Overview
**Product Name:** SimplePDF
**Tagline:** Simple PDF editing, right in your browser
**Core Value Proposition:** For individuals, SimplePDF offers a completely free, no-signup PDF editor in the browser. For companies, it integrates a powerful PDF SDK into websites or apps with one line of code.
**Target User:**
- Individuals, Developers and business professionals that work with PDFs and require editing, annotating and signing.
**Key Benefits And Features:**
For individuals:
- The editor interface is available in Dutch, English, French, German, Italian, Japanese, Portuguese, and Spanish
- Strong emphasis on privacy: the documents and data filled in stay on the device and are never sent to a server
- Works offline: the free editor (and any tenant that does not collect submissions) downloads its PDF engine, its interface copy, and its Latin font faces up front, so a user can disconnect from the internet and still open, fill, sign, and download a PDF; after a session's first offline spell, reconnecting also fetches the remaining non-Latin faces (Arabic, Devanagari, Tamil) and the HEIC photo decoder. Mandarin text, encrypted PDFs, OCR and redaction still need a connection the first time they are used. A Wi-Fi indicator appears in the editor sidebar when the connection drops, green when offline editing is ready and red when it is not, and explains the state when clicked
- HIPAA compliant (editing is fully in-browser: documents never reach SimplePDF servers)
- Add text, checkboxes, signatures, pictures on PDFs
- Add comb fields (one character per box, common on French/CERFA forms like dates, SSN, IBAN, postal codes)
- White out (redact) existing content
- Merge, add, remove and rotate PDF pages
- Add an image (JPG, PNG, HEIC) as a PDF page: it lands on its own A4 page (orientation follows the image) where you can move, resize, and rotate it, entirely in the browser (adding the image does not upload it; HEIC is decoded locally)
- Automatic detecti
