Free, browser-based tools — no signup, no watermark, nothing uploaded to a server. A music visualizer with 9:16 export for TikTok/Reels/Shorts, a full PDF toolkit (merge, split, rotate, sign, watermark, convert), a QR code generator (Link/WiFi/WhatsApp/Email/Event+), and a caption/subtitle generator with optional in-browser AI transcription. Built so everyday tools don't need an account or subscription.
