# Docswift

> Enterprise-Grade Online Document, Image & Media Conversion Suite. Fast, privacy-first, in-memory processing with 82 free production-ready converters and micro-tools.

Docswift (https://www.docswiftconverter.com) provides instant, client-and-server document processing with zero watermarks, zero permanent file storage, and no registration required. The platform supports documents (PDF, Word, Excel, PPTX), images (JPG, PNG, WebP, SVG, HEIC), audio/video (MP3, WAV, MP4, WebM), and developer/data utilities.

## Core Features & System Capabilities

- **Zero Data Retention**: Files are processed in-memory or in ephemeral OS temporary directories with instant cleanup via `try...finally`.
- **PC-to-Mobile QR Transfer**: Send converted files directly to smartphones via single-use QR codes (`/d/[token]`, 5-minute TTL).
- **Gemini AI Multimodal**: AI-powered document summaries, conversational Q&A, and OCR via Google Gemini Flash.
- **Client & Server Processing**: Heavy visual transforms handled via `sharp` and `pdf-lib` server-side; real-time audio and canvas tools run in-browser.
- **Strict Validation**: MIME and binary magic-byte detection prevent file spoofing. Maximum file size: 50MB per file.
