Your documents are your most sensitive personal and business assets. Why rent them back to cloud converters? Every mainstream online utility uploads your tax filings, contracts, resumes, and medical scans to remote servers, charging monthly fees while harvesting metadata. DocEasy flips the paradigm: compress, merge, convert, crop, and inspect documents directly on your device — 12 verified tools, instant execution, and zero outbound network traffic for local workflows.
Tip
Client-First Hybrid Architecture. Core operations (PDF compression, merger, converter, photo editor, cropper, resume scoring) run 100% locally in your browser's WebAssembly sandbox. Heavy compression can optionally route to ephemeral server-side Ghostscript/qpdf workers with immediate memory purge. Cloud persistence is strictly opt-in and safeguarded by Supabase Postgres Row-Level Security (RLS).

- Client Execution Layer — Runs in-memory inside modern browser sandboxes via WebAssembly and Canvas APIs. No file leaves your machine for core tasks.
- Ephemeral Processing Pipeline — Server-side API route (
/api/compression) provides heavyweight processing (Ghostscript/qpdf) with immediate post-process file unlinking. - Authenticated Cloud Vault — Protected storage powered by Supabase Auth and Postgres Row Level Security (RLS), giving authenticated users persistent access across devices.
DocEasy is engineered around verifiable privacy principles:
- Client-First Execution — Operations happen in client memory by default. Open DevTools Network tab: verify 0 bytes outbound during local merges, conversions, and client compression.
- Ephemeral Backend Buffering — When server acceleration is selected for heavy compression, files are processed in isolated temporary storage and immediately purged upon response delivery.
- Cryptographic Session Vault — Local vault files utilize the Web Crypto API (
SubtleCrypto) with 256-bit AES-GCM encryption keys held in volatile session memory. - Postgres Row Level Security (RLS) — Persistent cloud vault data is gated by strict Supabase RLS policies; users can only read, write, or delete their own authenticated files.
- Zero Telemetry — No tracking pixels, no session replay scripts, no Google Analytics, and no marketing beacons.
- Node.js: 20.9+ / 22.x+
- Package Manager:
npm,pnpm, oryarn
