Why Group of Dada

Built from scratch for maximum speed, security, and developer joy.

Most online PDF convertors force you to upload personal financial papers, legal drafts, and medical records to their centralized cloud servers. We took a fundamentally different approach.

True Local-First Privacy

Your files are never transmitted to any third-party server. Everything is rendered via HTML5 canvas and WebAssembly inside your browser.

Zero Upload Latency

Don’t wait 10 minutes to upload a 200MB PDF. Processing begins in milliseconds using your device’s multi-core CPU.

Zero Hidden Fees & Unlimited Usage

No subscriptions, no annoying page limits, and no watermark stamps on your finished documents.

groupofdada-client-engine.ts
import { DadaPDFEngine } from '@groupofdada/core';

// 1. Initialize local browser pipeline
const engine = new DadaPDFEngine({
  privacyMode: 'zero-knowledge-ram',
  webAssemblyAcceleration: true
});

// 2. Merge PDF documents locally
const mergedDoc = await engine.merge([
  docA.arrayBuffer(),
  docB.arrayBuffer()
]);

// 3. Export high-fidelity PDF without server roundtrips
const downloadUrl = await engine.toBlobUrl(mergedDoc);
console.log(`✅ Done in 18ms! Memory purged.`);

100% Privacy & Security Guarantee

Your Documents Are 100% Safe, Private & Secure

We built Group of Dada with one simple rule: your documents belong only to you. We don't read them, we don't store them, and we never share your data.

Files Stay on Your Device

Your files are processed directly on your phone or computer. Nothing is uploaded to external cloud servers, so no one on the internet can see or read your documents.

Zero server uploads

Zero Files Saved on Disk

We never save or archive a copy of your files. The moment you finish downloading your converted or merged PDF, it is instantly wiped clean. No history is kept.

No file history retained

No Sign-Up for Web Tools

No email address, no phone number and no password needed to use the tools on this website. Our Android apps offer optional Google sign-in (see each app's privacy policy).

No account needed on the web

100% Watermark-Free

Unlike other websites that put ugly brand logos across your finished work, Group of Dada keeps your files completely clean and original for professional use.

Clean, original documents

Password Protection

Easily lock your confidential bank statements, contracts, or tax papers with your own secret password. Only people with your password can open them.

Secure password locking

Free forever with zero traps

Simple, Honest & Safe

Built to make handling documents easy and secure on Android and the web.

Why We Built Group of Dada

Founder's Vision • Sudip Pal

Every day, millions of students, accountants, legal practitioners, and small businesses need to convert an image to PDF, merge bank statements, or scan QR codes. Yet mainstream tools exploit them with predatory $15-$25/month subscriptions, ugly watermarks, and invasive cloud tracking.

At the same time, thousands of talented solo developers and funny-reel creators in India work completely alone — struggling with Google Play's 20-tester closed testing barrier and earning ₹0 from their hard work.

Group of Dada unites both worlds. We engineer zero-cloud, 100% on-device software (PDF Tools, Password Recovery, QR Generator) and offer independent builders an end-to-end launchpad with viral video marketing, 20-tester community access, and a fair, flexible revenue share where you earn first.

Zero Dark Patterns

No hidden credit card charges, no fake countdown timers, and no forced page watermarks on your finished documents.

Client-First Performance

Built with high-throughput WebAssembly and native Android Kotlin for instantaneous file parsing and batch exporting.

Absolute Data Sovereignty

Your files remain your property on your physical hardware. We never store your files or chats on our servers.
