Most online utility websites work the same way: you upload a confidential PDF, photo, or audio file to a random server, wait in a queue, dodge popups, and hit a paywall when you try to download the result.
I got tired of that pattern and built DodoDeck — a suite of 14 everyday tools that execute 100% locally inside your browser using WebAssembly and WebGPU. When you close the tab, your data is gone. Zero server uploads.
What Runs Locally in Your Browser:
- Free Online PDF Editor — Edit text directly, whiteout watermarks, add signatures, and format with Unicode or Bengali fonts (Bijoy 52 / SutonnyMJ).
- AI Background Remover — Runs on your local GPU via WebGPU with HD transparent PNG export and batch mode.
- Dodo File Share — Send up to 1GB directly browser-to-browser via WebRTC.
- 2FA TOTP Generator, URL Shortener, QR & Barcode Maker, SmartWriter, Text-to-Audio, Audio-to-Text, and Image Resizer — zero tracking, zero artificial limits.
Two Free Chrome Extensions (Zero Paywalls):
- TakeFullPage (Install on Chrome Web Store) — Full-page scrolling & selected-area screenshots with a built-in editor (crop, pen, arrows, highlight, blur redaction) and 1-click export to HQ PNG, PDF, clipboard, or Telegram.
- Dodo Password Manager (Install on Chrome Web Store) — Zero-knowledge AES-GCM-256 vault (600,000 PBKDF2-SHA256 rounds), 1-click autofill, FIDO2 passkeys, and built-in 2FA TOTP with unlimited free device sync.
Would love feedback from fellow developers on the WebAssembly / WebGPU performance and security architecture!
