The Problem

Most online PDF and image utilities require uploading sensitive documents to third-party servers, creating severe privacy risks and slow processing times.

The Solution

Built a privacy-first web application leveraging client-side WebAssembly, Canvas API, and Web Crypto to process files entirely in-browser without data leaving the user's device.

OmniUtil (util.ivylabs.in) is a suite of privacy-first browser utility tools. All processing — from HD custom QR code generation and image upscaling to PDF compression and AES-256 encryption — runs 100% client-side in the user's browser with zero server uploads.
