About Us
Karvics is the zero-knowledge toolkit for developers, designers, and technical teams who refuse to upload sensitive data to random servers. Every utility ships its logic to your browser so the code travels to the data—not the other way around.
Our philosophy is simple: powerful utilities that respect your privacy and sovereignty. We run as a PWA, keep processing entirely in RAM, and give you the freedom to disconnect from the internet mid-task without losing functionality.
01. Our Mission
Karvics was created to prove you can have enterprise-grade tooling without compromising data sovereignty. We run on a Zero-Knowledge Architecture: encryption, PDF manipulation, hashing, and AI prep all happen locally so the plain data never hits our servers.
We believe that powerful developer tools should be accessible without uploads, rate limits, or bait-and-switch pricing. That is why the core suite is completely free, requires no registration, and even supports offline execution after the first load.
Sign-in is required only for premium tools that leverage heavy server-side pipelines. Everything else remains zero-upload, zero-tracking, and instantly available.
02. Our Story
Karvics started as a personal project after getting tired of "free" utilities that demanded logins, uploaded sensitive dumps to unknown servers. The goal was to build something you could trust enough to keep the browser DevTools open and verify, packet-by-packet, that nothing ever leaves your machine.
That experiment has since grown into a professional suite serving thousands of privacy-conscious builders. The ethos is unchanged: transparent logic, optional auth, and tooling you can literally run offline. Built by a team of security engineers and full-stack developers, we apply enterprise-grade security practices—like CSP strictness, memory-safe handling, and zero-egress architectures—to everyday free tools. Community feedback via GitHub Issues continues to drive our roadmap.
03. What We Offer

04. How It Works
- 01
Client-Side Processing
Karvics flips the traditional model—our code ships to your browser, executes in memory, and never sends the raw payload back. It is the literal implementation of "code travels to data," delivering zero data egress and enabling fully offline workflows.
- 02
Premium Features
A select few premium tools require authentication and server-side processing for advanced functionality. When you sign in with Google or GitHub OAuth, these tools become available with enhanced capabilities.
- 03
Technology Stack
Karvics is built with modern web technologies including Web Workers for heavy PDF work, Next.js 16+/React 19 for UI, native Web Crypto (AES-GCM) for encryption, and responsive design for all devices.
05. Privacy First
Your privacy is our top priority. We don't require accounts for most tools, collect personal information, or track your activity across the web, and we align with GDPR, HIPAA, and CCPA expectations for zero data egress workflows.
For Free Tools
Most tools process everything locally in your browser using the Web Crypto API and in-memory buffers. Your data never leaves your device, and we never see what you're processing.
For Premium Tools
When server processing is needed, data is transmitted securely, processed immediately, and automatically deleted. We never store your data permanently and publish clear disclosures inside each premium workflow.
We don't use intrusive cookies, third-party trackers, or advertising analytics. The only data we collect is basic, anonymized usage statistics to understand which tools are most helpful.
