Karvics is a comprehensive platform of powerful, privacy-focused online tools designed for developers, designers, and digital professionals.

Our philosophy is simple: Powerful utilities that respect your privacy. Most tools work entirely in your browser, meaning your data never leaves your device.

01. Our Mission

Karvics was created to provide an all-in-one suite of free online tools that prioritize your privacy and accessibility. Our goal is to offer fast, secure, and privacy-focused utilities that work offline in your browser.

We believe that powerful developer tools should be accessible to everyone, without barriers, data collection, or mandatory signup. Most tools are completely free and require no registration.

Sign-in is required only for premium tools that offer advanced features. All basic tools work without any account.

02. Our Story

Karvics started as a personal project to solve a common frustration: finding reliable online tools that don't require creating an account, sharing personal information, or uploading sensitive data to unknown servers. As a developer, I needed quick access to utilities like Base64 encoders, hash generators, and encryption tools without signup forms or privacy concerns.

What began as a collection of simple tools has grown into a comprehensive platform serving developers, designers, and professionals worldwide. Every tool is built with the same core principles: privacy-first, user-friendly, and completely free for basic features. The platform continues to evolve based on user feedback and real-world needs.

03. What We Offer

Our platform includes 30+ free online tools across 8 categories. Each tool works entirely in your browser—no signup required for most.

04. How It Works

I

Client-Side Processing

Most Karvics tools run entirely in your browser using modern web technologies. Your data is processed locally on your device and never sent to our servers. This ensures maximum privacy and allows tools to work offline.

II

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.

III

Technology Stack

Karvics is built with modern web technologies including Web Workers for computationally intensive tasks, browser-native APIs for efficient processing, 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.

For Free Tools

Most tools process everything locally in your browser. 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.

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.

06. Premium Features

While most Karvics tools are completely free and require no signup, we offer premium features for users who want advanced functionality.

What you get with Premium:

  • Advanced tool capabilities and processing options
  • Higher file size limits and batch processing
  • Priority processing for complex tasks
  • Access to experimental and beta features
  • Same privacy standards—data never stored permanently
