Absolutely! TCB Tools is completely free with no hidden costs, subscriptions, premium tiers, or usage limitations. You get unlimited access to all tools without watermarks, file size restrictions (beyond browser memory), daily limits, or registration requirements. We believe professional-grade tools should be accessible to everyone, whether you're a student, freelancer, or enterprise developer.

Security and privacy are our core principles. All tools use 100% client-side processing - your files, images, text, and data are processed entirely in your browser using JavaScript. Nothing is uploaded to servers, stored in databases, or transmitted over the internet. Your sensitive data like JWT tokens, images, and documents never leave your device, ensuring complete privacy and GDPR compliance.

TCB Tools works on all modern browsers (Chrome, Firefox, Safari, Edge) and is fully responsive across desktop, laptop, tablet, and mobile devices. No plugins, extensions, or special software required - just a modern browser with JavaScript enabled. Our mobile-first design ensures optimal performance on smartphones and tablets.

Yes! You can use TCB Tools for personal, commercial, and client projects without any restrictions, licensing fees, or attribution requirements. Perfect for agencies, freelancers, enterprises, and businesses of all sizes. Generate QR codes for marketing campaigns, convert images for websites, decode JWTs for development, and format code for client deliverables - all completely free.

We don't impose artificial limitations. File size limits are only constrained by your browser's memory capacity and device performance. Use our tools unlimited times per day without throttling, daily caps, or account restrictions. Process thousands of images, generate hundreds of QR codes, or format massive JSON files - all without limits.

We're continuously expanding based on user feedback. Currently developing: Advanced PDF tools, Enhanced encryption utilities, Website screenshot tools, API testing utilities, Markdown to HTML converter, Code minifiers/beautifiers, and Advanced image editing features. Follow our updates for the latest tool releases.
