FAQ

Common questions

What is TechHowAI?+

TechHowAI is a free online tools platform with 100+ utilities for developers, businesses, students, and everyday users. Tools include JSON formatters, JWT decoders, PDF editors, image compressors, SQL formatters, calculators, and SEO generators — all accessible without signup.

Are TechHowAI tools really free?+

Yes. Every tool on TechHowAI is 100% free with no subscriptions, trial limits, or hidden paywalls. We support the platform through advertising and may introduce optional premium features in the future.

Do I need to create an account?+

No account is required. Open any tool and start using it immediately. Your favorites and recent tools are stored locally in your browser if you choose to use those features.

Is my data private?+

Most tools process data entirely in your browser — your files and text never leave your device. Server-side tools (DNS lookup, SSL checker, etc.) send only the data you submit and do not permanently store it. Read our Privacy Policy for full details.

Can I use TechHowAI on mobile?+

Yes. All tools are responsive and work on phones, tablets, and desktops. The interface supports both dark and light themes for comfortable use in any environment.

How is TechHowAI different from other tool sites?+

TechHowAI combines a modern dark UI, privacy-first client-side processing, comprehensive educational content on every tool page, and AI-search-optimized documentation. We focus on developer experience, accessibility, and fast performance — not cluttered ad-heavy layouts.
