Frequently Asked Questions

Do I need to create an account to use these tools?

No. All tools on Humanify.pro are completely free and require no login, signup, or email address. Just open the tool and start using it instantly.

Are my files uploaded to your server?

Never. All image compression, conversion, and text processing happens locally in your browser. Your files and text never leave your device – completely private.

Why do I need a Gemini API key for AI tools?

The AI Detector and AI Humanizer use Google’s Gemini models. You get a free API key from Google AI Studio, and it’s stored only in your browser. This keeps the tools free and private – we never see or store your key.

Is there a limit on how many times I can use these tools?

No limits for image tools, Word Counter, or Case Converter. For AI tools, the free Gemini API has rate limits (about 15 requests per minute), but that’s generous for individual use.

Can I use these tools on mobile?

Absolutely. All tools are fully responsive and work on smartphones, tablets, and desktops. The interface adapts to your screen size.
