Frequently Asked Questions
Common questions about using ToolsCorner.
Are ToolsCorner tools free?
Yes. All 267 tools are free with no account required.
Do tools upload my files?
File-based tools (image, PDF) process files locally in your browser. We do not receive your files. Network diagnostic tools may query public APIs — each tool page indicates its behavior.
Which tools work entirely locally?
Image, PDF, text, developer, generator, and calculator tools run in your browser. IP lookup, DNS lookup, and latency test use external services and are labeled on the tool page.
Can I use ToolsCorner on mobile?
Yes. The site is mobile-first and responsive. File upload works on modern Android Chrome and iOS Safari where browser APIs allow.
Do I need an account?
No. Favorites and recently used tools are stored in your browser localStorage only.
How does privacy work?
Tools marked with a local-processing badge keep data on your device. We do not collect tool inputs on our servers.
Are calculator results guaranteed?
No. Results use standard formulas and are estimates. Finance and health tools are not professional advice.
Can I use the tools commercially?
Yes, subject to our Terms of Service. Verify important outputs independently.
How do external-service tools work?
Some security tools send requests from your browser to public APIs (e.g. IP lookup). Your files are never uploaded.
How can I report an issue?
Email konsitaski@gmail.com with the tool name, browser, and steps to reproduce.
