Frequently Asked Questions
Are these developer tools free to use?
Yes, all developer tools on Toolifly are completely free with no signup
required. You can use them as much as you need for encoding, decoding, formatting, and
generating data.
Is my data sent to any server?
No. All processing happens locally in your browser using JavaScript.
Your code, text, and data are not sent to external servers during processing. This
browser-based approach helps protect sensitive information.
What hash algorithms are supported?
Our hash generator supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512
algorithms. These are commonly used for data integrity verification and password hashing in
development workflows.
Can I use these tools for production code?
Absolutely. These tools are designed for real development workflows. Use
them to format JSON APIs, encode data for URLs, generate secure passwords, test regex
patterns, and more. The output is production-ready.
Do the tools work offline?
Once loaded, most tools work offline since processing happens in your
browser. However, you need an internet connection to initially access the page. Consider
bookmarking tools you use frequently.
