よくある質問 (FAQ)

What developer tools are available on ToolsTier?

ToolsTier includes a JSON Formatter & Validator, Markdown Editor & HTML Converter, SHA-256/512 and MD5 Hash Generator, UTF-8 Base64 tool, Cryptographic Password Generator, Word Counter, Text Diff Checker, Text Cleaner, URL Encoder, and Live Regex Tester.

Do these tools run entirely in the browser?

Yes 100%. All cryptographic hashing, Base64 conversion, password generation, and text diffing execute client-side via the Web Crypto API. No data or secrets are sent to any remote server.

Does the Base64 tool preserve non-English text and UTF-8?

Yes, our encoder and decoder handle multi-byte UTF-8 bytes natively, ensuring Arabic, Asian characters, and emoji remain intact without character corruption.

How does the password generator ensure strong security?

It uses window.crypto.getRandomValues for hardware-backed cryptographic randomness and evaluates entropy bits to guarantee resistance against brute-force attacks.
