Frequently Asked Questions

Are string tools safe to use with sensitive data?
Yes. All string processing happens locally in your browser. Your text never leaves your device and is never uploaded to our servers.
Do I need to install any software?
No, all string tools work entirely in your web browser. Just paste your text and start using the tools immediately.
Can I process large amounts of text?
Yes, since processing is client-side, you can handle large text files. The limit depends on your browser memory, but most tools handle several megabytes smoothly.
Are the hash functions secure?
Our hash generators use industry-standard algorithms (MD5, SHA-256, SHA-512). However, for password hashing, use bcrypt or Argon2 instead.
