Category FAQ
Are generated passwords and cryptographic hashes secure?
Yes. Passwords and hashes use the browser's native Web Crypto API (crypto.getRandomValues and subtle.digest), ensuring cryptographically secure randomness.
Can I generate bulk UUIDs at once?
Yes, you can generate up to 1,000 UUID v4 strings in a single click and copy them as individual items or a complete list.
Does the code minifier support JavaScript, CSS, and HTML?
Yes, you can minify or beautify JavaScript, CSS, and HTML with real-time file payload reduction statistics.
