Frequently Asked Questions About DATA & DEVELOPER TOOLS to OVERVIEW Conversion
Everything you need to know about formats, privacy, and browser-based file conversion.
Are API keys or JWT tokens safe to paste into these tools?
Yes. All parsing, validation, hashing, and encoding happen strictly in client-side JavaScript. No tokens, secrets, or payloads are transmitted to any server.
Does the JSON formatter support large files?
Yes, the formatter runs in browser memory and comfortably parses multi-megabyte payloads without network timeouts or upload bandwidth bottlenecks.
What standards do the hash and UUID generators adhere to?
UUIDs are generated using the Web Crypto API compliant with RFC 4122 v4 standards, while hash functions leverage native browser crypto implementations (SHA-256, SHA-512, MD5).
