What are Encoding Tools?

Encoding tools convert data between different formats for transmission, storage, and security. From Base64 encoding for binary data to SHA-256 hashing for password storage, these tools are essential for web developers and security professionals.

All hashing and encoding operations happen client-side in your browser — your sensitive data is never sent to our servers.

Key Benefits

  • Base64 encode/decode for binary and text data
  • URL encode/decode for safe URL transmission
  • HTML entity encoding to prevent XSS attacks
  • MD5, SHA1, SHA256, SHA512 hash generation
  • BCrypt hashing for secure password storage
  • All operations run in your browser — fully private

Frequently Asked Questions

No — Base64 is an encoding scheme, not encryption. It converts binary data to ASCII text but does not provide security. Anyone can decode it.

For password storage, use BCrypt. For file integrity, SHA-256 or SHA-512. Avoid MD5 and SHA1 for security-sensitive applications as they are deprecated for cryptographic use.

No — all encoding and hashing operations happen in your browser using JavaScript. Your data never leaves your device.

No — hash functions are one-way. You cannot reverse a hash to get the original input. This is by design for security.
