Hash Generator vs URL Encoder / Decoder

Compute cryptographic hashes of any UTF-8 string using the most common algorithms: MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Output is a lowercase hex or base64 digest. Useful for verifying data integrity, generating checksums, and working with APIs that require signed requests.

{
  "input": "Hello, World!",
  "algorithm": "sha256",
  "encoding": "hex"
}

Encode any string for safe use in a URL or query parameter using percent-encoding (RFC 3986), or decode a percent-encoded string back to plain text. Supports both full URL encoding (preserves ://?=& structure) and component encoding (encodes every special character). Shows a character-by-character encoding table for reference.

{
  "input": "hello world & more=stuff",
  "mode": "encode-component"
}
