Base64 Encoder / Decoder vs Number Base Converter
encoding
Base64 Encoder / Decoder
Encode text or data to Base64, or decode Base64 back to plain text.
Encode any UTF-8 string to Base64 or decode a Base64 string back to plain text. Supports standard Base64 (RFC 4648) and URL-safe Base64 (uses - and _ instead of + and /). Detects and reports malformed input.
Example input:
{
"input": "Hello, World!",
"mode": "encode",
"charset": "standard"
}encoding
Number Base Converter
Convert numbers between binary, octal, decimal, and hexadecimal.
Convert any integer between base 2 (binary), base 8 (octal), base 10 (decimal), and base 16 (hexadecimal). Returns all four representations at once, with grouped formats for readability. Supports arbitrarily large integers via BigInt.
Example input:
{
"input": "255",
"from_base": 10
