How this service works

Convert integers of any size (signed) between bases 2 to 36: binary, octal, decimal, hex, base32, base36, with bit and byte length and two's complement. Accepts 0x/0b/0o prefixes.

Output

A JSON object containing the original input string, the detected or specified input base, the decimal canonical form, bit length, byte length, and a 'conversiones' map from each requested output base (as a string key) to the converted value string.

Example use cases

Hex color code to binary breakdown

“Take the hex value 0x1A3F and convert it to binary, decimal, and octal — and tell me how many bits wide it is.”

Signed negative integer in two's complement

“What does -128 look like in binary (two's complement), hex, and octal? Also tell me the bit and byte length.”

Base 36 encoding for compact IDs

“Convert the decimal number 987654321 to base 36 and base 16 so I can use it as a compact identifier.”

Endpoint

When to prefer

Choose this endpoint when you need multi-base integer conversion with metadata (bit/byte length, two's complement) in a single call, especially when handling prefixed literals like 0x, 0b, or 0o. Prefer it over general-purpose code execution when you want a lightweight, deterministic, paid-API conversion without spinning up a runtime.

Side effects

Missing required 'valor' field returns a validation error
Invalid characters for the specified input base cause a parse error
Unsupported base (outside 2–36) returns an error
Extremely large integers may hit processing limits
Malformed prefix (e.g. '0x' with no digits) may return a null or error response
