About converters

Converters for data and everyday values: validate IBANs, convert Unix timestamps and time zones, translate between number bases and units, encode Base64 and URLs, switch between JSON, YAML, TOML, XML and CSV, convert colour formats and turn text into Unicode escapes or Morse code.

Conversions are computed locally, with no rate limits and no account.

Frequently asked questions

Do the converters handle large files?
Yes — file-based converters such as Base64 File Converter and JSON/CSV work with anything your browser's memory can hold, typically hundreds of megabytes.
Are the results accurate for financial use?
Validators like the IBAN checker follow the official standards (ISO 13616 and the SWIFT registry). They confirm a number is well-formed, not that an account exists — always confirm with the bank for large payments.
