Why a Base64 tools hub?

People search separately for validators, repair tools, JWT decoders and data-URI converters. This hub connects them so Google and users both find the full toolkit — in every language we ship.

  • Correctness first — standards, padding and charsets explained when something breaks.
  • Privacy first — browser-local processing; no account, no upload for core Base64 work.
  • Learn next — guides and blog posts link back to the exact tool you need.
