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.

よくある質問

Base64 は暗号化ですか?

No. Base64 is encoding. Anyone can decode it. Use our guides and JWT/secret tools to handle real security correctly.

Do you upload my files?

No. These tools run in your browser. Prefer them over upload-based Base64 sites.
