Why use this Base64 tool?

Text is encoded and decoded entirely in your browser using correct UTF-8 handling, so accented characters and emoji round-trip exactly instead of becoming corrupted, which is a common problem with simpler Base64 tools.

Common use cases

  • Decode a JWT token segment for debugging
  • Encode text for a data URI
  • Inspect a Base64-encoded API response

Frequently asked questions

Is my text uploaded anywhere?

No. Encoding and decoding happen locally in your browser. Nothing you enter is sent to Inqita or stored.

Does this handle emoji and accented characters correctly?

Yes. Text is converted using UTF-8-safe encoding, so non-English characters and emoji encode and decode without corruption.

What happens if I try to decode invalid Base64?

A clear error is shown instead of a raw browser exception.

What is Base64 used for?

Base64 represents binary or text data as plain ASCII characters, commonly used in data URIs, email attachments, and API tokens like JWTs.

Does this work on mobile?

Yes. The input and output areas adapt to mobile screens.
