Encode Unicode text as RFC 4648 Base64 or decode percent-encoded and form-plus URL text with explicit malformed-input errors.

Base64 Text EncoderEncode browser text as UTF-8 bytes and RFC 4648 standard Base64, with exact Unicode handling, byte count, copy, text-file import, and download. Ideal for developers preparing payloads for APIs, data URIs, email attachments, and authentication headers. Handles full Unicode range with transparent byte counting.Code & Web / EncodersTry it
Percent Encoding DecoderDecode one percent-encoded UTF-8 string locally with decodeURIComponent, treating plus signs as spaces, and report invalid escape sequences instead of returning partial output. Essential for developers debugging URL parameters, parsing form submissions, and inspecting encoded API query strings.Code & Web / EncodersTry it
