Encoders & Decoders

Encode and decode data in various formats

3 tools

Encode and decode data between formats without sending anything to a server. Base64, URL encoding, HTML entities, JWT inspection — all done client-side so sensitive tokens or payloads never leave your browser.

Base64 Encoder/Decoder

Encode text to Base64 or decode Base64 strings back to plain text.

HTML Encoder/Decoder

Encode special HTML characters to entities or decode HTML entities back to characters.

URL Encoder/Decoder

Encode or decode URLs and query parameters. Handles percent-encoding for safe URL transmission.
