Jwt Decoder Base64 Url En

YG Encoder/Decoder is a privacy-first, all-in-one Chrome extension for developers.
Encode/decode Base64, URL, HTML, JWT, JSON — plus MD5, SHA-1, SHA-256, SHA-512 hashes.
100% in your browser. No server. No tracking. 42 KB.

WHY USE IT
• 100% offline — JWT tokens, hashes, URL params never leave your browser
• 6 tools in one — replaces 5 single-purpose extensions
• 42 KB total — smallest in its category (vs 545 KB for some JWT-only tools)
• Right-click any selection on any page → encode/decode in place
• History of last 50 operations, instantly recallable
• Dark mode that actually looks good

WHAT IT DOES
• Base64 — encoder/decoder for API responses, image embeds, data URIs
• URL — encoder/decoder for query strings and redirect params
• HTML entity — encoder/decoder to prevent XSS during debugging
• JSON — prettifier + minifier with one click
• JWT — decoder showing header, payload, expiry, signature
• Hash — generator: MD5, SHA-1, SHA-256, SHA-512

FOR DEVELOPERS
