Tracking since Apr 1, 2026.

Changelog

• Jun 22, 2026
  description

  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
  • Debugging auth flows? Decode JWTs without leaking session data to jwt.io.
  • Inspecting API responses? Pretty-print JSON or decode Base64 in one keystroke.
  • Verifying file integrity? Generate any hash locally.
  
  PRIVACY & PERMISSIONS
  • No login, no signup, no account.
  • No external API calls. All cryptography uses Web Crypto API.
  • Permissions: clipboardWrite (Copy button), activeTab + scripting + contextMenus (right-click menu). Nothing more.
  
  FAQ
  Q: How do I decode a JWT in Chrome without a third-party site?
  A: Right-click any JWT on a webpage and select "Decode JWT".
  
  Q: Does this work offline?
  A: Yes. No internet required after install.
  
  Q: Is the source open?

  Decode JWT tokens, Base64 and URLs without pasting them into a stranger's website. YG Encoder/Decoder runs every operation 100% locally in your browser — your tokens, API responses and query strings never leave your machine.
  
  WHY DEVELOPERS PICK IT
  • Privacy-first: inspect JWTs locally instead of uploading them to a website — your content is never sent anywhere
  • 6 tools in one — replaces a stack of single-purpose extensions
  • ~41 KB download — vanilla JavaScript, zero dependencies, instant popup
  • Right-click any selected text on any page to encode, decode or hash it
  • History of your last 50 operations, one click to reload
  • Dark mode and light mode
  
  WHAT'S INSIDE
  • JWT decoder — header, payload and signature in separate color-coded panels
  • Base64 encoder/decoder — full Unicode support, for API responses and data URIs
  • URL encode/decode — query strings, redirect params, special characters
  • HTML entity decoder — debug XSS-prone inputs safely
  • JSON formatter — prettify and minify with one click
  • Hash generator — MD5, SHA-1, SHA-256, SHA-512 via the browser's Web Crypto API
  
  BUILT FOR DAILY DEV WORK
  • Debugging auth flows? Inspect a token's claims locally.
  • Reading API responses? Pretty-print JSON or convert Base64 with one keystroke (Ctrl+Enter / Alt+Enter).
  • Verifying checksums? Generate MD5 or SHA-256 hashes offline.
  • On any webpage: select text → right-click → pick an operation → the result lands in your clipboard with an on-page confirmation.
  
  PRIVACY & PERMISSIONS
  • Your tokens, strings and JSON never leave the browser — all processing is 100% local
  • Anonymous usage statistics (which tools get used) — opt out anytime in the Support tab
  • No account, no signup, all tools work offline
  • Permissions: clipboardWrite (Copy button), activeTab + scripting + contextMenus (right-click menu), google-analytics.com (anonymous usage stats only)
