About Base64 ToolsWorkbox

Base64 ToolsWorkbox provides Base64 / Base16 / Base32 encode/decode, JWT payload decode, hex preview, and batch ZIP — entirely in your browser.

It belongs to the ToolsWorkbox tool matrix. You can install it as a PWA when the browser offers; shell cache is offline-capable, payloads stay on-device. Optional blog and admin run on ThinkPHP at the same origin.

Principles

  • Local-first: no upload of encode/decode payloads
  • Prefs only in localStorage — history only when you enable it
  • Encoding is not encryption
  • Same shell UX as sibling ToolsWorkbox sites
