  Dev Passa is a lightweight developer toolbox for screenshots, annotations, JSON visualization, JWT decoding, encoding/decoding, and timestamp conversion.
  
  Chrome Web Store Description
  Dev Passa brings everyday developer utilities into one simple Chrome extension.
  
  Capture selected areas of any webpage, annotate screenshots with rectangles, highlights, and text, then save or copy the edited image. Open the JSON Visualization tool to format JSON, escape/unescape strings, inspect data in a tree, or render nested JSON as a readable table.
  
  Dev Passa also includes quick tools for decoding JWT tokens, Base64 and URL encoding/decoding, and converting timestamps across local time, UTC, and selected timezones.
  
  Features:
  
  Selected-area screenshot capture
  Screenshot annotation editor
  Red/green rectangles, highlights, and text labels
  JSON formatter
  JSON escape and unescape
  JSON Compare
  Cron Expression evaluator
  Collapsible JSON tree view
  Nested JSON table visualization
  JWT decoder with header, payload, claims, and expiry details
  Base64 encode/decode
  URL encode/decode

  Dev Passa is a lightweight all-in-one Chrome extension built to help developers, testers, support engineers, and technical users work faster inside the browser.

You can capture screenshots, annotate images, inspect and compare structured data, decode tokens, convert timestamps, work with cron expressions, and use encoding and crypto helpers without leaving Chrome.
