Description
JSON viewer, JWT decoder, screenshot & annotate, photo crop, Parquet, PDF, encoding, timestamp, cron — all local, nothing uploaded. 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. Instead of switching between multiple websites and tools, Dev Passa brings common day-to-day utilities into one convenient place. 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—all without leaving Chrome. 🔥 KEY FEATURES • Screenshot Capture & Annotation: Select an area and add drawings, highlights, and text. • JSON Visualization & Handler: Format JSON effortlessly and open .json files directly in your browser. • Text Compare: Side-by-side diff tool with highlighted changes for JSON, XML, YAML, Properties, and plain text. • Parquet Viewer: Drag-and-drop or load via URL to inspect schemas, browse/filter rows, and export to JSON/CSV. • PDF Utility: View, merge, split, convert to images (PNG/JPEG/WebP), add text overlays, print, and download. • JWT Decoder: Quickly decode and inspect JSON Web Tokens. • Encoding & Crypto Utility: AES, RSA, ECDSA, hashing support, plus Base64 and URL encoding/decoding. • Timestamp Converter: Smart format detection with seamless timezone conversion. • Cron Utility: Validation, schedule preview, and generator support (including Spring Boot cron expressions). 💡 WHY DEV PASSA? • Eliminates the need to bookmark and bounce between dozens of different web utilities. • Accelerates debugging, API inspection, payload comparison, formatting, and time conversion. • Built for privacy: PDF, Parquet, and JSON files are processed 100% locally in your browser memory. No file data is ever uploaded or persisted to any external server. 🎯 WHO IT IS FOR • Software Developers • QA Engineers • Support Teams • API Integrators • Technical Analysts 🚀 LATEST UPDATES Dev Passa v3.0.1 — Patch Release Bug Fixes JSON Detector — Pre-signed URL support: Clicking the JSON button on S3/AWS pre-signed URLs no longer fails with 403. Content is now read directly from the page DOM and passed via storage, bypassing the need to re-fetch an already-expired URL. JSON Detector — Error feedback: Failed attempts now show a small red error pill on the page instead of silently failing, with a 6-second auto-dismiss. JSON Viewer — HTML rejection: Opening a non-JSON page via the right-click context menu now shows a clear error banner instead of dumping raw HTML into the viewer. Both the Content-Type header and body content are checked. JSON Viewer — Source URL display: The "Loaded from" banner now shows a short clickable link instead of the full raw URL, keeping the UI clean for long pre-signed URLs. Version 3.0.0 • Photo Crop Tool — 21 presets (print sizes, 6 passport types with official requirements, social formats), 8-handle crop with rule-of-thirds grid, resolution selector (72–600 DPI), live output size display, preview modal with format/quality choice. All images stay on device. • JSON context menu — right-click any JSON link → opens in Dev Passa's formatter instantly. • JSON page detector — visit any raw JSON URL directly and a floating { } Open in Dev Passa button appears automatically. • Popup redesign — icon grid with categories, tool descriptions, real extension icon in header, v3.0.0 badge. • Privacy — credentials: 'omit' on JSON fetches, photo processing 100% local with a visible badge confirming it. Version 2.2.0: • Added a comprehensive PDF Utility (view, merge, split, convert to images, annotate). • Registered Dev Passa as a default file handler for .json files. • Vendored local libraries for faster, secure, offline-capable processing. Version 2.1.0: • Introduced Parquet Viewer (schema view, pagination, search/filter, cell-copy, export to JSON/CSV). Version 2.0.0: • Major update expanding the extension into a complete developer toolkit. • Added Text Compare (Diff tool). • Improved Timestamp Converter and expanded Encoding/Crypto capabilities. • Added Spring Boot cron expression support.
