About JSON Minifier
JSON Minifier is a fast, lightweight, and 100% offline developer tool designed to compress, format, and validate JSON data instantly on your Android device.
Whether you are a software engineer, API developer, web designer, or student, JSON Minifier makes handling complex or large JSON payloads simple, efficient, and private.
⚡ PRIMARY FEATURES
• JSON Minification: Instantly compress formatted JSON by removing unnecessary line breaks, whitespace, and indentation into a single compact line string.
• JSON Beautifier \& Formatter: Convert compact JSON strings into clean, human-readable structured JSON with customizable indentation (2 spaces, 4 spaces, or Tabs).
• JSON Validator: Quickly test if your JSON payload is syntactically correct. Get precise error messages and line/column locations when syntax errors occur.
• Detailed Statistics: View real-time JSON statistics including original size, minified size, bytes saved, compression reduction percentage, character count, and line count.
• Local File Import \& Export: Import `.json` or `.txt` files directly using Android Storage Access Framework (SAF) and save your minified/formatted results safely.
• Local Processing History: Keep track of recent minification and formatting sessions with instant preview and copy options.
• Clipboard \& Sharing: Copy processed JSON with a single tap or share results directly using standard Android share sheet.
• Input/Output Swapping: Easily use your output as new input for repeated formatting and testing workflows.
• Customizable Editor: Adjust editor font sizes (Small, Medium, Large), toggle line numbers, word wrapping, and keep screen awake settings.
• Dark \& Light Theme: Full support for System Default, Dark Mode, and Light Mode for comfortable night editing.
🔒 PRIVACY FIRST \& 100% OFFLINE
Your privacy and code security are our top priority. JSON Minifier operates completely locally on your device without requiring an internet connection. Your JSON content is never uploaded, stored, or transmitted to any remote server or third party.

⚠️ DISCLAIMER
JSON Minifier is provided "AS IS" as a developer productivity utility. While every effort has been made to ensure accurate JSON parsing and formatting according to RFC 8259 standards, the developer is not responsible for any data loss, code corruption, or damages resulting from the use or misuse of processed JSON strings. Users are advised to verify critical JSON structures before deploying to production environments.
