Online Developer Tools & Code Utilities
Format JSON, validate payloads, encode Base64, and decode URLs with zero risk of leaking private API keys or payloads.
JSON Formatter
Beautify, pretty-print, and minify JSON payloads directly in your browser with zero risk of exposing confidential API data or tokens.
JSON Validator
Verify that your JSON strings strictly conform to RFC 8259 with instant error pointing and syntax breakdown locally.
Base64 Encoder
Encode text strings and binary files (images, audio, documents) into Base64 and Data URLs directly in your browser.
Base64 Decoder
Decode Base64 strings back to readable UTF-8 text, preview decoded images, or download binary files directly in your browser.
URL Encoder / Decoder
Encode and decode URLs, query strings, and parameters with percent-encoding and component parsing directly in your browser.
Why Use TrendWala Developer Tools?
Engineers handle sensitive tokens, production payloads, and proprietary data daily. Public online formatting websites that send payloads to remote servers represent severe security hazards. TrendWala Developer Tools execute entirely client-side, guaranteeing that your proprietary schemas, Base64 payloads, and URLs are never seen by third parties.
Zero Payload Leakage
Safely format proprietary JSON payloads, API responses, and authentication tokens without sending them across the wire.
Precise Error Highlighting
Identify invalid JSON syntax instantly with exact line, column, and token error diagnostics.
Binary & File Base64 Support
Encode and decode raw strings, images, and binary files to and from Base64 data URLs.
Deep URL Parsing
Deconstruct complex URLs into protocol, domain, path, and an editable query parameter key-value table.
Frequently Asked Questions
Yes, 100%. Open your browser developer network tab and verify for yourself: not a single byte of your JSON is ever transmitted over the network.
Yes! Our Base64 encoder and decoder properly handle UTF-8 Unicode strings as well as binary file data URLs.
