About Technical Tools

Developers and technical professionals rely on encoding, decoding, hashing, and formatting tools daily. Our technical toolkit provides browser-based utilities that keep your data private while delivering instant results.

Essential tools include JSON Formatter for debugging API responses, Base64 Encoder/Decoder for data transfer, and URL Encoder/Decoder for handling query parameters. Security-focused tools like our SHA-256 Hash Generator help with verification and authentication workflows.

Frequently Asked Questions

What is URL encoding and why is it needed?

URL encoding converts special characters into a format that can be safely transmitted in URLs. Characters like spaces, ampersands, and non-ASCII characters are replaced with percent-encoded equivalents (e.g., space becomes %20). This is essential for query strings and API parameters.

What's the difference between MD5 and SHA-256?

Both are hash functions that create fixed-length fingerprints of data. MD5 produces a 128-bit hash and is faster but considered cryptographically broken. SHA-256 produces a 256-bit hash and is currently secure for cryptographic purposes. For security-critical applications, always use SHA-256.

How do I format minified JSON?

Paste your minified JSON into our JSON Formatter tool. It will automatically parse and pretty-print the JSON with proper indentation. The tool also validates your JSON and highlights any syntax errors.
