What encoding formats does Encoding Explorer support?

Encoding Explorer supports Base64, URL encoding (percent-encoding), HTML entities, Unicode escapes (\uXXXX), Hexadecimal, Binary, and SHA-256 hashing. All formats are generated simultaneously as you type.

Is my data safe when using this tool?

Yes! All encoding and decoding happens entirely in your browser using JavaScript. No data is ever sent to any server. You can even use this tool offline once the page is loaded.

Can I decode encoded text back to the original?

Yes — for reversible encodings (Base64, URL, HTML entities, Unicode escapes, Hex, Binary), you can toggle to decode mode and paste the encoded text to get the original back. SHA-256 is a one-way hash and cannot be reversed.

What is the difference between encoding and hashing?

Encoding is reversible — you can convert text to Base64 and back. Hashing (like SHA-256) is a one-way function that produces a fixed-length fingerprint. You cannot recover the original text from a hash.
