JS Encode (CharCode/Base64/Escape)
Free online JS encoder tool, CharCode/Base64/JJencode supported
JavaScript Encoding Methods
This tool encodes JavaScript using various methods: CharCode encoding converts each character to its numeric code, Base64 encoding converts the source to Base64, Escape encoding uses escape sequences, and JJencode creates an obfuscated version using only specific characters.
How to Encode JavaScript
Paste your JavaScript source code. Select an encoding method. The tool produces an encoded version that can be decoded back. Use this for studying encoding techniques and understanding how JavaScript obfuscation works.
▶Is JavaScript encoding the same as encryption?
No. Encoding transforms code into a different representation that can always be reversed. Encryption uses a secret key to protect data. Encoded JavaScript provides no real security.
▶What is JJencode?
JJencode is an obfuscation technique that represents JavaScript using only the characters $, _, +, !, (, ), [, ], {, and }. The result is unreadable but still executes as valid JavaScript.
▶Can encoded JavaScript be decoded?
Yes, all encoding methods are reversible. This tool can decode what it encodes. Any encoded JavaScript can be decoded by examining the eval() call or decoding routine.
