Frequently Asked Questions
What can I encode and decode here?
You can run Base64 encode/decode and URL encode/decode operations on text values.
Can this help with API debugging?
Yes. It is useful for testing query parameters and encoded payload values.
Is encoded data uploaded anywhere?
No. All encoding and decoding happens in-browser.
Example input/output
Input: 48 65 6c 6c 6f

How it works
This tool splits the hex input on spaces (or processes it in 2-character chunks), parses each value with parseInt(chunk, 16), and converts to a character using String.fromCharCode(). Processing runs in your browser.
Common use cases
- Decode hex-encoded strings from network captures or log files
- Convert hex byte sequences to readable text during security analysis
- Inspect hex-encoded data from protocols that use hex encoding
