Question 1

What hex format does this tool accept?

Accepted Answer

Enter hex pairs as continuous strings (DEADBEEF), space-separated pairs (DE AD BE EF), or with 0x prefixes (0xDE 0xAD 0xBE 0xEF). The tool normalizes input before decoding.

Question 2

Why does my hex output show question marks or strange symbols?

Accepted Answer

This happens when hex values correspond to non-printable control characters or to byte sequences that are invalid in UTF-8. Try switching to a different encoding (Latin-1, Windows-1252) if the source data is from a legacy system.

Question 3

Can I use this to decode hex-encoded file contents?

Accepted Answer

Yes for text files. Paste the hex representation of a text file to recover the original content. For binary files (images, executables), decoding to 'text' will produce garbled output — binary files contain non-text bytes that do not map to readable characters.
