Password Converter: Hex, Binary, Base64

Convert a password to its UTF-8 bytes as hex, \x escapes, binary, decimal, Base64, Base64URL or percent-encoding, and decode those formats back.

Direction

Password

The password is first converted to UTF-8 bytes; every format shows those same bytes. Encodings are reversible and are not encryption or hashing.

What is Password Converter (Hex/Binary/Base64)?

This converter shows the exact UTF-8 bytes of a password in seven common notations at once, and converts any of them back to text. It helps when a configuration file, API or debugging session needs the password as bytes instead of text.

How to use Password Converter (Hex/Binary/Base64)

Choose the Direction: password → encodings or encoding → password.
For encoding, type the password; every format appears with a copy button.
For decoding, choose the Input format and paste the encoded value.
Copy the result you need.

When to use Password Converter (Hex/Binary/Base64)

Use it for configuration that expects hex or Base64 secrets, for checking how non-ASCII characters are stored, or for debugging authentication headers. Remember that these encodings are not encryption: anyone can decode them.

How Password Converter (Hex/Binary/Base64) works

The password is encoded to UTF-8 with TextEncoder. Hex writes each byte as two hex digits, the \x form prefixes each byte, binary uses 8 bits per byte, decimal lists byte values, Base64 follows RFC 4648 (Base64URL uses - and _ without padding), and percent-encoding escapes every byte. Decoding reverses the format and rejects bytes that are not valid UTF-8.
