Encoding Tools

Encode and decode text the way developers actually need to

Base64, URL, HTML entities, hex, Unicode escapes, and gzip — the everyday text transformations for debugging APIs, payloads, and markup, entirely in your browser.

Base64 Encode/Decode

Convert text to and from Base64, with correct UTF-8 handling.

URL Encode/Decode

Percent-encode or decode a query string, path segment, or full URL.

HTML Entity Encode/Decode

Escape or unescape HTML entities like &, <, and '.

Hex ↔ Text Converter

Convert text to hexadecimal bytes and back, for byte-level debugging.

Unicode Escape/Unescape

Convert text to \uXXXX escapes and back, including emoji and surrogate pairs.

Gzip Compress/Decompress

Compress text with gzip or deflate, or decompress a Base64-encoded blob.
