Encoding tools

Base64, URL encoding, HTML entities and the encoding lab—client-side only.

• Base64 Encode / Decode — Encode or decode Base64 text entirely in your browser with LocalKit. Handy for data URLs and tokens—processing stays on-device with nothing uploaded for computation.
• URL Encode / Decode — Percent-encode or decode URL components locally in LocalKit. Prepare query strings and path segments without sending text to a remote encoder or creating an account.
• HTML Entities — Encode or decode HTML special characters locally in LocalKit. Prepare safe snippets in your browser—text stays on-device with nothing uploaded for computation.
• Encoding Lab — Convert among hex, Base64, URL encoding and UTF-8 byte views in LocalKit. Inspect encodings locally—bytes stay on-device with nothing uploaded for computation.
• Gzip Tool — Compress or decompress text with browser CompressionStream (gzip) in LocalKit. Pack payloads locally—content stays on-device with nothing uploaded for computation.

All listed tools run in your browser. LocalKit does not upload content for computation.
