About

BaseX is a privacy-first Base encoding and decoding toolkit that runs entirely in your browser. It supports Base64 (including URL-safe and padding variants), Base32 (RFC, Crockford, hex alphabet, and more), Base58 (Bitcoin, XRP, Monero, Flickr, and Base58Check with SHA-256 verification), and Hex/Base16. You can encode or decode text, raw hex bytes, or small files up to 2 MB. Every operation is saved to a per-tool history so you can revisit past results. The app is available in 4 languages, automatically matched to your browser, and works fully offline after first load.
