Base64 to Hex Converter

Base64 and hexadecimal are two of the most common encoding schemes in computing. Base64 is widely used in email attachments, JWTs, and data URIs, while hex is the go-to representation for binary data in debugging, cryptography, and network protocols. This tool lets you instantly convert in both directions — paste a Base64 string to get its hex equivalent, or enter hex bytes to recover the Base64 form. The converter handles padding automatically and shows the raw decoded text when the bytes are valid UTF-8. Use it when inspecting TLS certificates, debugging binary protocols, or verifying cryptographic hashes. Errors such as invalid characters or odd-length hex strings are reported inline so you can correct them without guessing.
