Base64 Encoder Decoder

Encode and decode Base64 text directly in browser.

Developer & Network

Base64 Encoder Decoder is for safely converting plain text or binary text blobs into Base64 and back. It is useful when testing APIs, email payloads, and data URIs where raw characters can break transport. Use encode mode to transform input into a portable Base64 string, and decode mode to inspect what an existing payload actually contains. This tool helps you verify round-trip correctness quickly without writing helper scripts.
