A Base64 tool helps you encode or decode text and files using the Base64 format—a way to represent binary data in plain text. It's used in email attachments, data URLs, and web APIs.
Whether you're working with image data, JSON APIs, or debugging encoded strings, this Base64 tool gives you an instant, secure way to convert between formats. Encode files, decode strings, or just copy clean output without any fluff.
No logins. No trackers. No delays. This tool runs entirely in your browser and is built with the same performance-first, privacy-conscious approach that drives the Copyber ecosystem.
