Encoding transforms data into a specific format for safe transmission, storage, or display. Developers constantly need to encode binary data as Base64 for APIs, percent-encode special characters in URLs, or convert HTML special characters to entities to prevent XSS. These tools provide instant, bidirectional encoding and decoding — type or paste your input and get the result in real time. All processing uses standard Web APIs (btoa/atob, encodeURIComponent, DOMParser) and runs entirely in the browser.
