Encoders & Decoders

Encode and decode data between formats. — 3 tools available.

Encoding tools convert data between representation formats used across web development, cryptography, and data transfer. Base64 encoding is required for embedding binary data in JSON or sending attachments over email protocols. URL percent-encoding is needed for query string values that contain special characters. Cryptographic hashing lets you verify data integrity or check passwords without storing plaintext. Every encoder and decoder here runs entirely in your browser using standard Web APIs — your data never leaves your device.
