Conversions happen in real time as you type. No waiting, no loading spinners, no server round-trips.

What is Encoding?

Encoding is the process of converting data from one format to another. Unlike encryption, encoding is reversible and not meant to keep data secret—it's about making data compatible with different systems.

Common Encoding Formats

  • Base64: Represents binary data using 64 ASCII characters. Widely used in email attachments, data URIs, JWTs, and API payloads.
  • Hex (Hexadecimal): Represents each byte as two hex digits (0-9, a-f). Common in cryptographic hashes, color codes, and debugging.
  • Binary: The raw 0s and 1s representation. Useful for understanding data at the lowest level.
  • URL Encoding: Encodes special characters for safe use in URLs using percent-encoding (e.g., %20 for space).

Why use this tool?

Developers frequently need to encode and decode data when working with APIs, debugging network requests, handling authentication tokens, or inspecting binary data. This tool lets you do all of that in one place without leaving your browser.

Encoding vs. Encryption

  • Encoding transforms data for compatibility. Anyone can decode it—there's no secret key involved.
  • Encryption transforms data for confidentiality. Only someone with the correct key can decrypt it.
  • Never use Base64 for security. It's trivially reversible. If you need to share secrets securely, use SnapPwd's encrypted sharing.

Need to share encoded data securely?

Base64 is not encryption. If you need to share sensitive data, use SnapPwd's end-to-end encrypted, self-destructing links.
