What You Can Do In This Category
Encoding and decoding tools are useful for inspecting payloads, preparing data for transport, and understanding how text or binary content is represented across systems.
This category serves developers troubleshooting APIs, URLs, headers, auth flows, and browser or backend integrations where encoded values need quick inspection.
Common Workflows
- Encode or decode Base64, URLs, and HTML entities during debugging
- Inspect payloads copied from browser tools, logs, and API clients
- Prepare values for transport-safe use in requests, embeds, and config files
Base64 Encode / Decode
Encode text or files to Base64 and decode Base64 strings back to text. Supports Unicode and binary data.
URL Encode / Decode
Encode and decode URLs and query parameters. Handles percent-encoding for safe URL transmission.
HTML Entity Encode / Decode
Convert HTML entities like & < > to their escaped forms and vice versa.
JWT Decoder
Decode and inspect JWT tokens. View header, payload, and signature without verification.
Unicode Escape / Unescape
Convert Unicode characters to escape sequences and back. Supports \u and \U formats.

Category FAQ
Are encoding tools the same as encryption?
No. Encoding is meant for representation and transport, while encryption is meant for secrecy and security.
Why use an online encoder for developer work?
It is useful for one-off checks when you want to verify a value quickly without writing a script or opening another app.
