Encoding Tools
Encoding changes how text is represented for transport or embedding; it does not encrypt it. This collection covers Unicode-safe Base64, Base64URL, URL components, and HTML entities.

Encoding ToolsBenefits
- Prepare text for URLs, tokens, HTML, and data exchange
- Decode unfamiliar values without transmitting their contents
- Handle Unicode text consistently through UTF-8 conversion
When to use these tools
- Debugging URL parameters and API payload fields
- Inspecting Base64 or Base64URL token segments
- Displaying reserved HTML characters as plain text
Common mistakes
- Assuming encoded text is secret or encrypted
- Using standard Base64 where a URL-safe alphabet is required
- Decoding HTML entities directly into executable markup

Encoding Tools FAQ
Is encoding the same as encryption?
No. Encoding is reversible representation and provides no confidentiality or authentication.
Do these encoders support Unicode?
Yes. Text is converted with UTF-8-aware browser APIs before binary encodings are applied.
Will decoded HTML be rendered?
No. Decoded HTML entities are displayed as plain text rather than inserted as active HTML.
