HTML Entity Encoder / Decoder

Transforms ampersands, angle brackets, quotes, and numeric Unicode entities in-browser. Decoding returns text and never executes HTML. Encoding alone is not context-aware XSS protection.

FreeNo accountIn-browser
01
Processing boundary

Input is processed only in the active browser tab's memory and is not sent to a ByteQuant server.

02
Persistent storage

Input and output are not stored. The optional usage counter keeps only tool identity and count, never content.

03
Verification

Output comes from disclosed rules or browser APIs and needs independent review before high-impact use.

HOW TO USE IT

A result in three steps

  1. 01

    Enter text and choose encode or decode.

  2. 02

    Run the conversion and compare character counts.

  3. 03

    Use context-appropriate automatic escaping in production templates.

GOOD USE CASES

When is this tool useful?

  • Displaying code inside HTML
  • Reading entity-encoded content
  • Pre-checking template escaping
Important limitation

Automated output is a preliminary assessment. Do not use it alone for legal, financial, medical, or security-critical decisions.
