Private developer text utility

Convert HTML entities without uploading text

EntityCodec converts bounded plain text in an isolated no-network capsule. Choose readable named references or explicit numeric forms, or resolve exactly one parser layer while the result stays plain text.

No account · no upload · no rendering · no result URL

Three explicit steps

Paste, choose, inspect

01

Paste plain text

Input remains inside the isolated browser document.

02

Choose one contract

Encoding exposes format and scope; decoding resolves one layer.

03

Inspect as text

The result is never inserted as executable HTML.

Developer-focused

Useful for visible text fixtures

  • Prepare documentation examples that must show reserved HTML characters literally.
  • Compare named, decimal and hexadecimal representations of the same code points.
  • Inspect one layer of encoded text without rendering tags or scripts.
