How to use Convert Unicode to HTML
- 1. Paste the text to entity-encode. Paste the Unicode text you want converted to HTML entities. Every character is read and matched to its numeric character reference before being written back out.
- 2. Choose the Entity format and scope. Choose Entity format as decimal like π or hexadecimal like π, and turn on Only encode non-ASCII characters to leave ordinary letters and punctuation untouched while entity-encoding everything else.
- 3. Copy the entity-encoded string. Copy the entity-encoded string and paste it into raw HTML, an XML document, or anywhere the surrounding system only safely accepts ASCII characters.
When to use Convert Unicode to HTML
Convert Unicode to HTML rewrites characters as numeric HTML entities so they survive systems that mangle raw UTF-8. It is the fix when a CMS, template engine, or old email client strips or corrupts special characters unless they arrive as entity references.
- Fixing mojibake in a legacy CMS. An old content management system keeps corrupting accented characters or curly quotes on save, and entity-encoding the non-ASCII characters before pasting sidesteps whatever charset bug the CMS has.
- Embedding a symbol in an email template. An HTML email needs a trademark or currency symbol to render correctly across clients with inconsistent charset handling, and numeric entities are the most portable way to guarantee that.
- Writing safe XML content. An XML document or RSS feed needs special characters escaped as numeric entities to stay valid, and encoding only the non-ASCII characters keeps the rest of the markup easy to read.
- Documenting a symbol for a style guide. A design system's documentation needs to show both the visual character and its exact HTML entity code so developers can copy the correct reference into markup.

You can shape the output with 2 settings, including Entity format and Only encode non-ASCII characters, and the result refreshes the moment you change one. 2 worked examples further down the page show exactly what the tool produces for real inputs.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
