How to use Convert Integers to HTML Entities
- 1. Paste the integers. Enter one or more integers, one per line or separated by spaces. Each digit of every integer is encoded as its own HTML numeric entity.
- 2. Choose Decimal or Hexadecimal entities. Pick Decimal for entities like 1, or Hexadecimal for entities like 1, depending on which numeric character reference format your target document or template expects.
- 3. Copy the encoded entities. Copy the resulting entity string and paste it into HTML source, a template, or anywhere digits need to be escaped as numeric character references.
When to use Convert Integers to HTML Entities
Convert Integers to HTML Entities escapes every digit of a number into an HTML numeric character reference, in either decimal or hexadecimal form. Use it when a page or email template needs digits represented this way instead of as plain characters.
- Escaping numbers to defeat simple scrapers. A page displays phone numbers, prices or reference codes and encoding the digits as HTML entities makes them slightly harder for basic scrapers to extract as plain text.
- Testing an HTML entity decoder you built. You are writing code that decodes numeric character references and want known-good encoded inputs, like 12 for 12, to use as test fixtures.
- Matching an email template's encoding requirements. Some email rendering engines require numbers to be entity-encoded to render correctly across clients. Generate the entity form of a number before inserting it into the template.
- Demonstrating decimal versus hexadecimal entities. A tutorial on HTML character references shows the same digit encoded both ways. Toggle between Decimal and Hexadecimal here to generate both forms for the same integer.

About the Convert Integers to HTML Entities tool
Convert Integers to HTML Entities runs as plain JavaScript in your browser tab, with no server behind it. Encode each digit of an integer as an HTML numeric entity. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Integer Tools section, 133 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Entity format setting, and the result refreshes the moment you change it. 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.
