HTML entities let text contain characters like `<`, `>`, and `&` without the browser treating them as markup.

The [HTML Entities](/tools/html-entities/) tool helps with the mechanical part, but I still check the result before using it somewhere real.

## The simple idea

HTML entities let text contain characters like `<`, `>`, and `&` without the browser treating them as markup.

I use the tool to make the transformation visible: input on one side, output on the other, and a quick sanity check before I copy anything.

## Step 1: Paste the text that may contain HTML special characters

Paste the text that may contain HTML special characters.

## Step 2: Escape it before placing it in an HTML context

## Step 3: Check that `<script>` appears as text, not executable markup

Check that `<script>` appears as text, not executable markup.

## Step 4: Unescape only when you intentionally want the original characters back

Unescape only when you intentionally want the original characters back.

## Step 5: Do not use entity escaping as the only security layer for every context

Do not use entity escaping as the only security layer for every context.

## Step 6: Remember that HTML, JavaScript, CSS, and URL contexts have different escaping rules

Remember that HTML, JavaScript, CSS, and URL contexts have different escaping rules.

## Step 7: Prefer framework escaping defaults when building real apps

Prefer framework escaping defaults when building real apps.

## My checklist

Before I trust the result, I check:

- Paste the text that may contain HTML special characters.
- Escape it before placing it in an HTML context.
- Check that `<script>` appears as text, not executable markup.
- Unescape only when you intentionally want the original characters back.
- Do not use entity escaping as the only security layer for every context.
- Remember that HTML, JavaScript, CSS, and URL contexts have different escaping rules.
- Prefer framework escaping defaults when building real apps.

Small utilities are useful because they remove repetitive work. They are safest when the output is still reviewed.
