Frequently asked questions
Plain-language answers about when to use the tool, what it does with your inputs, what to double-check, and how privacy works.
When should I use the HTML Entity Encoder / Decoder?
Use it when your task matches one of these common needs: Show HTML code examples inside a blog post, guide, or documentation page. Decode copied entity text so it is easier to read. It works best when you already know the values, dates, units, or settings the page asks for.
What is the HTML Entity Encoder / Decoder doing with my inputs?
In plain language: Encode mode replaces &, <, >, quotes, and apostrophes with HTML entities. Decode mode converts supported named and numeric entities back to characters. The examples on the page are there so you can compare your inputs with a filled-out calculation before copying the answer.
What do the main HTML Entity Encoder / Decoder inputs mean?
The main inputs are the values, text, dates, units, or settings the tool needs before it can work. Read each field label carefully, keep units consistent, and compare your entry with the examples if the answer looks strange.
How should I read the HTML Entity Encoder / Decoder answer?
Read the output next to your original input. If the tool changes format, units, encoding, spacing, or capitalization, compare a small sample before copying the whole result into another app.
What should I double-check before trusting the answer?
Entity encoding is useful for displaying code examples as text, but it is not a complete sanitizer for untrusted HTML or script content. Also check that you used the right unit, date, scale, or mode because small input changes can change the result.
Does the site save what I enter?
