What does an HTML entity encoder do?

It converts special characters like angle brackets, ampersands, and quotes into their corresponding HTML entity codes so browsers display them as plain text rather than interpreting them as functional HTML tags.

Why would I need to encode HTML entities?

You need to encode HTML entities when displaying raw code snippets on a webpage or securely managing user input within a web application to prevent browsers from misinterpreting characters as functional HTML.

Can HTML entity encoding prevent XSS attacks?

Encoding alone does not prevent XSS attacks, but some tools include XSS prevention analysis that offers insight into potential security issues with your encoded content.

Is it better to encode in the browser or on a server?

Encoding in the browser keeps your data private since it never leaves your device, while server-based encoding may offer additional security analysis features but requires sending your text to an external site.

What characters should I encode when working with HTML?

You should encode angle brackets ( ), ampersands (&), and quotes (" ') since these have reserved meaning in HTML structure and can cause display issues if not properly encoded.

Buyer's guide

How to choose a html entity encoder

When picking an HTML entity encoder, consider whether you need basic conversion or additional security features. If you are embedding user-generated content or code snippets, look for XSS prevention analysis. If privacy is your top concern, choose a browser-only tool that doesn't transmit your data to a server. The differences worth caring about are the presence of security analysis, privacy guarantees, and whether the tool requires an account.
