Free Mothereff.in HTML Entities Alternative
Mothereff.in's HTML entity encoder/decoder is a well-known open-source tool created by Mathias Bynens, a former Google Chrome engineer. It uses the 'he' library to encode and decode HTML entities with a clean, minimalist interface. The tool is completely free, has no ads, and requires no signup. However, it lacks encoding format options (you can't choose between named, decimal, or hex entities) and doesn't provide guidance on XSS prevention or when to use HTML encoding. If you need more control over encoding formats and want built-in security guidance, Fixie's HTML Entity Encoder/Decoder offers a more comprehensive solution.

Why Choose Fixie?
Mothereff.in's HTML entity encoder is an excellent tool created by a respected developer in the web standards community. It's clean, fast, and uses the robust 'he' library for accurate HTML entity handling. The minimalist design means there's zero clutter — just paste your text and get the encoded result. It's completely free, ad-free, and open-source under the MIT license, making it popular with developers who value simplicity.
However, the tool's simplicity also means it lacks some features that are useful for everyday development work. You can't choose between different encoding formats (named entities like &, decimal like &, or hexadecimal like &) — it automatically picks one for you. There's also no guidance on when to use HTML encoding or how it prevents XSS attacks, which can be confusing for newer developers.
Fixie's HTML Entity Encoder/Decoder builds on the same core functionality but adds practical features: you can choose your preferred encoding format, see explanations of what each entity means, and get built-in XSS prevention tips. If you're learning web security or need precise control over HTML encoding, Fixie provides more educational value and flexibility while maintaining the same privacy-first, no-signup approach.
How to Use HTML Entity Encoder/Decoder
Step 1: Open the HTML Entity Encoder
Go to fixie.tools/html-entity — instant access with no signup required.
Step 2: Paste Your Content
Paste the text or HTML you want to encode or decode. The tool automatically detects whether you're working with plain text (to encode) or HTML entities (to decode).
Step 3: Select Your Encoding Format
Choose between named entities (<, >, &), decimal numeric entities (<, >), or hexadecimal entities (<, >). This gives you control over the output format based on your use case.
Step 4: Copy and Use
Copy the encoded or decoded result. The tool also displays security tips to help you understand when HTML encoding is necessary for XSS prevention.
