HTML entities are escaping, not sanitization. They help reserved characters display as text, but they do not make unsafe HTML safe to render.
Quick answer
HTML Entity Encoder / Decoder generates encoded or decoded HTML entity text from text or HTML snippet, entity input, mode, quote handling and non-ASCII option. The visible generation method is Output = replace reserved HTML text characters with named or numeric character references, or reverse valid references to Unicode text.

Details
These notes make the assumptions explicit, especially where the same search query can mean slightly different things.
The encoder escapes ampersands, angle brackets, and optional quote characters so text can appear inside HTML safely as text.
The decoder supports common named entities plus decimal references like © and hexadecimal references like ©.
Escaping text is useful, but rendering untrusted HTML still needs a real sanitizer and careful framework handling.

Benchmarks
This generator is a drafting aid, not a fixed rule. Use the output to compare options and document your assumptions. Benchmark ranges are broad planning heuristics unless this page names a specific source for the range.
Escape ampersands first when converting text to HTML entity form.
Useful when code or tags should be displayed instead of interpreted as markup.
Decimal and hexadecimal numeric references can represent Unicode code points.
Method and limitations
The generation method, inputs, example, and limitations are shown so the draft output is checkable, not treated as final copy.

FAQ
No. Entity encoding helps reserved characters display as text. Sanitizing HTML is a broader security process for untrusted markup.
Encode quotes when text may be placed inside HTML attributes. For normal text nodes, escaping ampersands and angle brackets is usually the main requirement.
Yes. It decodes decimal references such as © and hexadecimal references such as © when they point to valid Unicode text.
Use the page notes for each tool. Browser-side utilities can generate outputs locally, but the final file or code may still reveal whatever you encode or share.
Scanners, printers, file viewers, apps, and platform previews can behave differently, so test the exact downloaded output before using it publicly.
Different tools may use different rounding, assumptions, default rates, methods, formulas, or input timing. Compare the visible method and inputs before relying on the output.
