Om dette verktøyet
Encode special characters as HTML entities (&, <, ☃) or decode entity-encoded text back to plain Unicode. Includes a per-character Unicode inspector showing code point, UTF-8 bytes and JavaScript escape sequences.
Useful for safely embedding reserved characters in HTML/XML, debugging escaped content from APIs, exploring Unicode characters, and building copy-paste-safe code samples. Runs locally in your browser.
HTML entities exist so characters with special meaning in HTML (<, >, &, ", ') can appear safely inside markup, and so non-ASCII characters can survive transports that mangle UTF-8. Privvert converts both named entities (&, ©, €) and numeric entities (©, é) in both directions, with full support for emoji and astral-plane Unicode characters.
Funksjoner
- Encode as named, decimal or hex entities
- Decode every form of HTML entity
- Per-character table: code point, UTF-8 bytes, JS escape (\u, \x)
- Round-trip safe - encode then decode returns the original
- Browser-only - text never uploaded
- Free and unlimited
Slik bruker du det
- Paste text.
- Pick an encoding style (named, decimal or hex).
- Copy the encoded or decoded result.
- (Optional) inspect each character in the breakdown table.

Ofte stilte spørsmål
They let you safely include reserved HTML characters (<, >, &, ") in markup without breaking it. Entity-encoded text always renders as the literal character, never as markup.
Named (&) is most readable. Decimal (&) and hex (&) are universally supported and work for any Unicode character. Use named for the common ones, hex/decimal for everything else.
Most modern setups use UTF-8 throughout, so most characters can be written literally. Entities are still essential for the reserved characters (<, >, &, ", ') and useful for invisible characters.
When you need to put a Unicode character in a JavaScript string literal - \u00E9 for é, \u{1F600} for 😀 - these escapes work in any JS source.
Any time user-controlled text is inserted into HTML markup. Failing to encode is the canonical XSS vulnerability - a comment containing becomes executable script if rendered without encoding. Modern templating engines (React, Vue, Svelte) encode by default; raw string concatenation does not.
HTML entities encode for HTML context (& for &). URL encoding (%26) encodes for URL context. They are different escape schemes for different parsers - mixing them is a common bug.
