HTML Entities Encoder/Decoder — About
Understand when to use HTML versus XML entity modes, what conversions look like, and how the tool protects your clipboard-ready results.
Key points
Entity fidelity
The tool normalizes existing entities before encoding so you do not end up with double-encoded strings when sanitizing legacy content.
Client-side privacy
Everything runs locally in your browser. Share URLs embed state for collaboration, but no text ever leaves your machine unless you copy or download it.
The HTML entities encoder/decoder exists for people who wrangle markup daily. Whether you are pasting copy into a CMS, preparing transactional emails, or sanitizing user submissions, you need results that match production parsing rules. This tool keeps the workflow lightweight so you can validate snippets without leaving the browser.
Two profiles for different targets
HTML mode leans on the HTML5 entity table so familiar names like & and — stay readable. XML mode sticks to numeric references—ideal when feeding templating engines, RSS readers, or APIs that do not accept named entities.
Normalization prevents surprises
Some editors paste text that already contains entities. Before encoding, we decode everything and rebuild the output so the string remains canonical. That means & stays a single ampersand entity instead of ballooning into &.
Private, sharable conversions
Results never leave the browser, and share links base64-encode the relevant fields inside the URL. When collaborating, copy the link so teammates can reproduce the exact state without emailing files or screenshots.

How to use this tool
Step 1
What the tool delivers
Fast, deterministic conversions between plain text and entity-rich output with HTML5 and XML profiles, plus copy and download helpers.Step 2
How to integrate it
Use it when preparing content for email campaigns, RSS feeds, or static site generators where literal characters would break parsing.Step 3
Limits to remember
Very large pastes can create long share URLs. For archival workflows export the result as a file instead of relying solely on encoded query strings.
Frequently asked questions
- Does the encoder support custom numeric formats?
- Yes. XML mode always outputs decimal numeric references so strict parsers are happy, while HTML mode prefers named entities when available.
- Can I use the output in JavaScript strings?
- Entity output is HTML-focused. For JavaScript or JSON contexts consider escaping with language-specific utilities after converting here.
- Will conversions handle emoji-heavy content?
- Absolutely. Astral characters, emoji, and glyphs beyond the BMP round-trip without corruption in both modes.
Share links embed your latest conversion directly in the URL. Avoid sharing encoded payloads that contain secrets or proprietary text outside trusted channels.
