Encode HTML-sensitive characters and supported symbols as named character references. Follow the exact input and settings below to reproduce this example. Open HTML Encode.
Prepare the source text
Open HTML Encode and choose Write or paste text, or upload a supported UTF-8 text file. The upload opens the editor; it does not run the tool. This example uses the exact source shown in the comparison.
Maximum input and result: 1 MB of UTF-8 text, with a 1,048,576-character input ceiling. Expanding transformations must also fit the result limit.
Use the exact example input
<p>Café & tea</p>
This text operation runs in your browser; its source and result are not sent for conversion. A draft may be kept in this browser tab when session storage is available. Clear removes the current draft; download important work before closing the tab.
Check how the tool works
This tool has no extra transformation options to set. Keep the source exactly as shown to compare the result.
Angle brackets, ampersands and quotation marks are encoded, along with characters recognized by the tool's entity mapping. Unmapped characters remain unchanged. This broader conversion differs from HTML Escape, which focuses on the five markup-sensitive characters.

Apply and inspect the result
Select HTML Encode when the input and settings are ready. In the saved example, the result begins: "<p>Café & tea</p>".
This prepares text content; it is not a complete HTML sanitizer or a substitute for context-aware escaping in application code.
Inspect the entity strings in the monospaced result and compare input and result UTF-8 byte sizes in Result overview. A larger byte total can be expected when a single character becomes a longer entity reference.
Result overview distinguishes changed, unchanged and empty results. An unchanged result means the selected operation did not alter the text; an empty result can be the expected outcome of removal or extraction. Open Show spaces and tabs to reveal spaces as ·, tabs as ⇥ and line endings as ↵. These marks are only a preview; copied and downloaded text keeps its actual whitespace. The whitespace preview shows at most 12,000 Unicode code points. This preview limit does not shorten the editable result or its TXT download.
Save the version you reviewed
Review the current result, then use the download icon to save a TXT file. The actual download in this example is named html-encode.txt. Copy and download use the current result, so make any final wording changes before saving. Continue to can carry the result into a compatible next tool, where you review it before running another operation.
Editing the result hides the calculated details until you run the tool again. Copy and TXT download use the edited text; return to the source and reapply the tool to refresh the report.
