Benefits

Private by design

Your text stays on your device while HTML Encoder works. HTML Encoder never sends it to a server, so confidential work stays confidential.

Instant results

There is no upload step, so HTML Encoder starts the moment you add your text.

No signup, no limits

Use HTML Encoder as many times as you want. HTML Encoder asks for no account, adds no watermark and keeps no paid tier gating the output.

Works offline

Once the page has loaded, HTML Encoder keeps working without a connection, which helps on flights and locked-down networks.

Who it is for

For students

Students use HTML Encoder to hand in coursework without installing software: encode special characters to HTML entities on a shared or locked-down machine.

For freelancers

HTML Encoder helps freelancers send client deliverables quickly, since your text never leaves the laptop it was created on.

For legal and finance teams

HTML Encoder helps legal and finance teams handle sensitive documents quickly, since your text never leaves the laptop it was created on.

How it works

HTML Encoder loads your text into memory, applies the change you requested to the underlying data rather than to a screenshot of it, and writes a fresh copy for download. Your original stays untouched on disk, and every step of HTML Encoder happens inside your browser sandbox.

Frequently asked questions

Is HTML Encoder free to use?

Yes. HTML Encoder is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.

Does HTML Encoder upload your text to a server?

No. HTML Encoder processes your text inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.

Is there a file size limit?

The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in HTML Encoder.

Do I need to install anything to use HTML Encoder?

No installation is needed. HTML Encoder runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.

Can I use HTML Encoder on a phone or tablet?

Yes. The HTML Encoder interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.

What happens to your text when I close the tab?

It is discarded. HTML Encoder keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
