Why the HTML Entity Encoder & Decoder is different

Browser-native

The HTML Entity Encoder & Decoder runs entirely in your browser. Input is processed locally — never uploaded, never logged, never cached anywhere outside your device.

No artificial limits

No daily quotas, no character ceilings, no "upgrade for more" walls. Every feature is the complete feature — the same on the first use as the thousandth.

Production-grade quality

Built to the same engineering bar as paid SaaS tools — accurate algorithms, audited logic, responsive design and accessibility-tested interactions.
