Up to what number does this converter work?

We support standard Roman numeral conventions up to 3,999 (MMMCMXCIX).

Is it safe to use Edita for sensitive files?

Absolutely. Edita processes all your files locally in your browser using WASM (WebAssembly) technology. Your documents never leave your device and are never uploaded to our servers, ensuring total privacy.

Does Edita store my data or file history?

No. We have a strict 'no-storage' policy. Once you close your browser tab, all traces of your processed files are gone. We don't track your content or keep any logs of your file data.

Why is Edita faster than other online converters?

Traditional tools require you to upload large files to a server, wait for processing, and then download them back. Edita eliminates all network lag by processing everything instantly on your own hardware.
