Frequently Asked Questions
Binary / non-text?
Use Base64 for anything non-printable.
URL vs component?
Use URL-component for query parameters — it escapes `&` and `=`.
How do I use the Encoding Converter?
Simply type your numbers and read the result, which refreshes the instant you change something. There is nothing to submit and nothing to wait for.
Is it free? Does it work without internet?
Yes to both. It is free with no sign-up, and once the page has loaded it keeps working even with no internet.
Where does my data go?
Nowhere — every calculation runs on your own device. Nothing you enter is uploaded, logged, or stored.
