## Common questions

### Is my input uploaded?

No. Your input is processed locally in your browser and is not sent to the server or included in analytics.

### Can I use the base64 encoder output elsewhere?

Yes. Use Copy, or Download when available, after reviewing the output.

### How do I use the Base64 Encoder?

Enter the required values for Text. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Base64 Encoder use?

Text is converted to UTF-8 bytes, then encoded using standard Base64. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.

### Can the Base64 Encoder be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- The result depends on the values you enter for this base64 encoder; it does not supply missing rates, rules, prices, dates, or assumptions for you.
