📋 When to Use the Currency Converter
The Currency Converter is ideal when you need to convert between formats or units quickly — whether you're reformatting data for a different tool, preparing content for a client, or just trying to make sense of incompatible file types. Use it when working remotely without access to desktop software, when sharing screens in a meeting and need a fast conversion, or when you want to avoid uploading sensitive files to unknown servers. Everything processes in your browser for maximum privacy.
⚙️ How the Currency Converter Works
The Currency Converter processes your input using conversion algorithms that run entirely in your browser. When you paste or upload content and select the output format, JavaScript parses the input, transforms it using format-specific logic (encoding, decoding, parsing, serializing), and produces the converted output. For file conversions, all processing uses browser-native APIs and JavaScript libraries loaded from CDN — your files are never uploaded to any server.

Frequently Asked Questions
Where do the exchange rates come from?
The Currency Converter fetches live exchange rates from a public API (typically exchangerate-api.com or similar). Rates update automatically when you load or refresh the page.
How often do exchange rates update?
Exchange rates are fetched when you first load the page and when you change the base currency. For the most current rates during extended sessions, refresh the page. Rates typically update every hour from the API source.
Are the exchange rates the same as what banks use?
The rates shown are mid-market rates (the midpoint between buy and sell). Banks and currency exchange services add a margin (spread) on top of these rates, so your actual exchange rate may differ by 1-5%.
Can I convert cryptocurrencies?
This converter focuses on fiat currencies (USD, EUR, GBP, etc.). For cryptocurrency conversions, use a dedicated crypto exchange rate tool that connects to crypto market APIs.
