مبدل ارز آنلاین رایگان - نرخ‌های زنده 2024

On the homepage type the number in the Amount box, pick the source currency in the 'From' dropdown and the target currency in the 'To' dropdown (you can type a currency code like USD or EUR to jump to it). Results update as you type or when you press the blue Convert button; use the double-arrow Swap button to reverse the pair. The page shows the rate timestamp (e.g., Rates updated: 2024-07-10 14:23 UTC) and a Refresh rates button to force a new fetch. For precision change the Settings (gear) to 2–6 decimal places; no signup is required for immediate use.

Rates are pulled from upstream financial feeds and refreshed on the site every 60 seconds by default; you can force an immediate update with the Refresh rates button. If you leave the page open the browser polls the server once per minute; background tabs (particularly Safari on iOS) may be throttled and stop auto-refreshing. Each conversion shows a timestamp and source name (e.g., ECB / commercial feed) so you can tell how recent the rate is. The free service applies a 60-requests-per-minute rate limit per IP to prevent abuse.

Currency Converter Online Free supports 170+ fiat currencies (USD, EUR, GBP, AUD, JPY, etc.) and the top 12 cryptocurrencies (BTC, ETH, LTC, etc.). The Amount field accepts integers and decimals with up to six decimal places and a maximum value of 1,000,000,000 (one billion); use plain digits only — commas are accepted but stripped on submit. Currency codes follow ISO 4217; you can paste codes or full names into the drop-down search. If you need exotic or very small units (micro-units), export the rate to CSV for external high-precision processing.

Yes — use the Export button beneath the results panel to download either the last 1,000 conversions as a UTF-8 CSV (.csv) or a spreadsheet (.xlsx), or request a machine-readable snapshot in JSON (.json) via the Export menu. Downloads are performed through your browser download folder; .csv uses comma delimiter and UTC timestamps, and Excel may prompt you to convert text to numbers when opening. For printing, use the browser Print dialog (Ctrl/Cmd+P) to save a PDF; large export files (>1,000 rows) are blocked — split by date range if needed.

The web tool is free to use without creating an account and there are no watermarks on exported CSV/XLSX/PDF files. That said, the free tier has practical limits: 60 automatic refreshes per minute per IP and up to 1,000-export rows; there is no SLA or uptime guarantee. There is no API key for the public JSON export endpoint — it is rate-limited to the same 60 requests/min per IP. For guaranteed uptime or higher quotas consider a paid enterprise data feed (not part of the free site).

The most frequent messages are 'Network error', 'Rate not available for pair', and 'Rate update failed'. For Network error first check your internet and disable ad/blocking extensions that can block the external API domain (look for console CORS errors). For 'Rate not available' the tool doesn't support outdated or very-local currencies — try a nearby major currency or export a JSON snapshot for manual calculation. If numbers reject due to formatting, clear non-numeric characters or set decimal precision in Settings to accept the input.

Yes. Safari on iOS pauses JavaScript timers in background tabs so auto-refresh stops; press Refresh rates when returning to the tab. Chrome and Firefox fully support polling and the Export features, but very old Internet Explorer is unsupported (use Edge or modern Chromium builds). On desktop Chrome, large long-running sessions (thousands of conversions) may consume memory — reload the page every few hundred conversions to clear memory. Also, some corporate networks block the API domain; try a different network or inspect network console for blocked requests.

The site fetches live rates from upstream providers and displays them; it does not require sign-up and does not persist personal amounts or conversion history on the public servers for the free flow. Non-identifying telemetry (aggregate usage counts, anonymous error logs) may be collected to maintain the service. Exports you download (CSV/XLSX/JSON) are generated on the server at request and delivered to your browser; nothing in those files is uploaded back to the site unless you explicitly use a share feature. If you need local-only processing, export the JSON and handle it in local tools.

The site displays mid-market/live exchange rates — for example if USD→EUR mid-rate is 0.912345 the tool will show that mid-market figure and its timestamp. Banks and card issuers typically add a margin (commonly 0.5–3% depending on provider) and may use an intra-day rate, so the price you actually pay will usually be worse than the shown mid-rate. For wire transfers and FX trades always request a firm quote from your bank or broker; use the tool to quickly find the market midpoint and then compare with provider fees and spreads.

Yes — use the public JSON export URL pattern shown in Settings (for example: https://currencyconverter.example.com/api/latest?base=USD&symbols=EUR,GBP). In Google Sheets you can fetch JSON with a script or use IMPORTDATA for CSV exports (paste the CSV export URL). The free endpoint is unauthenticated but rate-limited to 60 requests per minute and 500 requests per day; if you exceed limits you’ll see HTTP 429 responses. For high-frequency or production use, export CSV snapshots periodically or use a paid data provider; Excel's Power Query can also import the .csv or .json files directly.

Switch the Settings gear to 4–6 decimal places before converting large sums to reduce rounding error, and export the raw JSON for programmatic reconciliation. For large transfers compare the timestamp on the rate with your bank’s quoted timestamp; if the difference is more than a minute you should request a live quote from your provider. The tool is great for quick mid-market checks, but desktop apps like Excel or financial terminals (Bloomberg, Reuters) are better for bulk automated workflows and audit trails — use exported .xlsx when you need an editable ledger.

For USD→EUR type the amount (e.g., 1,000) into Amount, select USD in 'From' and EUR in 'To' — the page will show the converted amount immediately (for example 1,000 USD → 912.35 EUR if the current mid-rate is 0.91235). For GBP→AUD use the same flow: enter amount, select GBP and AUD, then press Convert or read the live result. Use the Copy icon next to the result to copy numeric value to clipboard, and press Export to save the rate and timestamp to CSV/XLSX/JSON for records; remember rates change, so note the displayed timestamp when recording a conversion.
