Troubleshooting
The file does not open
Check that it is one of the supported formats above and opens in another app. Damaged files and password-protected PDFs cannot be read until they are repaired or unlocked.
It is slow or stops on a very large file
Everything runs on your device, so speed depends on its memory. Close other tabs, use a computer rather than a phone, or split the file into smaller parts first.
The download did not start
Look for your browser’s download bar or icon. Some browsers ask once before a site may download files; allow it and click the button again.
Frequently asked questions
How accurate is this?
The calculator uses the standard formula shown on the page and rounds only for display. Real offers can differ because of fees, rounding rules or changing rates, so treat results as estimates.
Keep working with the result
