Onetime Fax charges $5 for up to 100 pages. Larger documents are billed at $0.05 per additional page. See the [pricing page](/pricing). Can I send an international fax? Yes. Enter the full international number with a country code (for example: +44 for the UK). Pricing is the same as domestic. See [international faxing](/blog/send-international-faxes) and the [country codes list](/blog/international-fax-country-codes). Is online faxing secure? It can be. Use a reputable service with encryption in transit, verify the recipient number carefully, and avoid public Wi‑Fi for sensitive documents. For deeper guidance, see [fax security](/blog/how-secure-are-faxes). Do I need my own fax number to send a fax? No. To send a fax you only need the recipient’s fax number. If you need to receive faxes, Onetime Fax offers a [virtual fax number](/virtual-fax-numbers) for $10/month. Does Onetime Fax store my documents? Customer files are automatically deleted 1 day after the fax is delivered. For sensitive documents, review our [privacy policy](/legal/privacy-policy) and delete local copies after sending. What file formats are supported? You can upload PDF, JPG, JPEG, PNG, TIF, and TIFF files. PDF is still the most reliable format for faxing. Do I get delivery confirmation? Yes, you’ll receive an email confirmation when your fax is delivered (or an error if it fails). How long does it take to deliver a fax? Most faxes are delivered in about 1 minute per page. It can take longer for image-heavy documents. Can I create a cover page? Yes—Onetime Fax includes a built-in cover page generator. For regulated documents, keep the cover page minimal and avoid unnecessary sensitive data. How do I contact support? Email help@onetimefax.com. Typical response time is within 1 business day. ## Specialized Fax Guides [Medical Records HIPAA-compliant faxing for medical documents, insurance forms, and healthcare records.](/faq/medical-records)[Tax Documents Send tax forms to IRS, accountants, and tax preparers without visiting FedEx.](/faq/tax-documents)[Legal Documents Fax legal documents to lawyers, courts, and law firms without a fax machine.](/faq/legal-documents)[Phone Faxing Send faxes from your phone without downloading apps or installing software.](/faq/phone-faxing)[USCIS Faxing When USCIS accepts fax, formatting, and tips.](/faq/uscis-faxing)[SSA Faxing How to fax Social Security documents securely.](/faq/ssa-faxing)[International Faxing Number formatting, country codes, timing, and common destinations.](/faq/international-faxing) ## Legal Faxing [California Courts Fax filing policies, formatting, and timing.](/faq/courts-california)[Texas Courts Fax filing policies, formatting, and timing.](/faq/courts-texas)[New York Courts Fax filing policies, formatting, and timing.](/faq/courts-new-york)[Florida Courts Fax filing policies, formatting, and timing.](/faq/courts-florida) ## DMV Faxing [California DMV When fax is accepted, formatting, best practices.](/faq/dmv-california)[Texas DMV When fax is accepted, formatting, best practices.](/faq/dmv-texas)[New York DMV When fax is accepted, formatting, best practices.](/faq/dmv-new-york)[Florida DMV When fax is accepted, formatting, best practices.](/faq/dmv-florida)[Illinois DMV When fax is accepted, formatting, best practices.](/faq/dmv-illinois)
