Send a fax from your PC using the file you already have.

If your task is to send a file from a Windows laptop or desktop, you can prepare that file locally and upload it to an online fax service. The service transmits it to the recipient's fax number. You do not need to attach a telephone line or buy a fax modem for this workflow.

Keep the destination details handy before starting. Confirm the fax number with the receiving department and check whether its instructions require a reference number, signed form, or cover page. A general office telephone number and a dedicated fax number may look similar, so do not assume they are interchangeable.

The 1Fax website supports PDF, DOCX, PNG, and JPG. If your finished document is already a PDF, open it and inspect it directly. If it is in Word, Microsoft provides PDF export through Save As or Save a Copy, with options for page ranges and markup.

A PDF copy is useful when page layout matters. Keep the editable original, then review the exported copy for tables, signatures, and page breaks. If the recipient asked for selected pages, confirm the final file contains those pages rather than the whole working document. Our Word-to-fax guide covers this preparation step.

Microsoft documents a Print to PDF route in Word: open the print dialog, choose Microsoft Print to PDF, and save the output as a file. Other applications may offer their own PDF export or Save as PDF destination. Use the option available in the app you are working in.

Read the print preview before saving. Set the intended orientation, page range, and scale, especially for wide tables. Then open the saved file to check the actual result. This creates an uploadable document; selecting a PDF printer does not send anything to the recipient's fax number.

Microsoft's Windows Scan guidance explains how to select a scanner, scan settings, and a save location. The available source and formats depend on the device. Check the saved output instead of assuming that loading several sheets captured every page or both sides.

For a two-sided application, compare the scan against the paper copy side by side. Rotate any upside-down backs and put the pages in reading order. A clean scan should preserve text near the edges, checkboxes, dates, and signatures. The double-sided fax guide gives a page-order example you can use.

Open the 1Fax send form in your browser, enter your email and the confirmed fax number, and select the final document. If it lives in cloud storage, make sure you have the actual downloaded file. A browser shortcut, ZIP archive, or cloud-document pointer is not a supported fax attachment.

Check the preview and detected total pages, including any cover sheet. For domestic sends, an eligible one-page fax can use the free offer; other sends cost $1 for up to two total pages and $0.50 for each additional page. Confirm the displayed total for your specific destination and options before authorizing payment. Paid sends are captured only after successful delivery.

Once the submission is accepted, follow its status to a final result. A document upload and a fax delivery are separate steps. Keep the fax reference and the exact file you sent so you can explain which packet belongs to which transmission.

If you cannot upload, inspect the file format, whether it opens normally, and whether its download finished. If the upload works but transmission fails, inspect the fax error and reconfirm the recipient's number or line availability. The fax troubleshooting guide separates these cases so you can avoid submitting duplicate jobs without fixing the cause.
