Fax from Your Computer in Any Browser
Open bestfax.com in Chrome, Firefox, Safari, or Edge. Drag and drop your document, enter the fax number, and send. Works on Windows, Mac, Linux, and ChromeOS.
Quick Answer
You can send a fax from any computer (Windows, Mac, Linux, or ChromeOS) without a fax machine or phone line. Open a web browser, go to bestfax.com, enter your name and email, enter the recipient's fax number, drag and drop your document (up to 10 files, 50MB total), optionally add a cover page, preview the fax, and pay. No software installation is required. $4.95 per fax or $10/month for unlimited.
Any Browser, Any OS
Chrome, Firefox, Safari, Edge — Best Fax works in all modern browsers on Windows, macOS, Linux, and ChromeOS. No software downloads needed.
Drag and Drop Upload
Drag your document from your desktop, file manager, or downloads folder directly into the browser window. Upload up to 10 files (PDF, Word, Excel, PowerPoint, images) totaling 50MB.
Smart Cover Pages
Add an optional cover page with your subject and message. Choose from 4 professional templates and use the AI enhance button to generate polished cover page text automatically.
Live Number Validation
As you enter the recipient's fax number, Best Fax checks whether it's a valid fax line in real time. Warnings appear for mobile or VoIP numbers before you pay.
Full Dashboard (Subscribers)
Subscribers get the full Best Fax dashboard with fax history, contact management, scheduled faxing, fax receiving, and a dedicated fax number.
Automatic Retry
If a fax fails due to a busy signal or connection issue, Best Fax automatically retries up to 6 times with intelligent protocol fallback (T.38 to G.711) at no extra cost.
How It Works
Open Your Browser
Navigate to bestfax.com in Chrome, Firefox, Safari, Edge, or any modern browser. No plugins, extensions, or software downloads required. Works on Windows, Mac, Linux, and ChromeOS.
Enter Details and Upload
Enter your name and email (no password needed for new users). Enter the recipient's fax number — Best Fax validates it in real time. Drag and drop your document or click to browse. Add an optional AI-enhanced cover page.
Preview, Pay, and Send
Review a visual preview of your complete fax before sending. Pay $4.95 for a one-time fax or subscribe at $10/month for unlimited. Best Fax transmits your document and confirms delivery by email.
The Full Fax Experience on Desktop
While Best Fax works on any device, a computer gives you the most comfortable experience. Drag and drop files directly from your desktop. See a side-by-side preview of your fax before sending. Subscribers get the full dashboard with fax history, contact management, scheduled and recurring faxes, and team member access. The desktop layout shows the fax preview alongside your document details for easy review.
Replacing Your Office Fax Machine
If your office still has a fax machine, switching to Best Fax saves money and eliminates headaches. No more buying toner, replacing paper, clearing jams, or paying for a dedicated phone line ($25-40/month). No more walking to the machine to check for incoming faxes. Everything happens in your browser. Your dedicated fax number can be printed on all the same materials your old fax number appeared on — business cards, letterheads, websites, and forms.
Supported File Formats
Best Fax accepts a wide range of document formats: PDF, Microsoft Word (DOC, DOCX), Excel (XLS, XLSX), PowerPoint (PPT, PPTX), images (JPG, PNG, GIF, TIFF), RTF, TXT, CSV, and ODT. Non-PDF files are automatically converted to fax-ready format. You can upload up to 10 files per fax with a total size limit of 50MB and a maximum of 100 pages. Password-protected PDFs are detected and rejected early so you know before paying.
No Admin Rights Needed
Since Best Fax runs entirely in the browser, it works on corporate and managed computers without IT approval or software installation. No admin access required, no printer drivers to configure, no Windows Fax and Scan to set up. This makes it ideal for office environments with strict software policies. Works equally well on Windows, macOS, Linux, and ChromeOS — anywhere you have a modern browser.
