MightyFax - Fax software to send and receive faxes right from your PC !


No Fax Machine Required. All you need to use our fax program is a telephone line and the modem you already have in your computer.

Reliable. MightyFax is a solid and reliable program, and has stood the test of time. It has been used by thousands of users on every imaginable combination of hardware and software.

Compatible. MightyFax works on Windows XP Home or Professional. It will also work with most modems without further configuration.  If you are looking for fax software for Windows Vista, please consider our new RKS Fax software (which also works in Windows XP).

Easy to use. The #1 comment we get about MightyFax is how easy it is to use. That's because it was designed to be a fax program first and foremost. It does not try to take over your computer, and it does not try to be more than a fax program. Customers tell us it is the most user-friendly pc fax software they have found. Simply print your document to our fax printer driver to create a fax.


Easy Setup

Setting up is easy, and in most cases you can simply run the installation program and immediately start creating, sending and receiving faxes from your pc.

Ideal for Personal or Small Business.

Mightyfax is suggested for use as personal fax software, or small business fax software

MightyFax News and Releases

Apr 22, 2008 3.62 Changes the Preferences button to Settings (easier to understand)
Additional small changes and tweaks
Mar 12, 2008 3.61 Fixes an error with locating the file SDE61.DLL. If you've downloaded version 3.60, this is an essential download.
Feb 29, 2008 3.60 Added PDF (single or multi-page) and JPEG (single page) to the Export Fax screen. (available to registered users only)

Dec 13, 2007 3.41 Adds the correct file extension when exporting a fax to TIF, BMP etc., if the user forgot to add the file extension when saving

Modified the way Configuration Info is presented - this will help support better diagnose problems

Updated SDE61.DLL for Portuguese Windows problem
Oct 13, 2007 3.40 If a fax was created in low resolution, or a fax was received in low resolution, and a cover page was used, the fax would show as stretched width-wise, because the cover is always created in high resolution. If this situation is detected now, the cover will be reduced to match the resolution of the fax. (this did not effect sending or faxes, just viewing).

When editing a fax with a cover sheet, if just clicking Edit and then Save, without changing the cover sheet text, the cover sheet would not be saved.
May 22, 2007 3.39 New more efficient memory manager

Receive grid was losing its filter setting when receiving a new fax. Fixed.

Jan 3, 2007 3.38 Added a fix for rare "floating point" error when printing to certain HP Color Laserjets over a network.

Added Preference item #22c - "Automatically stop/resume receive mode when sending". Turn this on if you want MightyFax to automatically stop receive mode when you click the send button, and then restart receive mode when you are done sending (but only if currently in receive mode). The default is for this to be enabled.
Nov 2, 2006 3.37 When entering/editing a phone book entry from the printer driver dialog box, accented characters ( å, ä, ö etc) were sometimes being translated wrongly. The file MFNTCTL.EXE is replaced to fix this.

When printing a fax that was less than full page size, it was always stretched, even when the "Stretch/shrink faxes to fit on page" option was unchecked. Fixed.
Oct 2, 2006 3.36 Fixed memory leak when viewing faxes.
Fixed an error with printing fax logs when selecting "Only Archived Faxes"
Aug 23, 2006 3.35 Multiline text was not working properly for the coversheet editor. Now works properly.
Configuration Information now correctly reports the CPU brand and type.
Aug 7, 2006 3.34 Adds a tutorial on creating faxes
June 22, 2006 3.33 Fixed some issues with the new Import Phonebook tool
May 8, 2006 3.32 Fax Viewer now gives clearer representation of fax with graphics

New menu option File > Import Phonebook Entries. This implements importing from comma-delimited ( CSV ) files. ( Most Windows programs, including Outlook, can export their phonebooks in CSV format. )
Jan 18, 2006 3.31 On the "Incoming Faxes" tab, the "View" and "Sort by" filters were not working. This has now been fixed.
Jan 11, 2006 3.30 Added Receive Incoming Fax Now - Call currently in progress (manual receive) option as both a dropdown menu option on the Receive button, and as a main menu option. Use this method when you share the same line for voice and faxing, answering all incoming calls with a telephone, and you have answered the telephone and hear a fax tone. (see Help file for expanded instructions and description)

Enhanced the main screen toolbars and menus with additional icons as a visual aid

Changed Cover Sheet Template Designer most recently used file list so that it will auto-correct its file list if the MightyFax folder has been manually moved


For earlier releases, please see the version history page.

What our customers say...

"This fax software is very easy to use, which is the feature I like best."

"This is the most user-friendly program ever made. Even the most novice user can master this program in a matter of minutes."

"Your program is a nice SMALL alternative to Winfax Pro. It's wonderful to find a program that does what I want it to do - faxing without trying to also organize my recipe files!"

"Finally!! Affordable fax software that works with my scanner! Thank you so much!!!"

"The perfect Fax program! I have used a variety of Fax software and nothing compares in its simplicity and ease of use"

"After five working days trying to find a fax program to use, MightyFax took less than thirty minutes."

"Just a short thank you for remaining a good supplier and supporter of good software - in particular MightyFax. I purchased it about 2 years ago and you are still supporting it at zero cost for existing users. This program has always been stable and effective and only gets better."

"I recently purchased your MightyFax 3.08 after struggling with Window$ XP's fax driver. Thank you for writing excellent software, reasonably priced! I was skeptical about the program working with XP. It has worked very well. In fact, I think it works faster than the bloatware of WinFax Pro or Window$ own fax driver. I am pleased with this software and I wish more software delivered like this. Please keep up the good work and I will try some of your other software."
