In today’s digital world, faxing remains a necessity in many industries. If you work in finance, you know what we mean!
Financial institutions, healthcare professionals, insurance companies, legal offices, and manufacturing still depend heavily on fax features.
The reasoning is that, despite the rise of paperless offices, many organizations still require faxed documents for verification and compliance.
According to Arizton, the global fax services market was valued at $3.46 billion in 2023 and is projected to reach $6.50 billion by 2029, reflecting its continued relevance.
However, with fewer traditional fax machines in modern workplaces, businesses are seeking more efficient alternatives. This raises an important question: ‘How to send a fax online?’ Fortunately, technology has a solution.
With VoIP services, email, or an online fax service, you can convert digital documents into fax format and send them securely.
Options include using an Analog Telephone Adapter (ATA) connected to a VoIP system or a dedicated internet-based fax service, allowing businesses to fax without needing a traditional machine.

How Does Online Faxing Work?
Online faxing uses the same principle as that of traditional faxing, but with a web interface. It converts digital documents into fax-compatible formats, sending them over via internet connection rather than through phone lines.

Unlike traditional faxing, it eliminates the need for a physical fax machine or printing. Users can simply attach PDFs, text documents, or images (for, example, “png” and “jpg” files) to an email and transmit them as faxes instantly.
