Best Online Fax Services

Small companies can use eFax, a popular and highly reliable online fax service, to send and receive faxes via email or a mobile app in PDF, EFX or TIFF format.

One of eFax’s biggest selling points is the fact that it offers optical character recognition (OCR), which enables users to search through past faxes more easily. Users can also generate reports in CSV and Excel format, based on a particular fax number, employee, client or vendor.

With a strong degree of security, eFax offers 256-bit and TLS 1.2 encryption to protect inbound faxes from unauthorized third parties, whether they’re in transit or stored in the cloud.

Who should use it:

This eFax system is a good solution for smaller companies and sole proprietors that want to move away from paper-based faxing to send and receive faxes from any device. The inclusion of a dedicated account manager will help support new users to get up and running with minimal challenges.
