File Types Supported by Email-to-Fax Services
If you work with different types of files on daily basis, you need an online fax service that is capable of converting multiple documents to fax.
File compatibility is an important aspect to take into account when picking a provider, after all that’s a big part of what makes online faxing such a powerful tool! The files you attach in your Gmail fax or that you send via your online fax account are all automatically converted into a fax image, a TIFF file actually, and then forwarded to the receiving fax machine.
Common Compatible Formats
These are the file types that are supported by the vast majority of online fax services out there. Keep in mind that there are also websites that let you fax for free by following a simple form. These websites offer a very limited amount of supported formats. Some only allows you to upload PDFs, while other accept TXT and JPG files.

There are additional factors that you should keep in mind though, like the size of files you are going to share and the amount of pages your documents are going to include. If you work with large files, maybe you would be better with a service that is able to do so, and you convert your documents to a compatible file format manually.
