HelloFax supports a wide range of files including doc, docx, pdf, ppsx, ppt, pptx, jpg, jpeg, png, xls, xlsx, txt, html and gif files.
If you’d like to use a file type that we don’t support, you can save the file as a pdf and then upload it to hellofax.com. You can also email us at firstname.lastname@example.org - if there’s enough of a demand, we’ll figure out how to support that type of file!
Note: We support a file size of up to 40 MB for each uploaded document in a fax transmission. There is also a maximum total page limit of 250 pages for the HelloFax End-user product.
HelloFax API supports a file size of 40 MB and a page limit of 250 pages.
