I have been using this service for about 3 years. Your choices are 2 gb free transfers, or up to 20 gb with a pay for plan.
I have found it to be fast, simple, allowing for multiple files to multiple email address at the same time. I have used it for images, documents, software presets that were free on the internet, and an even more extended list.
It is worth keeping the link handy on your desktop computer or mobile device.
WeTransfer is a free service to send big or small files from A to B
