Although mainly Mega is a Cloud service but its PDF reader is extremely fast compared to other PDF readers. The only thing is it reduces image quality but it's not much so you wouldn't really care. It's really fast at loading pages on PDF file up to 50-80MB.
All files uploaded to Mega are first encrypted on the users side. To access files a decryption key must be supplied. For ease of use, the decryption key can be appended to the URL you share.
Just drag and drop files in the browser window, then create a link for sharing. You will need an account to create a link. To streamline the process for new users you can start uploading as soon as you access the website and create an account while it's uploading.
