Does anyone have any tips for submitting large file-sizes on the eVisa application form? All of my supporting documents are PDFs so I can merge them into a single file but it greatly exceeds the 3MB file limit.

The culprit pages are image-heavy PDF versions of webpages showing my biographies and a few writing samples. I've also included live links to all of these pages on my cover letter/contents page - if there's no way around the file limit, would these links suffice on their own?

Thanks! (And thank you to everyone who's posted so far, this page has been a fantastic resource)
