Last minute fixes to your own paper, like an author affiliation, a typo in a heading or a corrected figure caption, can be made directly in the PDF you're about to submit. Add an invisible text layer to scanned pages so you can search and copy them.

- 2.Add the scanned PDF.
- 3.Download the searchable PDF.

What happens to the rest of the page

LaTeX papers
PDFs from LaTeX often embed fonts with only the characters used. Small corrections usually work; longer additions are best made in the source.
Add supplements
Combine the paper with supplementary material using Merge PDF.
