Comece com a restrição de entrega
Do not upload a working draft if the system expects one final file.
Build the exact submission copy with the right pages, the right filename, and the right size before the upload step starts.

The most common problems are oversized attachments, wrong page order, unreadable scans, and unnecessary password protection.
If the portal has a size cap, compress or split the file before the submission attempt instead of waiting for the rejection screen.
Perguntas frequentes
Should I password-protect a PDF before uploading to a portal?
Only if the destination explicitly expects that. Many portals reject protected PDFs because they cannot process them afterward.
What is the safest submission workflow?
Prepare one clean output, verify its pages and readability, then upload that exact version once.
