Upload PDF questions
Why do upload portals reject PDFs?
Most portals limit file size to keep uploads fast and storage controlled. Compression can help when the PDF has compressible images or metadata.
Can I sign the PDF after compressing it?
Yes. If you still need a visible signature, use the PDF signing tool after compression or before the final upload.
Should I compress before or after merging PDFs?
For multi-document submissions, merge first when page order matters, then compress the final PDF.
