Merge PDF vs Compress PDF — Which Do You Need?
Students often need both: merge annexures first, then compress the final upload.
Merge PDF
- Combine multiple files into one
- Total size = sum of parts
- Best for annexure order
Compress PDF
- Reduce KB of a single PDF
- May affect scan quality
- Best for strict portal caps
Merge when you have many files; compress when one PDF exceeds the portal KB limit.
