Where 4 MB usually appears
- IRCC accounts or upload paths that explicitly allow 4 MB.
- Supporting documents with scans, stamps, or fine text that suffer too much at 2 MB.
- Portal workflows where you already confirmed the higher allowance.
Exact size target
Prepare a PDF for a 4 MB upload limit
Use 4 MB when the real portal allows it and the document benefits from extra room for readability. In many workflows, 4 MB is a practical destination, but it is not automatically the safest choice if the actual path might still force 2 MB.
What 4 MB changes
- You have more room for readability than with a 2 MB target.
- You still need to review the result instead of assuming acceptance.
- You still should not switch on extra processing unless the destination asks for it.
Choose 4 MB only when the destination really allows it
This matters most in IRCC-related workflows. Some accounts allow 4 MB, while other paths still force 2 MB. If you are not sure, use the stricter path first and keep 4 MB for the cases where the portal clearly supports it.
IRCC
Use the IRCC guidance, not a generic guess
See IRCC and IRCC file size limits for the 2 MB, 3 MB, and 4 MB framing.
