Where this number comes from
“IRCC Portal 5 MB”
— Is there a file size limit for documents I upload to my account? (IRCC Help Centre), 2026-09-28. Checked October 2026.
PDF Desk aims at 4.8 MB, a little under the limit, because some portals count 1 KB as 1,000 bytes.
If the file will not get small enough
Scan in black and white at 150 DPI instead of colour. Remove blank and duplicate pages with Delete pages. If the portal allows several files, cut the PDF with Split PDF and upload the parts.

Questions
What is the maximum PDF size for IRCC Portal?
Uploaded documents (per file): 5 MB. Source: ircc.canada.ca, checked October 2026.
IRCC Portal still rejects my PDF. Why?
Check that it is not password-protected, that the file name has no special characters, and that it is a few percent under the limit — some portals count 1 KB as 1,000 bytes.
Are my PDFs uploaded?
No. PDF Desk opens and writes the file with JavaScript inside your browser tab. Nothing is sent to a server, so it is safe for contracts, IDs and bank statements.
