Compress a PDF to 4 MB
4 MB is a cap with a famous name behind it: IRCC allows up to 4 MB per document in most online immigration applications, and many other portals use the same ceiling. Scans blow past it easily - a few colour pages from a home scanner can pass 20 MB. This page opens our Compress PDF tool with 4 MB ready as the target, so the shrink stays gentle: lossless first, then the smallest clarity step that brings you under the cap.
How to do it
- Add your PDF file.
- Confirm the target shows 4 MB.
- Click Compress PDF and download, then check the final size before uploading.
Common questions
Is 4 MB really the IRCC limit?
For most documents in IRCC online applications, yes - 4 MB per file is the commonly stated cap. Always confirm the limit shown beside your own upload button, because programs differ.
Can I compress several documents at once?
Run each document separately - portals cap each file individually, so each one needs its own target check.
Are my files uploaded?
No. The tool runs in your browser, which matters for passports and financial records.
