What people are asking
Tax pros and admins hitting portal megabyte caps; Facebook groups compressing bank statements for immigration portals.
The return is correct; the portal just hates 45MB of scanned K-1s. Compress, then upload.
What Compress PDF actually does
- Recompress page images with presets aimed at email/portal caps.
- Batch ZIP for multiple returns or statements.
What it does not do
- Change IRS business rules (page size, PDF version)—only file weight from image recompression.
Steps
- Open Compress PDF.
- Use a stronger preset if the portal still rejects.
- Proofread critical pages; upload again.
- If size is fine but page count is wrong, fix with Split/Extract—not more compression.
