How to Reduce PDF Size for IRS, USCIS, and Government Portals
Government websites have strict file size limits. Here's how to compress your PDFs to meet them — without losing readability.
Why This Matters
When you're submitting tax documents to the IRS, immigration forms to USCIS, or applications to any federal agency, a “file too large” error can delay your submission by days or weeks. Don't let a technical issue become a legal headache.
Government Portal File Limits
Here are the official file size limits for major US government portals:
e-File attachments
myUSCIS uploads
Passport & visa applications
Online applications
Document uploads
Why Scanned Documents Are Usually Too Large
The most common problem: scanned documents. When you scan a paper form:
- Each page becomes a high-resolution image (often 200-300 DPI)
- A 10-page document can easily reach 20-30 MB
- Color scans are 3x larger than grayscale
Government portals expect you to compress these before uploading.
How to Compress (Step-by-Step)
Open Our PDF Compressor
Your files stay on your computer — never uploaded to external servers.
Upload Your PDF
Drag and drop your scanned document.
Choose Compression Level
For text-heavy government forms, “Screen” quality usually works fine. For forms with photos, use “Ebook” or “Printer”.
Verify and Download
Check the new file size meets the portal's limit, then download.
Tips for Government Submissions
✅ Keep text readable
Compress enough to meet the limit, but make sure all text (especially signatures and dates) remains legible.
✅ Test before final submission
Open your compressed PDF and zoom in on important details. If anything is blurry, use a lighter compression setting.
✅ Scan in grayscale when possible
For text documents, grayscale scans are 3x smaller than color and usually sufficient.
✅ Split large documents
If compression isn't enough, use our PDF Split tool to divide into smaller parts.
