Meeting Strict Portal Upload Limits (Under 1 MB / 2 MB)
Compress scanned passport pages, bank statements, and notarized affidavits to fit strict 500 KB or 2 MB government e-filing portals.
Compress PDF
Shrink oversized PDF documents so they easily meet strict government portal upload caps, university submission limits, or email attachment restrictions. Choose from four calibrated compression levels—ranging from lossless structural stream cleanup to high-ratio page raster compression—and inspect the exact byte savings before downloading.

Technical Specifications & Best Practices
- ✓Level 1 (Light Clean-Up) optimizes PDF object streams losslessly and keeps all text 100% selectable and searchable.
- ✓Stronger compression levels re-render pages as optimized JPEG images to achieve dramatic size reductions on scanned PDFs, which flattens selectable text into pixels.
- ✓PDFs that already consist purely of plain text with no embedded images are already compact and may show minimal reduction under light cleanup.
- ✓All rendering and compression execute locally on your device CPU without uploading sensitive documents to external servers.
