Scan for USCIS

The problem

myUSCIS online filing requires PDFs, capped at 12 MB per file. You've got birth certificates, marriage certificates, tax transcripts, pay stubs, photos, and translations to upload as evidence — and you're holding a phone, not a flatbed scanner. Compress too aggressively and the text becomes "super grainy" (real quote from r/USCIS) and may be rejected as illegible. Compress too little and you blow the 12 MB cap.

The fix

PDFThis turns each photo into a clean, legible, USCIS-friendly PDF that lands well under USCIS's 12 MB limit on its own. Page detection finds the document, perspective correction flattens the angle, and the result looks like a real scan rather than a phone snapshot — exactly what an officer reviewing your evidence expects. Multi-page documents become multi-page PDFs; each page stays sharp.

What you get

  • USCIS allows up to 12 MB per file when filing online — PDFThis output is typically 1-3 MB per single page, well under that ceiling.
  • Black-and-white scanner mode produces sharp, professional-looking pages — the kind of output USCIS reviewers see daily from attorneys and accredited preparers.
  • Color mode preserves anything with intentional color: hospital records with stamps, marriage certificates with seals, official translations with colored notary marks.
  • Files are processed in memory and never stored — important when uploading sensitive immigration documents like Social Security cards or birth certificates.
