Your immigration documents contain sensitive information — Social Security numbers, financial records, medical data. They stay on your device. No upload.

United States Citizenship and Immigration Services (USCIS) increasingly requires online filing for immigration applications. Each form has specific document upload requirements and file-size limits.

USCIS file-size limits:

- Most online filings: 6 MB per document - Some forms accept up to 25 MB total per submission - Individual document limits vary — check your specific form instructions

Documents commonly uploaded to USCIS:

- Passport biographical pages - Birth certificates and translations - Marriage certificates - Employment authorization documents - Tax returns and W-2 forms - Proof of relationship evidence (I-130) - Medical examination results (I-693)

Why you want this to be client-side.

USCIS filings contain Social Security numbers, alien registration numbers, tax returns, W-2s with employer details, and in I-693 cases, medical information. These are some of the most sensitive documents a person owns. Uploading them to a random compression service puts all of that on a third-party server you don't control. This tool runs compression in your browser — none of it travels over the network.
