Compress PDF documents to meet USCIS and US visa application file size limits free online. Get scanned documents under 2MB per file. No signup needed.

If you're filing through USCIS online or submitting visa documents through the Consular Electronic Application Center (CEAC), you've likely hit a wall: individual scanned files must be no larger than 2MB each, and zipped files aren't accepted at all. A single passport-quality scan can easily exceed that. ## The USCIS and CEAC File Size Problem Most immigration portals require each supporting document — your passport copy, bank statements, employment letters, marriage certificates — as a separate file capped at 2MB. USCIS forms like I-485 or I-765 also expect clear, readable scans, which pushes file sizes up even further if you scan at high resolution. ## Steps to Compress PDF for USCIS Submission 1. Go to [pdfhub24.com/compress-pdf](/compress-pdf) 2. Upload each scanned document separately — don't combine multiple documents into one file unless the instructions say to 3. Select **High Compression** 4. Download and check the file size shows under 2MB 5. Repeat for each required document, keeping them as individual files ## Common Mistakes That Cause Rejections **Combining documents incorrectly:** CEAC treats a bill of lading, invoice, and license saved in one PDF as a single file — but immigration evidence usually needs to stay separated by document type. Check your specific form's instructions before merging anything. **Scanning too high:** 600 DPI color scans of a passport can hit 5-8MB before compression. Scan at 200-300 DPI in color for photos and ID pages — this alone keeps file sizes manageable without needing aggressive compression that blurs text. **Re-scanning printed PDFs:** If you already have a digital PDF (like an employment offer letter), never print and re-scan it. Compress the original digital file instead — it'll be a fraction of the size and far more legible. ## For Large Document Bundles USCIS forms for marriage-based petitions or H-1B applications can require 100-200+ pages of combined evidence. If you must submit a large bundle as one file, split it first using [pdfhub24.com/split-pdf](/split-pdf), compress each part separately, then check whether your specific form portal accepts multi-part submissions.
