Best for scanned documents and image-heavy PDFs (the kind exam portals reject for size).

Get your documents under the USCIS upload limit

Filing online through myUSCIS caps the size of each document you upload, and a scanned passport, birth certificate or supporting letter is often too large. This tool shrinks your PDF enough to fit while keeping the pages clearly readable — exactly what a reviewer needs.

Because immigration documents are sensitive, it matters that nothing is uploaded: the compression runs on your own device. If a file is still too big, scan in greyscale, split long documents, or compress to a specific target such as 1 MB or 500 KB.

⚠️ USCIS file-size and format rules can change and vary by form — always confirm the current requirements on uscis.gov before you upload. ToolsKaro is not affiliated with USCIS or any government agency.

Frequently asked questions

What is the file size limit for USCIS uploads?
When filing online through your myUSCIS account, each uploaded file must be under a set size and in an accepted format (usually PDF or JPG). The exact limit can change, so always confirm the current requirement on uscis.gov before submitting.
How do I compress a document for USCIS?
Upload your scanned PDF above and the tool reduces its size while keeping the text readable, then lets you download it. Scanned and photo-based documents compress the most. Everything runs in your browser.
Will my immigration documents stay private?
Yes. Nothing is uploaded — the compression happens entirely on your own device, which matters when handling sensitive immigration paperwork.
My scan is too large for USCIS — what should I do?
Scan in black-and-white or greyscale where possible and run the file through this compressor. If it is still too large, split it into separate documents or compress to a specific target like 1 MB.
Is it free with no watermark?
Yes — completely free, no watermark, no sign-up and no email.
