Exact size
Start with the 12 MB path
If you only need the size limit, start with the 12 MB guide.
Prepare supporting PDFs for USCIS-style uploads under 12 MB
USCIS-style uploads often come down to a 12 MB limit per file. Even then, the PDF still needs to be clean and readable. PDF Ready helps you prepare supporting PDFs on your device, but it does not guarantee acceptance and it should not replace untouched validated originals.
In the app
USCIS still starts from the exact-size step
USCIS-style uploads still use the same exact-size step. Choose 12 MB when the real upload allows it.
- Use 12 MB when the destination clearly allows more room.
- Review readability before you export the final clean copy.
- Keep the original file if the source document needs to remain untouched.
What this portal guide is for
- Supporting PDFs for USCIS-style online filing.
- Cases where 12 MB gives you more room than a 2 MB or 4 MB upload limit.
- Sensitive files that you would rather prepare on your own device first.
What to keep in mind
- Always verify the current instructions of the actual form or upload path.
- Keep the original file when the source app or portal requires an untouched validated state.
- Use visible signature or photo placement only when the destination accepts a modified supporting document.
- Keep filenames simple, short, and safe for upload.
Practical USCIS checks
- 12 MB is the baseline, not a promise: being under the size limit does not guarantee a successful upload.
- Accepted formats in practical terms: USCIS upload paths usually talk in terms of PDF and common image formats, but PDF Ready is focused on preparing PDFs. If you start from photos, turn them into a PDF first.
- No encrypted or password-protected PDFs: unlock them first or keep the untouched original if the source requires it.
- Translations still matter: non-English evidence may need a full English translation with the translator statement required by the real USCIS instructions.
- Under the limit can still fail: odd PDF structures, malformed exports, protected files, or upload-session issues can still cause rejection.
Privacy
Keep case files local
Use compress without uploading when the evidence contains personal or case-sensitive data.
Diagnosis
When the portal still rejects the file
Use why uploads get rejected to check for restrictions, odd structures, or format issues.
