US photo tool: “Overall image quality may be poor (low resolution, lack of clarity, or overly compressed)”

What the message means

The tool shows it under “Your photo has been rejected for the following reason(s):”. In the tool’s code, the check compares the number of pixels with the size of the file: if the file is very small for an image of that size, the photo has been compressed so much that detail is lost.

The State Department’s digital image rules set the limit: “The compression ratio should be less than or equal to 20:1.” For a 600×600 colour photo, that works out to a file of at least about 54 KB, while the DS-160 and DV upload limit is 240 KB.

Why it happens

• The photo was saved at a low JPEG quality to make it small.
• It was compressed again by a chat app, email or a website before you saved it.
• It was enlarged from a small photo, which makes it blurry even if the file is large enough.
• It was taken in poor light, so the camera smoothed away the detail.

How to fix it

1. Start from the original photo from the camera, not a copy that was shared or downloaded.
2. Crop it to a square from the original, so the result is at least 600×600 without enlarging.
3. Save the JPEG at a high quality so the file lands between about 54 KB and 240 KB.
4. If it’s still blurry, retake it in daylight with the phone held still.

Check it before you upload

IDPlain checks the file size, resolution and sharpness of your photo for free. When it makes the 600×600 file, it picks the highest JPEG quality that stays within 240 KB.
