Why the DS-160 Portal Rejects Oversized Photos
When completing the Nonimmigrant Visa Electronic Application (Form DS-160) or submitting entries to the CEAC portal, users frequently hit a strict error: "The image file size is larger than the maximum allowed size of 240 KB."
Standard image compressors often over-compress the file below 30 KB (triggering the secondary "Image is too compressed / poor quality" warning) or scale down the image dimensions below 600×600 pixels.
DocSnap uses an iterative binary search quantizer inside your browser's canvas. It keeps your image pinned at exactly 600×600 pixels while fine-tuning JPEG chroma subsampling until the file lands reliably between 180 KB and 230 KB.
Frequently Asked Questions
What is the maximum file size allowed on the CEAC DS-160 portal?
The US Department of State Consular Electronic Application Center (CEAC) strictly limits photo uploads to a maximum of 240 KB. Photos exceeding 240,000 bytes produce an automatic upload error.
Does this compressor alter the 600x600 pixel resolution of the photo?
No. The compressor maintains the required 600x600 pixel square geometry and adjusts only the JPEG chroma quantization matrices, ensuring the image remains sharp and valid.
