South Korea K-ETA Photo Specs: Passing the Size Limit

The Ultra-Strict K-ETA Portal

The Korean Electronic Travel Authorization (K-ETA) is required for visa-exempt visitors. The most common point of friction is the photo upload step, which enforces one of the most restrictive file size limits globally: under 100 KB.

Resolution vs. Compression

To hit the 100 KB limit, many applicants shrink their photo dimensions to tiny sizes. However, the system still requires a clear, biometric-quality 700x700 pixel image. The secret is utilizing advanced JPEG compression algorithms to strip out metadata and color depth, rather than physical pixels.

Facial Framing Rules

The K-ETA requires a plain white background, no glasses, no hats, and a neutral expression. The face must be fully visible and centered. Our tool specifically profiles exports to hit the <100 KB threshold while maintaining absolute sharpness.
