K-ETA photo size and 100 KB upload limit

K-ETA photo preparation is mostly a digital file problem: the face must remain clear while the JPG stays below a strict upload limit.

Quick summary

The practical target: square JPG under 100 KB

Many phone photos are too large for K-ETA because they start as multi-megabyte HEIC or JPEG images. Cropping alone does not solve the file-size problem; the pixel dimensions and JPEG quality both matter.

A 600 x 600 px square image is a practical export target because it leaves room below the published 700 x 700 pixel ceiling while still showing the face clearly after compression.

Why not maximize the image to 700 x 700 px?

A larger square can look sharper before upload, but it is harder to compress under 100 KB without visible artifacts. If the face becomes blocky or blurry, the file may technically upload but still be weak for identity review.

The safer sequence is crop first, resize second, compress third, then inspect the final JPG at normal size.

About official sources

These guides summarize public K-ETA guidance, Korea immigration notices, Korea visa e-Form document guidance, and Korea Visa Portal references. They focus on photo preparation only, not eligibility advice or application submission.

Common photo problems

Most failures are ordinary image problems, not complicated visa rules.

Oversized file

A phone photo can be several MB. Resize first, then compress, so the face remains sharp under the limit.

Wrong photo type

Do not upload a print sheet, a passport scan, or a photo of a printed photo when the portal expects a portrait file.

Weak identity visibility

Shadows, glare, heavy filters, hair over the eyes, or a tilted face can make identity confirmation harder.

Where the app helps

K-ETA crop

Exports a 600 x 600 px JPG for K-ETA-style upload limits.

On-device privacy

Photo processing happens on the iPhone; the app does not upload your image to a server.

Separate Korea visa route

Use the 35 x 45 mm Korea visa mode when your application needs a visa photograph rather than a K-ETA portrait upload.

The app prepares the photo file only. Submit your application through the official route and confirm the latest requirement before using the file.

FAQ

Can I upload a 600 x 600 px K-ETA photo?

A 600 x 600 px JPG is designed to stay below the published less-than-700px limit. Always confirm the latest K-ETA upload screen before submission because portal rules can change.

Is PNG acceptable for K-ETA?

Use JPG/JPEG for the portrait upload unless the current official upload screen explicitly allows another format.

Does under 100 KB mean lower quality is always better?

No. Over-compression can make the face unclear. Resize to a reasonable square first, then compress just enough to stay below the limit.
