FAQ

Is it always under 100 KB?

Yes. Every file is 100 KB or smaller, or it's marked as failed.

My ID photo looks soft.

Crop closer to the face so the pixels go where they matter.

The form still rejects a 100 KB file.

Zelio counts 1 KB as 1,000 bytes, so results also fit systems that use 1,024. Check whether the form wants a specific format or dimensions.

Already under 100 KB?

A JPG that fits is returned untouched.
