Troubleshooting & Fixes

Common Errors & Troubleshooting Guide

Quick solutions to common upload errors, portal rejections, and browser canvas issues

Why this happens:

JPEG format does not support transparency. Unmanaged converters render transparent alpha pixels as black (#000000).

Our converter automatically replaces transparency with clean solid white (#FFFFFF) for seamless portal compliance.
