YouTube Shorts Cover Resizer Sizing & Upload Guidelines

✓
1. Safe Zone Alignment & Viewport Masking: Keep primary subjects, brand logos, and text centered within the inner 80% safe zone. Mobile applications frequently apply rounded corner viewports or circular avatar masks that crop the outer perimeter of your photo.
✓
2. Color Profile Integrity across Mobile Vendors: Always export your image using the standard sRGB color matrix. Wider color spaces (such as Display P3 or Adobe RGB) often suffer desaturation, tint shifts, or contrast loss when compressed by social media CDNs.
✓
3. Client-Side Pre-Scaling vs. Server Downsampling: Pre-scaling photos to the exact 1080×1920 pixel target before uploading prevents double-compression artifacts, preserves razor-sharp edges, and eliminates server-side processing delays.
