Export checklist
Before you upload
Export the canvas at 512 × 800 px before uploading.
sRGB is the safest color profile for consistent web and app display.
Use JPG for photos and PNG for crisp logo, type, or flat artwork when the platform accepts it.
Keep compressed for mobile readers
Review desktop and mobile previews so cropping, padding, and compression do not hide important content.
Common mistakes
Avoid these image problems
Responsive previews, masks, and thumbnails can crop or soften edge content.
Do not upscale a small file to 512 × 800 px; start with sharp source artwork.
A file outside 16:25 may be cropped, padded, or rejected depending on the upload surface.
Small type often becomes unreadable after mobile scaling and platform compression.
