Export is the final quality gate in an app screenshot workflow. The best format depends on where the image will be uploaded, how much detail it contains, and whether file size or lossless quality matters most.
Choose a format for the destination
PNG is useful for sharp interface graphics and text. JPG can reduce photographic file sizes, while WebP is practical for web previews where supported.
Confirm dimensions before exporting
Select the intended store or campaign format early and inspect every adapted layout. Resizing at the end can introduce unintended crops and small typography.
Select the correct pages
Export only approved slides and verify their order. This prevents drafts or alternate concepts from being included in the upload package.
Review sharpness and color
Open the exported files rather than relying only on the editor preview. Inspect small text, device edges, gradients, shadows, and transparent areas.
Use predictable filenames and folders
Organize assets by platform, device, language, and version. A repeatable naming system makes review and future creative updates much safer.
Next Steps
Apply these principles in the RenderDuck editor, keep the strongest product proof at the center of each composition, and use a consistent template for future updates.
