If you have mockups or designs in one size but need App Store or Google Play screenshot dimensions, you need to resize without losing quality. Use a tool that accepts multiple images and outputs every required size in one ZIP.
Workflow
Export your screens (or composite them in a design tool), then upload to a screenshot resizer. Select iOS, Android, or both. The tool generates all official sizes (e.g. 1290×2796 for iPhone 6.7", 1080×1920 for Android phone). Download the ZIP and upload to App Store Connect or Google Play Console.
Batch and custom
Resize several screenshots at once so every asset is consistent. For custom dimensions (e.g. social or marketing), use a custom resize tool that lets you set width and height and download multiple resized images in a ZIP.
