App Store Screenshot Resizer
Preparing App Store Connect screenshots means juggling dozens of exact resolutions across six Apple platforms. This free resizer does all of them at once — detect, validate, resize and export a clean ZIP, entirely in your browser.
Open the resizerDrop a batch of screenshots and the tool figures out which Apple devices each one fits, flags anything that's the wrong size or aspect ratio, and resizes everything in parallel using Web Workers so even thousands of images stay fast.
The export mirrors App Store Connect's structure with per-device folders, and there are no accounts, uploads, watermarks or limits. Your screenshots never leave your computer.
