App Store Resizer was built to solve a common headache for mobile app developers: generating the endless specific image sizes required by the Apple App Store and Google Play Store.
To provide a fast, free, and secure tool that streamlines the app submission process. We believe developers should spend their time building great apps, not resizing screenshots in Photoshop.
Many online resizing tools require you to upload your assets to a server. This is slow and raises privacy concerns. **App Store Resizer runs 100% in your browser.** This ensures your creative assets never leave your device and processing is instant.
This tool is maintained by Miguel Angel Sanchez Peralta, a passionate developer dedicated to creating useful tools for the community.
