Why platform-specific resizers beat a generic image resizer
A general resizer lets you type any dimensions. That's useful, but it doesn't tell you where the platform will crop, which corners get covered by UI chrome, or what the maximum file size actually is. These tools pre-load the correct dimensions and show you exactly where text and subjects need to sit to avoid being cropped on different devices and layouts.
YouTube Shorts, for example, covers the bottom 420px with UI buttons on mobile — a detail most resizers never mention. If your call-to-action sits in that zone, viewers on phones will never see it. The safe zone overlay in our Shorts tool shows this danger area on your actual image before you upload.
