Resize any image for phone wallpaper (1080×2340) — free, instant, private.
Phone wallpapers at 1080x2340 pixels fit most modern smartphones with their tall, narrow displays. This resolution covers the majority of Android phones and iPhones with notch or Dynamic Island displays. Using a wallpaper sized to your phone's resolution prevents the image from being cropped or scaled by your device, ensuring sharp, full-screen display on both the lock screen and home screen.
Story Format is a free, browser-based resizer built for speed and privacy. Unlike other tools, your files are never uploaded to any server — all processing happens locally in your browser. There's no sign-up, no watermark, and no limit on how many files you can convert. It supports both images (JPG, PNG, WebP) and videos (MP4, MOV, WEBM) with audio preserved.
