Purpose
What this tool does
This App Store screenshot resizer formats iOS screenshots to the mandatory 6.5-inch Super Retina display resolution (1284 × 2778 pixels) required by App Store Connect. It preserves exact pixel boundaries with zero distortion so your store listing passes Apple review on first submission. It is preconfigured for 1284 × 2778 pixels. Processing happens entirely on your device — your image is decoded, resized, compressed, and prepared for download without being uploaded to any server.
Output
Supported formats and output
Upload JPG, PNG, or WebP. Choose JPG for broad form compatibility and smaller files, WebP where it is accepted, or PNG when transparency and lossless output matter more than an exact KB target.
The result card reports the actual pixel dimensions, format, and file size rather than assuming the target was reached. You can verify the output before downloading.

Before uploading
Common limitations
App Store Connect strictly validates screenshot resolutions down to the single pixel. Uploading a screenshot even 1 pixel off 1284×2778 will cause an immediate rejection during binary processing.
Very large photos can exceed a phone's available memory. If processing fails, try a smaller source image. PNG cannot be compressed by changing quality like JPG or WebP.
Privacy
Private browser processing
Your selected image is decoded, resized, compressed, and downloaded locally in your browser. Normal tool operation does not upload the image or its original filename to our server. The processed result stays on your device until you choose to save or share it.
