Frequently Asked Questions

How is the image resized?

The tool uses your browser’s built‑in Canvas API. It scales your image proportionally, then crops the edges to perfectly fill the iPhone screen dimensions without distortion.

Why does the tool save as PNG?

PNG preserves lossless quality, so your wallpaper looks crisp, and it supports transparency if your original image has it.

Can I resize HEIC photos from my iPhone?

Yes. Modern browsers natively support HEIC images. The tool handles them just like JPEGs and PNGs.
