How to use
1. Image source: Choose a dummy image or upload your own. After uploading, the preview switches to your image.
2. Presets: Enter common social media / ad sizes with one click.
3. Size settings: Enter the width and height of the banner you want to check. Set either to “0” to auto-calculate from the image’s aspect ratio.
4. Display mode: Switch between “cover (fills the frame)”, “contain (shows the whole image)”, and more to check the cropping.
5. Download: Once you upload an image and set a size, the “Download” button becomes active. Save a PNG at the specified size with the chosen display mode applied.
