What happens if my original image is already square?

If you use auto-sizing (Target Size is 0), no padding will be added, and the image will remain as is. If you specify a 'Target Square Size' different from the original, your square image will be scaled to fit within this new target square (maintaining its aspect ratio), and padding will be added if the target size is larger, or it will simply be resized if smaller.

How does the 'Target Square Size' work if my image is larger or smaller than the target?

Your original image will be scaled down or up (while maintaining its aspect ratio) to fit entirely *within* the specified target square size. Padding is then added to fill any remaining space to make the canvas a perfect square of that target dimension, according to your alignment settings.

Why is 'Transparent Background' only available for PNG output?

The PNG image format is widely supported and designed to handle true alpha channel transparency. JPEG format does not support transparency; if you choose JPEG output, the padded areas will be filled with your selected 'Padding Color', even if 'Transparent Background' was previously checked.

Will this tool crop my image to make it square?

No, this Square Padder tool specifically avoids cropping your image. It preserves your entire original image content (potentially scaled if a target size is set) and adds padding around it to achieve the square aspect ratio. If you need to crop, please use our 'Image Cropper' tool.

Can I add a border to the square image with this tool?

This tool focuses on padding to make an image square. To add a distinct visual border around the final square image or your original content within the padding, you can use our 'Image Border Generator' tool after using the Square Padder.
