Understanding Resize Modes

Fit Mode (Recommended)

Maintains the original aspect ratio. The image is scaled to fit within the specified dimensions without distortion. This prevents stretching or squashing of your images.

Best for: Profile pictures, product photos, general use

Fill Mode

Scales the image to completely fill the target dimensions. May crop parts of the image if the aspect ratios don't match, but ensures no empty space.

Best for: Thumbnails, cover images, backgrounds

Stretch Mode

Forces the image to exact dimensions regardless of aspect ratio. This can cause distortion but ensures precise sizing when exact dimensions are critical.

Best for: Banners, specific layout requirements

Percentage Mode

Scales the image by a percentage of its original size. Maintains aspect ratio while allowing proportional resizing without specifying exact dimensions.

Best for: Batch processing, uniform scaling
