What is 'percentage scaling'?

Selecting 'by percentage' mode allows you to scale based on the original image size, e.g., 50% means both width and height are reduced to half the original.

Will enlarged images become blurry?

Yes. Enlarging images involves interpolation which reduces clarity. It's recommended to only reduce image size, or use AI super-resolution features for enlargement.

Will batch resizing unify dimensions?

Yes. All images will apply the same dimension settings during batch processing. If using 'Lock Aspect Ratio', images with different original ratios may have slightly different final dimensions.
