About this Preset
Scaling an image by percentage is the easiest way to shrink dimensions while strictly preserving original aspect ratios. Rather than calculating exact pixel values, simply select 50% to reduce both width and height by half (which reduces total image pixel volume by 75%), or choose any percentage from 10% to 90%. Our tool provides real-time dimension feedback and file weight preview.
