About Image Size Reducer (Resize)

Searches for image size reducer sometimes mean compression, but many users want smaller dimensions — fewer pixels — for faster layouts. This page focuses on resizing: set smaller width/height and export a lighter dimensional footprint.

Use the same controls as Resize Image: pixels, percentages, aspect lock, and download. Pair with Compress Image afterward if you also need smaller KB.
