Resize vs. Compress — What Is the Difference?
Resizing changes the pixel dimensions of the image. A 4000 × 3000 px photo resized to 800 × 600 px has fewer pixels — it is physically smaller. This reduces file size significantly.
Compressing keeps the same dimensions but reduces the quality/detail of the encoded pixels to make the file smaller. Use Image Compress for this.
For maximum size reduction: resize first to the dimensions you actually need, then compress.
