How to use Image Resizer
Choose an image, enter a width and height, then resize. Keep aspect ratio enabled to avoid distortion.
How it works
Resizing changes pixel dimensions rather than simply changing a file-size label. Downscaling reduces detail and usually saves space; enlarging cannot recover details absent from the original. Locking the aspect ratio keeps the image proportions intact.
Example
1600 × 900 → 800 × 450 with the same aspect ratio.
