How image resizer works
Resamples pixels to a target width and height. Lock the aspect ratio to preserve proportions.
Try an example
1920 × 1080 resized to 960 × 540 retains a 16:9 aspect ratio.
Good to know
Upscaling cannot recover missing detail. JPG, PNG and WebP only; 25 MB and 24 megapixels maximum. Output is a single still frame; animation, source colour profiles and metadata are not preserved.
