About these dimensions
Choose the width and height you need. Keeping aspect ratio enabled avoids stretching when only one dimension changes.
Upscaling and aspect ratio
Upscaling a small source does not recreate missing detail. If the source aspect ratio differs from the requested output, a fixed resize can stretch the picture; use a crop tool first when you need exact dimensions without distortion.
