Resize an image to the pixel dimensions you need.

Set Choose an image, Width (px), Height (px), Preserve aspect ratio, Output format.
Use Resize to process the input.
Compare the result with your source data and return to the input to make corrections.

1600 × 1200 px → width 800, keep aspect ratio → 800 × 600 px.

Source: up to 40 megapixels. Output: at least 1 px, up to 30 megapixels. PNG ignores quality. JPEG fills transparent areas with white.

Web workflows care mainly about pixel dimensions; print quality depends on pixels and DPI together. Upscaling cannot create real source detail.

For social media, downscale 4000px images to 1600px with aspect ratio locked, inspect a few outputs, then save the batch ZIP.
