Resizing without losing quality
Making an image smaller keeps it sharp, because several original pixels are averaged into each new one. This tool reduces large images in steps for a cleaner result. Making an image larger cannot add detail that was never there, so enlargements beyond about 150–200% start to look soft.
Pixels, file size and print size
- Pixel dimensions are the width and height of the image, such as 1920 × 1080.
- File size depends on the pixel count, the format and the quality setting. Halving both sides cuts the pixel count to a quarter.
- Print size is pixels divided by print resolution: 1800 × 1200 pixels prints at 6 × 4 inches at 300 dpi.
