What this tool does
Redraws an image at the width and height you specify, with your choice of output format and quality.
How to use it
- Choose the image file.
- Enter the target width and height in pixels.
- Pick the output format and quality.
- Run it and check the resulting dimensions.
Worked example
A 1600×1200 image with a target of 1200×800 returns a 1200×800 image. If that differs from the source ratio, the picture stretches or squashes.
Frequently asked questions
- How do I keep the aspect ratio?
- Work it out yourself: 1600×1200 is 4:3, so a width of 1200 pairs with a height of 900. The tool does not lock the ratio for you.
- Does enlarging a small image sharpen it?
- No. It cannot invent detail, so the result looks soft. If you need a larger image, obtain a higher-resolution original.
