About this tool
Change an image's width and height in pixels. Keep the aspect ratio to scale proportionally, or switch it off for an exact size. Save as JPG, PNG or WebP. Scaling down stays crisp; scaling up cannot add detail that is not in the original.
Worked example
Resizing a 4000 × 3000 photo to 1200 pixels wide with the aspect ratio kept gives 1200 × 900. Changing only one side without keeping the ratio would stretch the picture.
Common problems and fixes
- The image looks stretched.
- Turn on keep aspect ratio, or crop first so the shape matches the target.
- The image looks soft after enlarging.
- Making an image bigger cannot add detail. Use the upscale tool for a sharper result, or start from a larger original.
- The file got bigger.
- Saving as PNG or at maximum quality can increase size. Choose JPG or WebP for photos.
